54  * DOC: Station handling
55  *
56  * Stations are added per interface, but a special case exists with VLAN
57  * interfaces. When a station is bound to an AP interface, it may be moved
58  * into a VLAN identified by a VLAN interface index (%NL80211_ATTR_STA_VLAN).
59  * The station is still assumed to belong to the AP interface it was added
60  * to.
61  *
62  * Station handling varies per interface type and depending on the driver's
63  * capabilities.
64  *
65  * For drivers supporting TDLS with external setup (WIPHY_FLAG_SUPPORTS_TDLS
66  * and WIPHY_FLAG_TDLS_EXTERNAL_SETUP), the station lifetime is as follows:
67  *  - a setup station entry is added, not yet authorized, without any rate
68  *    or capability information, this just exists to avoid race conditions
69  *  - when the TDLS setup is done, a single NL80211_CMD_SET_STATION is valid
70  *    to add rate and capability information to the station and at the same
71  *    time mark it authorized.
72  *  - %NL80211_TDLS_ENABLE_LINK is then used
73  *  - after this, the only valid operation is to remove it by tearing down
74  *    the TDLS link (%NL80211_TDLS_DISABLE_LINK)
75  *
76  * TODO: need more info for other interface types

79 /**
80  * DOC: Frame transmission/registration support
81  *
82  * Frame transmission and registration support exists to allow userspace
83  * management entities such as wpa_supplicant react to management frames
84  * that are not being handled by the kernel. This includes, for example,
85  * certain classes of action frames that cannot be handled in the kernel
86  * for various reasons.
87  *
88  * Frame registration is done on a per-interface basis and registrations
89  * cannot be removed other than by closing the socket. It is possible to
90  * specify a registration filter to register, for example, only for a
91  * certain type of action frame. In particular with action frames, those
92  * that userspace registers for will not be returned as unhandled by the
93  * driver, so that the registered application has to take responsibility
94  * for doing that.
95  *
96  * The type of frame that can be registered for is also dependent on the
97  * driver and interface type. The frame types are advertised in wiphy
98  * attributes so applications know what to expect.
99  *
100  * NOTE: When an interface changes type while registrations are active,
101  *       these registrations are ignored until the interface type is
102  *       changed again. This means that changing the interface type can
103  *       lead to a situation that couldn't otherwise be produced, but
104  *       any such registrations will be dormant in the sense that they
105  *       will not be serviced, i.e. they will not receive any frames.
106  *
107  * Frame transmission allows userspace to send for example the required
108  * responses to action frames. It is subject to some sanity checking,
109  * but many frames can be transmitted. When a frame was transmitted, its
110  * status is indicated to the sending socket.
111  *
112  * For more technical details, see the corresponding command descriptions
113  * below.

116 /**
117  * DOC: Virtual interface / concurrency capabilities
118  *
119  * Some devices are able to operate with virtual MACs, they can have
120  * more than one virtual interface. The capability handling for this
121  * is a bit complex though, as there may be a number of restrictions
122  * on the types of concurrency that are supported.
123  *
124  * To start with, each device supports the interface types listed in
125  * the %NL80211_ATTR_SUPPORTED_IFTYPES attribute, but by listing the
126  * types there no concurrency is implied.
127  *
128  * Once concurrency is desired, more attributes must be observed:
129  * To start with, since some interface types are purely managed in
130  * software, like the AP-VLAN type in mac80211 for example, there's
131  * an additional list of these, they can be added at any time and
132  * are only restricted by some semantic restrictions (e.g. AP-VLAN
133  * cannot be added without a corresponding AP interface). This list
134  * is exported in the %NL80211_ATTR_SOFTWARE_IFTYPES attribute.
135  *
136  * Further, the list of supported combinations is exported. This is
137  * in the %NL80211_ATTR_INTERFACE_COMBINATIONS attribute. Basically,
138  * it exports a list of "groups", and at any point in time the
139  * interfaces that are currently active must fall into any one of
140  * the advertised groups. Within each group, there are restrictions
141  * on the number of interfaces of different types that are supported
142  * and also the number of different channels, along with potentially
143  * some other restrictions. See &enum nl80211_if_combination_attrs.
144  *
145  * All together, these attributes define the concurrency of virtual
146  * interfaces that a given device supports.

150  * DOC: packet coalesce support
151  *
152  * In most cases, host that receives IPv4 and IPv6 multicast/broadcast
153  * packets does not do anything with these packets. Therefore the
154  * reception of these unwanted packets causes unnecessary processing
155  * and power consumption.
156  *
157  * Packet coalesce feature helps to reduce number of received interrupts
158  * to host by buffering these packets in firmware/hardware for some
159  * predefined time. Received interrupt will be generated when one of the
160  * following events occur.
161  * a) Expiration of hardware timer whose expiration time is set to maximum
162  * coalescing delay of matching coalesce rule.
163  * b) Coalescing buffer in hardware reaches it's limit.
164  * c) Packet doesn't match any of the configured coalesce rules.
165  *
166  * User needs to configure following parameters for creating a coalesce
167  * rule.
168  * a) Maximum coalescing delay
169  * b) List of packet patterns which needs to be matched
170  * c) Condition for coalescence. pattern 'match' or 'no match'
171  * Multiple such rules can be created.

277  *	has a private regulatory domain, it will be returned. Otherwise, the
278  *	global regdomain will be returned.
279  *	A device will have a private regulatory domain if it uses the
280  *	regulatory_hint() API. Even when a private regdomain is used the channel
281  *	information will still be mended according to further hints from

283  *	is now available which will returns the global regdomain as well as
284  *	all private regdomains of present wiphys (for those that have it).
285  *	If a wiphy is self-managed (%NL80211_ATTR_WIPHY_SELF_MANAGED_REG), then
286  *	its private regdomain is the only valid one for it. The regulatory
287  *	core is not used to help with compliance in this case.
288  * @NL80211_CMD_SET_REG: Set current regulatory domain. CRDA sends this command
289  *	after being queried by the kernel. CRDA replies by sending a regulatory
290  *	domain structure which consists of %NL80211_ATTR_REG_ALPHA set to our
291  *	current alpha2 if it found a match. It also provides
292  * 	NL80211_ATTR_REG_RULE_FLAGS, and a set of regulatory rules. Each
293  * 	regulatory rule is a nested set of attributes  given by
294  * 	%NL80211_ATTR_REG_RULE_FREQ_[START|END] and
295  * 	%NL80211_ATTR_FREQ_RANGE_MAX_BW with an attached power rule given by
296  * 	%NL80211_ATTR_REG_RULE_POWER_MAX_ANT_GAIN and
297  * 	%NL80211_ATTR_REG_RULE_POWER_MAX_EIRP.
298  * @NL80211_CMD_REQ_SET_REG: ask the wireless core to set the regulatory domain
299  * 	to the specified ISO/IEC 3166-1 alpha2 country code. The core will
300  * 	store this as a valid request and then query userspace for it.
301  *
302  * @NL80211_CMD_GET_MESH_CONFIG: Get mesh networking properties for the
303  *	interface identified by %NL80211_ATTR_IFINDEX
304  *
305  * @NL80211_CMD_SET_MESH_CONFIG: Set mesh networking properties for the
306  *      interface identified by %NL80211_ATTR_IFINDEX
307  *
308  * @NL80211_CMD_SET_MGMT_EXTRA_IE: Set extra IEs for management frames. The
309  *	interface is identified with %NL80211_ATTR_IFINDEX and the management
310  *	frame subtype with %NL80211_ATTR_MGMT_SUBTYPE. The extra IE data to be
311  *	added to the end of the specified management frame is specified with
312  *	%NL80211_ATTR_IE. If the command succeeds, the requested data will be
313  *	added to all specified management frames generated by
314  *	kernel/firmware/driver.
315  *	Note: This command has been removed and it is only reserved at this
316  *	point to avoid re-using existing command number. The functionality this
317  *	command was planned for has been provided with cleaner design with the
318  *	option to specify additional IEs in NL80211_CMD_TRIGGER_SCAN,
319  *	NL80211_CMD_AUTHENTICATE, NL80211_CMD_ASSOCIATE,
320  *	NL80211_CMD_DEAUTHENTICATE, and NL80211_CMD_DISASSOCIATE.
321  *
322  * @NL80211_CMD_GET_SCAN: get scan results
323  * @NL80211_CMD_TRIGGER_SCAN: trigger a new scan with the given parameters
324  *	%NL80211_ATTR_TX_NO_CCK_RATE is used to decide whether to send the
325  *	probe requests at CCK rate or not. %NL80211_ATTR_MAC can be used to
326  *	specify a BSSID to scan for; if not included, the wildcard BSSID will
327  *	be used.
328  * @NL80211_CMD_NEW_SCAN_RESULTS: scan notification (as a reply to
329  *	NL80211_CMD_GET_SCAN and on the "scan" multicast group)
330  * @NL80211_CMD_SCAN_ABORTED: scan was aborted, for unspecified reasons,
331  *	partial scan results may be available
332  *
333  * @NL80211_CMD_START_SCHED_SCAN: start a scheduled scan at certain
334  *	intervals and certain number of cycles, as specified by
335  *	%NL80211_ATTR_SCHED_SCAN_PLANS. If %NL80211_ATTR_SCHED_SCAN_PLANS is
336  *	not specified and only %NL80211_ATTR_SCHED_SCAN_INTERVAL is specified,
337  *	scheduled scan will run in an infinite loop with the specified interval.
338  *	These attributes are mutually exculsive,
339  *	i.e. NL80211_ATTR_SCHED_SCAN_INTERVAL must not be passed if
340  *	NL80211_ATTR_SCHED_SCAN_PLANS is defined.
341  *	If for some reason scheduled scan is aborted by the driver, all scan
342  *	plans are canceled (including scan plans that did not start yet).
343  *	Like with normal scans, if SSIDs (%NL80211_ATTR_SCAN_SSIDS)
344  *	are passed, they are used in the probe requests.  For
345  *	broadcast, a broadcast SSID must be passed (ie. an empty
346  *	string).  If no SSID is passed, no probe requests are sent and
347  *	a passive scan is performed.  %NL80211_ATTR_SCAN_FREQUENCIES,
348  *	if passed, define which channels should be scanned; if not
349  *	passed, all channels allowed for the current regulatory domain
350  *	are used.  Extra IEs can also be passed from the userspace by
351  *	using the %NL80211_ATTR_IE attribute.  The first cycle of the
352  *	scheduled scan can be delayed by %NL80211_ATTR_SCHED_SCAN_DELAY
353  *	is supplied.
354  * @NL80211_CMD_STOP_SCHED_SCAN: stop a scheduled scan. Returns -ENOENT if
355  *	scheduled scan is not running. The caller may assume that as soon
356  *	as the call returns, it is safe to start a new scheduled scan again.
357  * @NL80211_CMD_SCHED_SCAN_RESULTS: indicates that there are scheduled scan
358  *	results available.
359  * @NL80211_CMD_SCHED_SCAN_STOPPED: indicates that the scheduled scan has
360  *	stopped.  The driver may issue this event at any time during a
361  *	scheduled scan.  One reason for stopping the scan is if the hardware
362  *	does not support starting an association or a normal scan while running
363  *	a scheduled scan.  This event is also sent when the
364  *	%NL80211_CMD_STOP_SCHED_SCAN command is received or when the interface
365  *	is brought down while a scheduled scan was running.
366  *
367  * @NL80211_CMD_GET_SURVEY: get survey resuls, e.g. channel occupation
368  *      or noise level
369  * @NL80211_CMD_NEW_SURVEY_RESULTS: survey data notification (as a reply to
370  *	NL80211_CMD_GET_SURVEY and on the "scan" multicast group)
371  *
372  * @NL80211_CMD_SET_PMKSA: Add a PMKSA cache entry, using %NL80211_ATTR_MAC
373  *	(for the BSSID) and %NL80211_ATTR_PMKID.
374  * @NL80211_CMD_DEL_PMKSA: Delete a PMKSA cache entry, using %NL80211_ATTR_MAC
375  *	(for the BSSID) and %NL80211_ATTR_PMKID.
376  * @NL80211_CMD_FLUSH_PMKSA: Flush all PMKSA cache entries.
377  *
378  * @NL80211_CMD_REG_CHANGE: indicates to userspace the regulatory domain
379  * 	has been changed and provides details of the request information
380  * 	that caused the change such as who initiated the regulatory request
381  * 	(%NL80211_ATTR_REG_INITIATOR), the wiphy_idx
382  * 	(%NL80211_ATTR_REG_ALPHA2) on which the request was made from if
383  * 	the initiator was %NL80211_REGDOM_SET_BY_COUNTRY_IE or
384  * 	%NL80211_REGDOM_SET_BY_DRIVER, the type of regulatory domain
385  * 	set (%NL80211_ATTR_REG_TYPE), if the type of regulatory domain is
386  * 	%NL80211_REG_TYPE_COUNTRY the alpha2 to which we have moved on
387  * 	to (%NL80211_ATTR_REG_ALPHA2).
388  * @NL80211_CMD_REG_BEACON_HINT: indicates to userspace that an AP beacon
389  * 	has been found while world roaming thus enabling active scan or
390  * 	any mode of operation that initiates TX (beacons) on a channel
391  * 	where we would not have been able to do either before. As an example
392  * 	if you are world roaming (regulatory domain set to world or if your
393  * 	driver is using a custom world roaming regulatory domain) and while
394  * 	doing a passive scan on the 5 GHz band you find an AP there (if not
395  * 	on a DFS channel) you will now be able to actively scan for that AP
396  * 	or use AP mode on your card on that same channel. Note that this will
397  * 	never be used for channels 1-11 on the 2 GHz band as they are always
398  * 	enabled world wide. This beacon hint is only sent if your device had
399  * 	either disabled active scanning or beaconing on a channel. We send to
400  * 	userspace the wiphy on which we removed a restriction from
401  * 	(%NL80211_ATTR_WIPHY) and the channel on which this occurred
402  * 	before (%NL80211_ATTR_FREQ_BEFORE) and after (%NL80211_ATTR_FREQ_AFTER)
403  * 	the beacon hint was processed.
404  *
405  * @NL80211_CMD_AUTHENTICATE: authentication request and notification.
406  *	This command is used both as a command (request to authenticate) and
407  *	as an event on the "mlme" multicast group indicating completion of the
408  *	authentication process.
409  *	When used as a command, %NL80211_ATTR_IFINDEX is used to identify the
410  *	interface. %NL80211_ATTR_MAC is used to specify PeerSTAAddress (and
411  *	BSSID in case of station mode). %NL80211_ATTR_SSID is used to specify
412  *	the SSID (mainly for association, but is included in authentication
413  *	request, too, to help BSS selection. %NL80211_ATTR_WIPHY_FREQ is used
414  *	to specify the frequence of the channel in MHz. %NL80211_ATTR_AUTH_TYPE
415  *	is used to specify the authentication type. %NL80211_ATTR_IE is used to
416  *	define IEs (VendorSpecificInfo, but also including RSN IE and FT IEs)
417  *	to be added to the frame.
418  *	When used as an event, this reports reception of an Authentication
419  *	frame in station and IBSS modes when the local MLME processed the
420  *	frame, i.e., it was for the local STA and was received in correct
421  *	state. This is similar to MLME-AUTHENTICATE.confirm primitive in the
422  *	MLME SAP interface (kernel providing MLME, userspace SME). The
423  *	included %NL80211_ATTR_FRAME attribute contains the management frame
424  *	(including both the header and frame body, but not FCS). This event is
425  *	also used to indicate if the authentication attempt timed out. In that
426  *	case the %NL80211_ATTR_FRAME attribute is replaced with a
427  *	%NL80211_ATTR_TIMED_OUT flag (and %NL80211_ATTR_MAC to indicate which
428  *	pending authentication timed out).
429  * @NL80211_CMD_ASSOCIATE: association request and notification; like
430  *	NL80211_CMD_AUTHENTICATE but for Association and Reassociation
431  *	(similar to MLME-ASSOCIATE.request, MLME-REASSOCIATE.request,
432  *	MLME-ASSOCIATE.confirm or MLME-REASSOCIATE.confirm primitives). The
433  *	%NL80211_ATTR_PREV_BSSID attribute is used to specify whether the
434  *	request is for the initial association to an ESS (that attribute not
435  *	included) or for reassociation within the ESS (that attribute is
436  *	included).
437  * @NL80211_CMD_DEAUTHENTICATE: deauthentication request and notification; like
438  *	NL80211_CMD_AUTHENTICATE but for Deauthentication frames (similar to
439  *	MLME-DEAUTHENTICATION.request and MLME-DEAUTHENTICATE.indication
440  *	primitives).
441  * @NL80211_CMD_DISASSOCIATE: disassociation request and notification; like
442  *	NL80211_CMD_AUTHENTICATE but for Disassociation frames (similar to
443  *	MLME-DISASSOCIATE.request and MLME-DISASSOCIATE.indication primitives).
444  *
445  * @NL80211_CMD_MICHAEL_MIC_FAILURE: notification of a locally detected Michael
446  *	MIC (part of TKIP) failure; sent on the "mlme" multicast group; the
447  *	event includes %NL80211_ATTR_MAC to describe the source MAC address of
448  *	the frame with invalid MIC, %NL80211_ATTR_KEY_TYPE to show the key
449  *	type, %NL80211_ATTR_KEY_IDX to indicate the key identifier, and
450  *	%NL80211_ATTR_KEY_SEQ to indicate the TSC value of the frame; this
451  *	event matches with MLME-MICHAELMICFAILURE.indication() primitive
452  *
453  * @NL80211_CMD_JOIN_IBSS: Join a new IBSS -- given at least an SSID and a
454  *	FREQ attribute (for the initial frequency if no peer can be found)
455  *	and optionally a MAC (as BSSID) and FREQ_FIXED attribute if those
456  *	should be fixed rather than automatically determined. Can only be
457  *	executed on a network interface that is UP, and fixed BSSID/FREQ
458  *	may be rejected. Another optional parameter is the beacon interval,
459  *	given in the %NL80211_ATTR_BEACON_INTERVAL attribute, which if not
460  *	given defaults to 100 TU (102.4ms).
461  * @NL80211_CMD_LEAVE_IBSS: Leave the IBSS -- no special arguments, the IBSS is
462  *	determined by the network interface.
463  *
464  * @NL80211_CMD_TESTMODE: testmode command, takes a wiphy (or ifindex) attribute
465  *	to identify the device, and the TESTDATA blob attribute to pass through
466  *	to the driver.
467  *
468  * @NL80211_CMD_CONNECT: connection request and notification; this command
469  *	requests to connect to a specified network but without separating
470  *	auth and assoc steps. For this, you need to specify the SSID in a
471  *	%NL80211_ATTR_SSID attribute, and can optionally specify the association
472  *	IEs in %NL80211_ATTR_IE, %NL80211_ATTR_AUTH_TYPE, %NL80211_ATTR_USE_MFP,
473  *	%NL80211_ATTR_MAC, %NL80211_ATTR_WIPHY_FREQ, %NL80211_ATTR_CONTROL_PORT,
474  *	%NL80211_ATTR_CONTROL_PORT_ETHERTYPE,
475  *	%NL80211_ATTR_CONTROL_PORT_NO_ENCRYPT, %NL80211_ATTR_MAC_HINT, and
476  *	%NL80211_ATTR_WIPHY_FREQ_HINT.
477  *	If included, %NL80211_ATTR_MAC and %NL80211_ATTR_WIPHY_FREQ are
478  *	restrictions on BSS selection, i.e., they effectively prevent roaming
479  *	within the ESS. %NL80211_ATTR_MAC_HINT and %NL80211_ATTR_WIPHY_FREQ_HINT
480  *	can be included to provide a recommendation of the initial BSS while
481  *	allowing the driver to roam to other BSSes within the ESS and also to
482  *	ignore this recommendation if the indicated BSS is not ideal. Only one
483  *	set of BSSID,frequency parameters is used (i.e., either the enforcing
484  *	%NL80211_ATTR_MAC,%NL80211_ATTR_WIPHY_FREQ or the less strict
485  *	%NL80211_ATTR_MAC_HINT and %NL80211_ATTR_WIPHY_FREQ_HINT).
486  *	%NL80211_ATTR_PREV_BSSID can be used to request a reassociation within
487  *	the ESS in case the device is already associated and an association with
488  *	a different BSS is desired.
489  *	Background scan period can optionally be
490  *	specified in %NL80211_ATTR_BG_SCAN_PERIOD,
491  *	if not specified default background scan configuration
492  *	in driver is used and if period value is 0, bg scan will be disabled.
493  *	This attribute is ignored if driver does not support roam scan.
494  *	It is also sent as an event, with the BSSID and response IEs when the
495  *	connection is established or failed to be established. This can be
496  *	determined by the STATUS_CODE attribute.
497  * @NL80211_CMD_ROAM: request that the card roam (currently not implemented),
498  *	sent as an event when the card/driver roamed by itself.
499  * @NL80211_CMD_DISCONNECT: drop a given connection; also used to notify
500  *	userspace that a connection was dropped by the AP or due to other
501  *	reasons, for this the %NL80211_ATTR_DISCONNECTED_BY_AP and
502  *	%NL80211_ATTR_REASON_CODE attributes are used.
503  *
504  * @NL80211_CMD_SET_WIPHY_NETNS: Set a wiphy's netns. Note that all devices
505  *	associated with this wiphy must be down and will follow.
506  *
507  * @NL80211_CMD_REMAIN_ON_CHANNEL: Request to remain awake on the specified
508  *	channel for the specified amount of time. This can be used to do
509  *	off-channel operations like transmit a Public Action frame and wait for
510  *	a response while being associated to an AP on another channel.
511  *	%NL80211_ATTR_IFINDEX is used to specify which interface (and thus
512  *	radio) is used. %NL80211_ATTR_WIPHY_FREQ is used to specify the
513  *	frequency for the operation.
514  *	%NL80211_ATTR_DURATION is used to specify the duration in milliseconds
515  *	to remain on the channel. This command is also used as an event to
516  *	notify when the requested duration starts (it may take a while for the
517  *	driver to schedule this time due to other concurrent needs for the
518  *	radio).
519  *	When called, this operation returns a cookie (%NL80211_ATTR_COOKIE)
520  *	that will be included with any events pertaining to this request;
521  *	the cookie is also used to cancel the request.
522  * @NL80211_CMD_CANCEL_REMAIN_ON_CHANNEL: This command can be used to cancel a
523  *	pending remain-on-channel duration if the desired operation has been
524  *	completed prior to expiration of the originally requested duration.
525  *	%NL80211_ATTR_WIPHY or %NL80211_ATTR_IFINDEX is used to specify the
526  *	radio. The %NL80211_ATTR_COOKIE attribute must be given as well to
527  *	uniquely identify the request.
528  *	This command is also used as an event to notify when a requested
529  *	remain-on-channel duration has expired.
530  *
531  * @NL80211_CMD_SET_TX_BITRATE_MASK: Set the mask of rates to be used in TX
532  *	rate selection. %NL80211_ATTR_IFINDEX is used to specify the interface
533  *	and @NL80211_ATTR_TX_RATES the set of allowed rates.
534  *
535  * @NL80211_CMD_REGISTER_FRAME: Register for receiving certain mgmt frames
536  *	(via @NL80211_CMD_FRAME) for processing in userspace. This command
537  *	requires an interface index, a frame type attribute (optional for
538  *	backward compatibility reasons, if not given assumes action frames)
539  *	and a match attribute containing the first few bytes of the frame
540  *	that should match, e.g. a single byte for only a category match or
541  *	four bytes for vendor frames including the OUI. The registration
542  *	cannot be dropped, but is removed automatically when the netlink
543  *	socket is closed. Multiple registrations can be made.
544  * @NL80211_CMD_REGISTER_ACTION: Alias for @NL80211_CMD_REGISTER_FRAME for
545  *	backward compatibility
546  * @NL80211_CMD_FRAME: Management frame TX request and RX notification. This
547  *	command is used both as a request to transmit a management frame and
548  *	as an event indicating reception of a frame that was not processed in
549  *	kernel code, but is for us (i.e., which may need to be processed in a
550  *	user space application). %NL80211_ATTR_FRAME is used to specify the
551  *	frame contents (including header). %NL80211_ATTR_WIPHY_FREQ is used
552  *	to indicate on which channel the frame is to be transmitted or was
553  *	received. If this channel is not the current channel (remain-on-channel
554  *	or the operational channel) the device will switch to the given channel
555  *	and transmit the frame, optionally waiting for a response for the time
556  *	specified using %NL80211_ATTR_DURATION. When called, this operation
557  *	returns a cookie (%NL80211_ATTR_COOKIE) that will be included with the
558  *	TX status event pertaining to the TX request.
559  *	%NL80211_ATTR_TX_NO_CCK_RATE is used to decide whether to send the
560  *	management frames at CCK rate or not in 2GHz band.
561  *	%NL80211_ATTR_CSA_C_OFFSETS_TX is an array of offsets to CSA
562  *	counters which will be updated to the current value. This attribute
563  *	is used during CSA period.
564  * @NL80211_CMD_FRAME_WAIT_CANCEL: When an off-channel TX was requested, this
565  *	command may be used with the corresponding cookie to cancel the wait
566  *	time if it is known that it is no longer necessary.
567  * @NL80211_CMD_ACTION: Alias for @NL80211_CMD_FRAME for backward compatibility.
568  * @NL80211_CMD_FRAME_TX_STATUS: Report TX status of a management frame
569  *	transmitted with %NL80211_CMD_FRAME. %NL80211_ATTR_COOKIE identifies
570  *	the TX command and %NL80211_ATTR_FRAME includes the contents of the
571  *	frame. %NL80211_ATTR_ACK flag is included if the recipient acknowledged
572  *	the frame.
573  * @NL80211_CMD_ACTION_TX_STATUS: Alias for @NL80211_CMD_FRAME_TX_STATUS for
574  *	backward compatibility.
575  *
576  * @NL80211_CMD_SET_POWER_SAVE: Set powersave, using %NL80211_ATTR_PS_STATE
577  * @NL80211_CMD_GET_POWER_SAVE: Get powersave status in %NL80211_ATTR_PS_STATE
578  *
579  * @NL80211_CMD_SET_CQM: Connection quality monitor configuration. This command
580  *	is used to configure connection quality monitoring notification trigger
581  *	levels.
582  * @NL80211_CMD_NOTIFY_CQM: Connection quality monitor notification. This
583  *	command is used as an event to indicate the that a trigger level was
584  *	reached.
585  * @NL80211_CMD_SET_CHANNEL: Set the channel (using %NL80211_ATTR_WIPHY_FREQ
586  *	and the attributes determining channel width) the given interface
587  *	(identifed by %NL80211_ATTR_IFINDEX) shall operate on.
588  *	In case multiple channels are supported by the device, the mechanism
589  *	with which it switches channels is implementation-defined.
590  *	When a monitor interface is given, it can only switch channel while
591  *	no other interfaces are operating to avoid disturbing the operation
592  *	of any other interfaces, and other interfaces will again take
593  *	precedence when they are used.
594  *
595  * @NL80211_CMD_SET_WDS_PEER: Set the MAC address of the peer on a WDS interface.
596  *
597  * @NL80211_CMD_JOIN_MESH: Join a mesh. The mesh ID must be given, and initial
598  *	mesh config parameters may be given.
599  * @NL80211_CMD_LEAVE_MESH: Leave the mesh network -- no special arguments, the
600  *	network is determined by the network interface.
601  *
602  * @NL80211_CMD_UNPROT_DEAUTHENTICATE: Unprotected deauthentication frame
603  *	notification. This event is used to indicate that an unprotected
604  *	deauthentication frame was dropped when MFP is in use.
605  * @NL80211_CMD_UNPROT_DISASSOCIATE: Unprotected disassociation frame
606  *	notification. This event is used to indicate that an unprotected
607  *	disassociation frame was dropped when MFP is in use.
608  *
609  * @NL80211_CMD_NEW_PEER_CANDIDATE: Notification on the reception of a
610  *      beacon or probe response from a compatible mesh peer.  This is only
611  *      sent while no station information (sta_info) exists for the new peer
612  *      candidate and when @NL80211_MESH_SETUP_USERSPACE_AUTH,
613  *      @NL80211_MESH_SETUP_USERSPACE_AMPE, or
614  *      @NL80211_MESH_SETUP_USERSPACE_MPM is set.  On reception of this
615  *      notification, userspace may decide to create a new station
616  *      (@NL80211_CMD_NEW_STATION).  To stop this notification from
617  *      reoccurring, the userspace authentication daemon may want to create the
618  *      new station with the AUTHENTICATED flag unset and maybe change it later
619  *      depending on the authentication result.
620  *
621  * @NL80211_CMD_GET_WOWLAN: get Wake-on-Wireless-LAN (WoWLAN) settings.
622  * @NL80211_CMD_SET_WOWLAN: set Wake-on-Wireless-LAN (WoWLAN) settings.
623  *	Since wireless is more complex than wired ethernet, it supports
624  *	various triggers. These triggers can be configured through this
625  *	command with the %NL80211_ATTR_WOWLAN_TRIGGERS attribute. For
626  *	more background information, see
627  *	http://wireless.kernel.org/en/users/Documentation/WoWLAN.
628  *	The @NL80211_CMD_SET_WOWLAN command can also be used as a notification
629  *	from the driver reporting the wakeup reason. In this case, the
630  *	@NL80211_ATTR_WOWLAN_TRIGGERS attribute will contain the reason
631  *	for the wakeup, if it was caused by wireless. If it is not present
632  *	in the wakeup notification, the wireless device didn't cause the
633  *	wakeup but reports that it was woken up.
634  *
635  * @NL80211_CMD_SET_REKEY_OFFLOAD: This command is used give the driver
636  *	the necessary information for supporting GTK rekey offload. This
637  *	feature is typically used during WoWLAN. The configuration data
638  *	is contained in %NL80211_ATTR_REKEY_DATA (which is nested and
639  *	contains the data in sub-attributes). After rekeying happened,
640  *	this command may also be sent by the driver as an MLME event to
641  *	inform userspace of the new replay counter.
642  *
643  * @NL80211_CMD_PMKSA_CANDIDATE: This is used as an event to inform userspace
644  *	of PMKSA caching dandidates.
645  *
646  * @NL80211_CMD_TDLS_OPER: Perform a high-level TDLS command (e.g. link setup).
647  *	In addition, this can be used as an event to request userspace to take
648  *	actions on TDLS links (set up a new link or tear down an existing one).
649  *	In such events, %NL80211_ATTR_TDLS_OPERATION indicates the requested
650  *	operation, %NL80211_ATTR_MAC contains the peer MAC address, and
651  *	%NL80211_ATTR_REASON_CODE the reason code to be used (only with
652  *	%NL80211_TDLS_TEARDOWN).
653  * @NL80211_CMD_TDLS_MGMT: Send a TDLS management frame. The
654  *	%NL80211_ATTR_TDLS_ACTION attribute determines the type of frame to be
655  *	sent. Public Action codes (802.11-2012 8.1.5.1) will be sent as
656  *	802.11 management frames, while TDLS action codes (802.11-2012
657  *	8.5.13.1) will be encapsulated and sent as data frames. The currently
658  *	supported Public Action code is %WLAN_PUB_ACTION_TDLS_DISCOVER_RES
659  *	and the currently supported TDLS actions codes are given in
660  *	&enum ieee80211_tdls_actioncode.
661  *
662  * @NL80211_CMD_UNEXPECTED_FRAME: Used by an application controlling an AP
663  *	(or GO) interface (i.e. hostapd) to ask for unexpected frames to
664  *	implement sending deauth to stations that send unexpected class 3
665  *	frames. Also used as the event sent by the kernel when such a frame
666  *	is received.
667  *	For the event, the %NL80211_ATTR_MAC attribute carries the TA and
668  *	other attributes like the interface index are present.
669  *	If used as the command it must have an interface index and you can
670  *	only unsubscribe from the event by closing the socket. Subscription
671  *	is also for %NL80211_CMD_UNEXPECTED_4ADDR_FRAME events.
672  *
673  * @NL80211_CMD_UNEXPECTED_4ADDR_FRAME: Sent as an event indicating that the
674  *	associated station identified by %NL80211_ATTR_MAC sent a 4addr frame
675  *	and wasn't already in a 4-addr VLAN. The event will be sent similarly
676  *	to the %NL80211_CMD_UNEXPECTED_FRAME event, to the same listener.
677  *
678  * @NL80211_CMD_PROBE_CLIENT: Probe an associated station on an AP interface
679  *	by sending a null data frame to it and reporting when the frame is
680  *	acknowleged. This is used to allow timing out inactive clients. Uses
681  *	%NL80211_ATTR_IFINDEX and %NL80211_ATTR_MAC. The command returns a
682  *	direct reply with an %NL80211_ATTR_COOKIE that is later used to match
683  *	up the event with the request. The event includes the same data and
684  *	has %NL80211_ATTR_ACK set if the frame was ACKed.
685  *
686  * @NL80211_CMD_REGISTER_BEACONS: Register this socket to receive beacons from
687  *	other BSSes when any interfaces are in AP mode. This helps implement
688  *	OLBC handling in hostapd. Beacons are reported in %NL80211_CMD_FRAME
689  *	messages. Note that per PHY only one application may register.
690  *
691  * @NL80211_CMD_SET_NOACK_MAP: sets a bitmap for the individual TIDs whether
692  *      No Acknowledgement Policy should be applied.
693  *
694  * @NL80211_CMD_CH_SWITCH_NOTIFY: An AP or GO may decide to switch channels
695  *	independently of the userspace SME, send this event indicating
696  *	%NL80211_ATTR_IFINDEX is now on %NL80211_ATTR_WIPHY_FREQ and the
697  *	attributes determining channel width.  This indication may also be
698  *	sent when a remotely-initiated switch (e.g., when a STA receives a CSA
699  *	from the remote AP) is completed;
700  *
701  * @NL80211_CMD_CH_SWITCH_STARTED_NOTIFY: Notify that a channel switch
702  *	has been started on an interface, regardless of the initiator
703  *	(ie. whether it was requested from a remote device or
704  *	initiated on our own).  It indicates that
705  *	%NL80211_ATTR_IFINDEX will be on %NL80211_ATTR_WIPHY_FREQ
706  *	after %NL80211_ATTR_CH_SWITCH_COUNT TBTT's.  The userspace may
707  *	decide to react to this indication by requesting other
708  *	interfaces to change channel as well.
709  *
710  * @NL80211_CMD_START_P2P_DEVICE: Start the given P2P Device, identified by
711  *	its %NL80211_ATTR_WDEV identifier. It must have been created with
712  *	%NL80211_CMD_NEW_INTERFACE previously. After it has been started, the
713  *	P2P Device can be used for P2P operations, e.g. remain-on-channel and
714  *	public action frame TX.
715  * @NL80211_CMD_STOP_P2P_DEVICE: Stop the given P2P Device, identified by
716  *	its %NL80211_ATTR_WDEV identifier.
717  *
718  * @NL80211_CMD_CONN_FAILED: connection request to an AP failed; used to
719  *	notify userspace that AP has rejected the connection request from a
720  *	station, due to particular reason. %NL80211_ATTR_CONN_FAILED_REASON
721  *	is used for this.
722  *
723  * @NL80211_CMD_SET_MCAST_RATE: Change the rate used to send multicast frames
724  *	for IBSS or MESH vif.
725  *
726  * @NL80211_CMD_SET_MAC_ACL: sets ACL for MAC address based access control.
727  *	This is to be used with the drivers advertising the support of MAC
728  *	address based access control. List of MAC addresses is passed in
729  *	%NL80211_ATTR_MAC_ADDRS and ACL policy is passed in
730  *	%NL80211_ATTR_ACL_POLICY. Driver will enable ACL with this list, if it
731  *	is not already done. The new list will replace any existing list. Driver
732  *	will clear its ACL when the list of MAC addresses passed is empty. This
733  *	command is used in AP/P2P GO mode. Driver has to make sure to clear its
734  *	ACL list during %NL80211_CMD_STOP_AP.
735  *
736  * @NL80211_CMD_RADAR_DETECT: Start a Channel availability check (CAC). Once
737  *	a radar is detected or the channel availability scan (CAC) has finished
738  *	or was aborted, or a radar was detected, usermode will be notified with
739  *	this event. This command is also used to notify userspace about radars
740  *	while operating on this channel.
741  *	%NL80211_ATTR_RADAR_EVENT is used to inform about the type of the
742  *	event.
743  *
744  * @NL80211_CMD_GET_PROTOCOL_FEATURES: Get global nl80211 protocol features,
745  *	i.e. features for the nl80211 protocol rather than device features.
746  *	Returns the features in the %NL80211_ATTR_PROTOCOL_FEATURES bitmap.
747  *
748  * @NL80211_CMD_UPDATE_FT_IES: Pass down the most up-to-date Fast Transition
749  *	Information Element to the WLAN driver
750  *
751  * @NL80211_CMD_FT_EVENT: Send a Fast transition event from the WLAN driver
752  *	to the supplicant. This will carry the target AP's MAC address along
753  *	with the relevant Information Elements. This event is used to report
754  *	received FT IEs (MDIE, FTIE, RSN IE, TIE, RICIE).
755  *
756  * @NL80211_CMD_CRIT_PROTOCOL_START: Indicates user-space will start running
757  *	a critical protocol that needs more reliability in the connection to
758  *	complete.
759  *
760  * @NL80211_CMD_CRIT_PROTOCOL_STOP: Indicates the connection reliability can
761  *	return back to normal.
762  *
763  * @NL80211_CMD_GET_COALESCE: Get currently supported coalesce rules.
764  * @NL80211_CMD_SET_COALESCE: Configure coalesce rules or clear existing rules.
765  *
766  * @NL80211_CMD_CHANNEL_SWITCH: Perform a channel switch by announcing the
767  *	the new channel information (Channel Switch Announcement - CSA)
768  *	in the beacon for some time (as defined in the
769  *	%NL80211_ATTR_CH_SWITCH_COUNT parameter) and then change to the
770  *	new channel. Userspace provides the new channel information (using
771  *	%NL80211_ATTR_WIPHY_FREQ and the attributes determining channel
772  *	width). %NL80211_ATTR_CH_SWITCH_BLOCK_TX may be supplied to inform
773  *	other station that transmission must be blocked until the channel
774  *	switch is complete.
775  *
776  * @NL80211_CMD_VENDOR: Vendor-specified command/event. The command is specified
777  *	by the %NL80211_ATTR_VENDOR_ID attribute and a sub-command in
778  *	%NL80211_ATTR_VENDOR_SUBCMD. Parameter(s) can be transported in
779  *	%NL80211_ATTR_VENDOR_DATA.
780  *	For feature advertisement, the %NL80211_ATTR_VENDOR_DATA attribute is
781  *	used in the wiphy data as a nested attribute containing descriptions
782  *	(&struct nl80211_vendor_cmd_info) of the supported vendor commands.
783  *	This may also be sent as an event with the same attributes.
784  *
785  * @NL80211_CMD_SET_QOS_MAP: Set Interworking QoS mapping for IP DSCP values.
786  *	The QoS mapping information is included in %NL80211_ATTR_QOS_MAP. If
787  *	that attribute is not included, QoS mapping is disabled. Since this
788  *	QoS mapping is relevant for IP packets, it is only valid during an
789  *	association. This is cleared on disassociation and AP restart.
790  *
791  * @NL80211_CMD_ADD_TX_TS: Ask the kernel to add a traffic stream for the given
792  *	%NL80211_ATTR_TSID and %NL80211_ATTR_MAC with %NL80211_ATTR_USER_PRIO
793  *	and %NL80211_ATTR_ADMITTED_TIME parameters.
794  *	Note that the action frame handshake with the AP shall be handled by
795  *	userspace via the normal management RX/TX framework, this only sets
796  *	up the TX TS in the driver/device.
797  *	If the admitted time attribute is not added then the request just checks
798  *	if a subsequent setup could be successful, the intent is to use this to
799  *	avoid setting up a session with the AP when local restrictions would
800  *	make that impossible. However, the subsequent "real" setup may still
801  *	fail even if the check was successful.
802  * @NL80211_CMD_DEL_TX_TS: Remove an existing TS with the %NL80211_ATTR_TSID
803  *	and %NL80211_ATTR_MAC parameters. It isn't necessary to call this
804  *	before removing a station entry entirely, or before disassociating
805  *	or similar, cleanup will happen in the driver/device in this case.
806  *
807  * @NL80211_CMD_GET_MPP: Get mesh path attributes for mesh proxy path to
808  *	destination %NL80211_ATTR_MAC on the interface identified by
809  *	%NL80211_ATTR_IFINDEX.
810  *
811  * @NL80211_CMD_JOIN_OCB: Join the OCB network. The center frequency and
812  *	bandwidth of a channel must be given.
813  * @NL80211_CMD_LEAVE_OCB: Leave the OCB network -- no special arguments, the
814  *	network is determined by the network interface.
815  *
816  * @NL80211_CMD_TDLS_CHANNEL_SWITCH: Start channel-switching with a TDLS peer,
817  *	identified by the %NL80211_ATTR_MAC parameter. A target channel is
818  *	provided via %NL80211_ATTR_WIPHY_FREQ and other attributes determining
819  *	channel width/type. The target operating class is given via
820  *	%NL80211_ATTR_OPER_CLASS.
821  *	The driver is responsible for continually initiating channel-switching
822  *	operations and returning to the base channel for communication with the
823  *	AP.
824  * @NL80211_CMD_TDLS_CANCEL_CHANNEL_SWITCH: Stop channel-switching with a TDLS
825  *	peer given by %NL80211_ATTR_MAC. Both peers must be on the base channel
826  *	when this command completes.
827  *
828  * @NL80211_CMD_WIPHY_REG_CHANGE: Similar to %NL80211_CMD_REG_CHANGE, but used
829  *	as an event to indicate changes for devices with wiphy-specific regdom
830  *	management.
831  *
832  * @NL80211_CMD_ABORT_SCAN: Stop an ongoing scan. Returns -ENOENT if a scan is
833  *	not running. The driver indicates the status of the scan through
834  *	cfg80211_scan_done().
835  *
836  * @NL80211_CMD_MAX: highest used command number
837  * @__NL80211_CMD_AFTER_LAST: internal use

1415  *	nl80211 capability flag.
1416  *
1417  * @NL80211_ATTR_BSS_HT_OPMODE: HT operation mode (u16)

1424  *	changed once the mesh is active.
1425  * @NL80211_ATTR_MESH_CONFIG: Mesh configuration parameters, a nested attribute
1426  *	containing attributes from &enum nl80211_meshconf_params.
1427  * @NL80211_ATTR_SUPPORT_MESH_AUTH: Currently, this means the underlying driver
1428  *	allows auth frames in a mesh to be passed to userspace for processing via
1429  *	the @NL80211_MESH_SETUP_USERSPACE_AUTH flag.
1430  * @NL80211_ATTR_STA_PLINK_STATE: The state of a mesh peer link as defined in

1447  *	that match any of the sets will be reported.  These are
1448  *	pass-thru filter rules.
1449  *	For a match to succeed, the BSS must match all attributes of a
1450  *	set.  Since not every hardware supports matching all types of
1451  *	attributes, there is no guarantee that the reported BSSs are
1452  *	fully complying with the match sets and userspace needs to be
1453  *	able to ignore them by itself.
1454  *	Thus, the implementation is somewhat hardware-dependent, but
1455  *	this is only an optimization and the userspace application
1456  *	needs to handle all the non-filtered results anyway.
1457  *	If the match attributes don't make sense when combined with
1458  *	the values passed in @NL80211_ATTR_SCAN_SSIDS (eg. if an SSID
1459  *	is included in the probe request, but the match attributes

1530  * @NL80211_ATTR_DONT_WAIT_FOR_ACK: Used with %NL80211_CMD_FRAME, this tells
1531  *	the driver to not wait for an acknowledgement. Note that due to this,
1532  *	it will also not give a status callback nor return a cookie. This is

1748  * @NL80211_ATTR_WIPHY_DYN_ACK: flag attribute used to enable ACK timeout
1749  *	estimation algorithm (dynack). In order to activate dynack
1750  *	%NL80211_FEATURE_ACKTO_ESTIMATION feature flag must be set by lower
1751  *	drivers to indicate dynack capability. Dynack is automatically disabled
1752  *	setting valid value for coverage class.
1753  *
1754  * @NL80211_ATTR_TSID: a TSID value (u8 attribute)
1755  * @NL80211_ATTR_USER_PRIO: user priority value (u8 attribute)

1761  *
1762  * @NL80211_ATTR_OPER_CLASS: operating class
1763  *
1764  * @NL80211_ATTR_MAC_MASK: MAC address mask
1765  *
1766  * @NL80211_ATTR_WIPHY_SELF_MANAGED_REG: flag attribute indicating this device
1767  *	is self-managing its regulatory information and any regulatory domain
1768  *	obtained from it is coming from the device's wiphy and not the global
1769  *	cfg80211 regdomain.
1770  *
1771  * @NL80211_ATTR_EXT_FEATURES: extended feature flags contained in a byte
1772  *	array. The feature flags are identified by their bit index (see &enum
1773  *	nl80211_ext_feature_index). The bit index is ordered starting at the
1774  *	least-significant bit of the first byte in the array, ie. bit index 0
1775  *	is located at bit 0 of byte 0. bit index 25 would be located at bit 1
1776  *	of byte 3 (u8 array).
1777  *
1778  * @NL80211_ATTR_SURVEY_RADIO_STATS: Request overall radio statistics to be
1779  *	returned along with other survey data. If set, @NL80211_CMD_GET_SURVEY
1780  *	may return a survey entry without a channel indicating global radio
1781  *	statistics (only some values are valid and make sense.)
1782  *	For devices that don't return such an entry even then, the information
1783  *	should be contained in the result as the sum of the respective counters
1784  *	over all channels.
1785  *
1786  * @NL80211_ATTR_SCHED_SCAN_DELAY: delay before the first cycle of a
1787  *	scheduled scan is started.  Or the delay before a WoWLAN
1788  *	net-detect scan is started, counting from the moment the
1789  *	system is suspended.  This value is a u32, in seconds.
1790 
1791  * @NL80211_ATTR_REG_INDOOR: flag attribute, if set indicates that the device
1792  *      is operating in an indoor environment.
1793  *
1794  * @NL80211_ATTR_MAX_NUM_SCHED_SCAN_PLANS: maximum number of scan plans for
1795  *	scheduled scan supported by the device (u32), a wiphy attribute.
1796  * @NL80211_ATTR_MAX_SCAN_PLAN_INTERVAL: maximum interval (in seconds) for
1797  *	a scan plan (u32), a wiphy attribute.
1798  * @NL80211_ATTR_MAX_SCAN_PLAN_ITERATIONS: maximum number of iterations in
1799  *	a scan plan (u32), a wiphy attribute.
1800  * @NL80211_ATTR_SCHED_SCAN_PLANS: a list of scan plans for scheduled scan.
1801  *	Each scan plan defines the number of scan iterations and the interval
1802  *	between scans. The last scan plan will always run infinitely,
1803  *	thus it must not specify the number of iterations, only the interval
1804  *	between scans. The scan plans are executed sequentially.
1805  *	Each scan plan is a nested attribute of &enum nl80211_sched_scan_plan.
1806  * @NL80211_ATTR_PBSS: flag attribute. If set it means operate
1807  *	in a PBSS. Specified in %NL80211_CMD_CONNECT to request
1808  *	connecting to a PCP, and in %NL80211_CMD_START_AP to start
1809  *	a PCP instead of AP. Relevant for DMG networks only.
1810  * @NL80211_ATTR_BSS_SELECT: nested attribute for driver supporting the
1811  *	BSS selection feature. When used with %NL80211_CMD_GET_WIPHY it contains
1812  *	attributes according &enum nl80211_bss_select_attr to indicate what
1813  *	BSS selection behaviours are supported. When used with %NL80211_CMD_CONNECT
1814  *	it contains the behaviour-specific attribute containing the parameters for
1815  *	BSS selection to be done by driver and/or firmware.
1816  *
1817  * @NL80211_ATTR_STA_SUPPORT_P2P_PS: whether P2P PS mechanism supported
1818  *	or not. u8, one of the values of &enum nl80211_sta_p2p_ps_status
1819  *
1820  * @NL80211_ATTR_PAD: attribute used for padding for 64-bit alignment
1821  *
1822  * @NUM_NL80211_ATTR: total number of nl80211_attrs available

3940  * DOC: TCP connection wakeup
3941  *
3942  * Some devices can establish a TCP connection in order to be woken up by a
3943  * packet coming in from outside their network segment, or behind NAT. If
3944  * configured, the device will establish a TCP connection to the given
3945  * service, and periodically send data to that service. The first data
3946  * packet is usually transmitted after SYN/ACK, also ACKing the SYN/ACK.
3947  * The data packets can optionally include a (little endian) sequence
3948  * number (in the TCP payload!) that is generated by the device, and, also
3949  * optionally, a token from a list of tokens. This serves as a keep-alive
3950  * with the service, and for NATed connections, etc.
3951  *
3952  * During this keep-alive period, the server doesn't send any data to the
3953  * client. When receiving data, it is compared against the wakeup pattern
3954  * (and mask) and if it matches, the host is woken up. Similarly, if the
3955  * connection breaks or cannot be established to start with, the host is
3956  * also woken up.
3957  *
3958  * Developer's note: ARP offload is required for this, otherwise TCP
3959  * response packets might not go through correctly.

4338  *	socket option.
4339  * @NL80211_FEATURE_HT_IBSS: This driver supports IBSS with HT datarates.
4340  * @NL80211_FEATURE_INACTIVITY_TIMER: This driver takes care of freeing up
4341  *	the connected inactive stations in AP mode.
4342  * @NL80211_FEATURE_CELL_BASE_REG_HINTS: This driver has been tested
4343  *	to work properly to suppport receiving regulatory hints from
4344  *	cellular base stations.
4345  * @NL80211_FEATURE_P2P_DEVICE_NEEDS_CHANNEL: (no longer available, only
4346  *	here to reserve the value for API/ABI compatibility)
4347  * @NL80211_FEATURE_SAE: This driver supports simultaneous authentication of
4348  *	equals (SAE) with user space SME (NL80211_CMD_AUTHENTICATE) in station
4349  *	mode
4350  * @NL80211_FEATURE_LOW_PRIORITY_SCAN: This driver supports low priority scan
4351  * @NL80211_FEATURE_SCAN_FLUSH: Scan flush is supported

4353  * @NL80211_FEATURE_VIF_TXPOWER: The driver supports per-vif TX power setting
4354  * @NL80211_FEATURE_NEED_OBSS_SCAN: The driver expects userspace to perform
4355  *	OBSS scans and generate 20/40 BSS coex reports. This flag is used only
4356  *	for drivers implementing the CONNECT API, for AUTH/ASSOC it is implied.
4357  * @NL80211_FEATURE_P2P_GO_CTWIN: P2P GO implementation supports CT Window
4358  *	setting

4361  * @NL80211_FEATURE_FULL_AP_CLIENT_STATE: The driver supports full state
4362  *	transitions for AP clients. Without this flag (and if the driver
4363  *	doesn't have the AP SME in the device) the driver supports adding
4364  *	stations only when they're associated and adds them in associated
4365  *	state (to later be transitioned into authorized), with this flag
4366  *	they should be added before even sending the authentication reply
4367  *	and then transitioned into authenticated, associated and authorized
4368  *	states using station flags.
4369  *	Note that even for drivers that support this, the default is to add
4370  *	stations in authenticated/associated state, so to add unauthenticated
4371  *	stations the authenticated/associated bits have to be set in the mask.
4372  * @NL80211_FEATURE_ADVERTISE_CHAN_LIMITS: cfg80211 advertises channel limits

4375  *	Peering Management entity which may be implemented by registering for
4376  *	beacons or NL80211_CMD_NEW_PEER_CANDIDATE events. The mesh beacon is
4377  *	still generated by the driver.
4378  * @NL80211_FEATURE_ACTIVE_MONITOR: This driver supports an active monitor
4379  *	interface. An active monitor interface behaves like a normal monitor
4380  *	interface, but gets added to the driver. It ensures that incoming
4381  *	unicast packets directed at the configured interface address get ACKed.
4382  * @NL80211_FEATURE_AP_MODE_CHAN_WIDTH_CHANGE: This driver supports dynamic
4383  *	channel bandwidth change (e.g., HT 20 <-> 40 MHz channel) during the
4384  *	lifetime of a BSS.
4385  * @NL80211_FEATURE_DS_PARAM_SET_IE_IN_PROBES: This device adds a DS Parameter
4386  *	Set IE to probe requests.
4387  * @NL80211_FEATURE_WFA_TPC_IE_IN_PROBES: This device adds a WFA TPC Report IE
4388  *	to probe requests.
4389  * @NL80211_FEATURE_QUIET: This device, in client mode, supports Quiet Period
4390  *	requests sent to it by an AP.
4391  * @NL80211_FEATURE_TX_POWER_INSERTION: This device is capable of inserting the
4392  *	current tx power value into the TPC Report IE in the spectrum
4393  *	management TPC Report action frame, and in the Radio Measurement Link
4394  *	Measurement Report action frame.
4395  * @NL80211_FEATURE_ACKTO_ESTIMATION: This driver supports dynamic ACK timeout
4396  *	estimation (dynack). %NL80211_ATTR_WIPHY_DYN_ACK flag attribute is used
4397  *	to enable dynack.
4398  * @NL80211_FEATURE_STATIC_SMPS: Device supports static spatial
4399  *	multiplexing powersave, ie. can turn off all but one chain
4400  *	even on HT connections that should be using more chains.
4401  * @NL80211_FEATURE_DYNAMIC_SMPS: Device supports dynamic spatial
4402  *	multiplexing powersave, ie. can turn off all but one chain
4403  *	and then wake the rest up as required after, for example,
4404  *	rts/cts handshake.
4405  * @NL80211_FEATURE_SUPPORTS_WMM_ADMISSION: the device supports setting up WMM
4406  *	TSPEC sessions (TID aka TSID 0-7) with the %NL80211_CMD_ADD_TX_TS
4407  *	command. Standard IEEE 802.11 TSPEC setup is not yet supported, it
4408  *	needs to be able to handle Block-Ack agreements and other things.
4409  * @NL80211_FEATURE_MAC_ON_CREATE: Device supports configuring
4410  *	the vif's MAC address upon creation.
4411  *	See 'macaddr' field in the vif_params (cfg80211.h).

4414  * @NL80211_FEATURE_SCAN_RANDOM_MAC_ADDR: This device/driver supports using a
4415  *	random MAC address during scan (if the device is unassociated); the
4416  *	%NL80211_SCAN_FLAG_RANDOM_ADDR flag may be set for scans and the MAC
4417  *	address mask/value will be used.
4418  * @NL80211_FEATURE_SCHED_SCAN_RANDOM_MAC_ADDR: This device/driver supports
4419  *	using a random MAC address for every scan iteration during scheduled
4420  *	scan (while not associated), the %NL80211_SCAN_FLAG_RANDOM_ADDR may
4421  *	be set for scheduled scan and the MAC address mask/value will be used.
4422  * @NL80211_FEATURE_ND_RANDOM_MAC_ADDR: This device/driver supports using a
4423  *	random MAC address for every scan iteration during "net detect", i.e.
4424  *	scan in unassociated WoWLAN, the %NL80211_SCAN_FLAG_RANDOM_ADDR may
4425  *	be set for scheduled scan and the MAC address mask/value will be used.
