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.

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

1409  * @NL80211_ATTR_SUPPORT_MESH_AUTH: Currently, this means the underlying driver
1410  *	allows auth frames in a mesh to be passed to userspace for processing via
1411  *	the @NL80211_MESH_SETUP_USERSPACE_AUTH flag.
1412  * @NL80211_ATTR_STA_PLINK_STATE: The state of a mesh peer link as defined in
1413  *	&enum nl80211_plink_state. Used when userspace is driving the peer link
1414  *	management state machine.  @NL80211_MESH_SETUP_USERSPACE_AMPE or
1415  *	@NL80211_MESH_SETUP_USERSPACE_MPM must be enabled.

1429  *	that match any of the sets will be reported.  These are
1430  *	pass-thru filter rules.
1431  *	For a match to succeed, the BSS must match all attributes of a
1432  *	set.  Since not every hardware supports matching all types of
1433  *	attributes, there is no guarantee that the reported BSSs are
1434  *	fully complying with the match sets and userspace needs to be
1435  *	able to ignore them by itself.
1436  *	Thus, the implementation is somewhat hardware-dependent, but
1437  *	this is only an optimization and the userspace application
1438  *	needs to handle all the non-filtered results anyway.
1439  *	If the match attributes don't make sense when combined with
1440  *	the values passed in @NL80211_ATTR_SCAN_SSIDS (eg. if an SSID
1441  *	is included in the probe request, but the match attributes

1469  * @NL80211_ATTR_IE_ASSOC_RESP: Information element(s) for (Re)Association
1470  *	Response frames. This is used with %NL80211_CMD_NEW_BEACON and

1511  *
1512  * @NL80211_ATTR_DONT_WAIT_FOR_ACK: Used with %NL80211_CMD_FRAME, this tells
1513  *	the driver to not wait for an acknowledgement. Note that due to this,
1514  *	it will also not give a status callback nor return a cookie. This is
1515  *	mostly useful for probe responses to save airtime.
1516  *
1517  * @NL80211_ATTR_FEATURE_FLAGS: This u32 attribute contains flags from

1753  *	nl80211_ext_feature_index). The bit index is ordered starting at the
1754  *	least-significant bit of the first byte in the array, ie. bit index 0
1755  *	is located at bit 0 of byte 0. bit index 25 would be located at bit 1

1757  *
1758  * @NL80211_ATTR_SURVEY_RADIO_STATS: Request overall radio statistics to be
1759  *	returned along with other survey data. If set, @NL80211_CMD_GET_SURVEY
1760  *	may return a survey entry without a channel indicating global radio
1761  *	statistics (only some values are valid and make sense.)
1762  *	For devices that don't return such an entry even then, the information
1763  *	should be contained in the result as the sum of the respective counters
1764  *	over all channels.

1770  * @NL80211_ATTR_REG_INDOOR: flag attribute, if set indicates that the device
1771  *      is operating in an indoor environment.
1772  *
1773  * @NL80211_ATTR_MAX_NUM_SCHED_SCAN_PLANS: maximum number of scan plans for
1774  *	scheduled scan supported by the device (u32), a wiphy attribute.
1775  * @NL80211_ATTR_MAX_SCAN_PLAN_INTERVAL: maximum interval (in seconds) for

1778  *	a scan plan (u32), a wiphy attribute.
1779  * @NL80211_ATTR_SCHED_SCAN_PLANS: a list of scan plans for scheduled scan.
1780  *	Each scan plan defines the number of scan iterations and the interval
1781  *	between scans. The last scan plan will always run infinitely,
1782  *	thus it must not specify the number of iterations, only the interval
1783  *	between scans. The scan plans are executed sequentially.
1784  *	Each scan plan is a nested attribute of &enum nl80211_sched_scan_plan.

3867  * DOC: TCP connection wakeup
3868  *
3869  * Some devices can establish a TCP connection in order to be woken up by a
3870  * packet coming in from outside their network segment, or behind NAT. If
3871  * configured, the device will establish a TCP connection to the given
3872  * service, and periodically send data to that service. The first data
3873  * packet is usually transmitted after SYN/ACK, also ACKing the SYN/ACK.
3874  * The data packets can optionally include a (little endian) sequence
3875  * number (in the TCP payload!) that is generated by the device, and, also
3876  * optionally, a token from a list of tokens. This serves as a keep-alive
3877  * with the service, and for NATed connections, etc.
3878  *
3879  * During this keep-alive period, the server doesn't send any data to the
3880  * client. When receiving data, it is compared against the wakeup pattern
3881  * (and mask) and if it matches, the host is woken up. Similarly, if the
3882  * connection breaks or cannot be established to start with, the host is
3883  * also woken up.
3884  *
3885  * Developer's note: ARP offload is required for this, otherwise TCP
3886  * response packets might not go through correctly.

4269  * @NL80211_FEATURE_CELL_BASE_REG_HINTS: This driver has been tested

4272  * @NL80211_FEATURE_P2P_DEVICE_NEEDS_CHANNEL: (no longer available, only
4273  *	here to reserve the value for API/ABI compatibility)
4274  * @NL80211_FEATURE_SAE: This driver supports simultaneous authentication of

4280  * @NL80211_FEATURE_VIF_TXPOWER: The driver supports per-vif TX power setting
4281  * @NL80211_FEATURE_NEED_OBSS_SCAN: The driver expects userspace to perform
4282  *	OBSS scans and generate 20/40 BSS coex reports. This flag is used only
4283  *	for drivers implementing the CONNECT API, for AUTH/ASSOC it is implied.

4301  * @NL80211_FEATURE_USERSPACE_MPM: This driver supports a userspace Mesh
4302  *	Peering Management entity which may be implemented by registering for
4303  *	beacons or NL80211_CMD_NEW_PEER_CANDIDATE events. The mesh beacon is
4304  *	still generated by the driver.
4305  * @NL80211_FEATURE_ACTIVE_MONITOR: This driver supports an active monitor
4306  *	interface. An active monitor interface behaves like a normal monitor
4307  *	interface, but gets added to the driver. It ensures that incoming
4308  *	unicast packets directed at the configured interface address get ACKed.
4309  * @NL80211_FEATURE_AP_MODE_CHAN_WIDTH_CHANGE: This driver supports dynamic
4310  *	channel bandwidth change (e.g., HT 20 <-> 40 MHz channel) during the
