40  * DOC: Station handling
41  *
42  * Stations are added per interface, but a special case exists with VLAN
43  * interfaces. When a station is bound to an AP interface, it may be moved
44  * into a VLAN identified by a VLAN interface index (%NL80211_ATTR_STA_VLAN).
45  * The station is still assumed to belong to the AP interface it was added
46  * to.
47  *
48  * Station handling varies per interface type and depending on the driver's
49  * capabilities.
50  *
51  * For drivers supporting TDLS with external setup (WIPHY_FLAG_SUPPORTS_TDLS
52  * and WIPHY_FLAG_TDLS_EXTERNAL_SETUP), the station lifetime is as follows:
53  *  - a setup station entry is added, not yet authorized, without any rate
54  *    or capability information, this just exists to avoid race conditions
55  *  - when the TDLS setup is done, a single NL80211_CMD_SET_STATION is valid
56  *    to add rate and capability information to the station and at the same
57  *    time mark it authorized.
58  *  - %NL80211_TDLS_ENABLE_LINK is then used
59  *  - after this, the only valid operation is to remove it by tearing down
60  *    the TDLS link (%NL80211_TDLS_DISABLE_LINK)
61  *

65 /**
66  * DOC: Frame transmission/registration support
67  *
68  * Frame transmission and registration support exists to allow userspace
69  * management entities such as wpa_supplicant react to management frames
70  * that are not being handled by the kernel. This includes, for example,
71  * certain classes of action frames that cannot be handled in the kernel
72  * for various reasons.
73  *
74  * Frame registration is done on a per-interface basis and registrations
75  * cannot be removed other than by closing the socket. It is possible to
76  * specify a registration filter to register, for example, only for a
77  * certain type of action frame. In particular with action frames, those
78  * that userspace registers for will not be returned as unhandled by the
79  * driver, so that the registered application has to take responsibility
80  * for doing that.
81  *
82  * The type of frame that can be registered for is also dependent on the
83  * driver and interface type. The frame types are advertised in wiphy
84  * attributes so applications know what to expect.
85  *
86  * NOTE: When an interface changes type while registrations are active,
87  *       these registrations are ignored until the interface type is
88  *       changed again. This means that changing the interface type can
89  *       lead to a situation that couldn't otherwise be produced, but
90  *       any such registrations will be dormant in the sense that they
91  *       will not be serviced, i.e. they will not receive any frames.
92  *
93  * Frame transmission allows userspace to send for example the required
94  * responses to action frames. It is subject to some sanity checking,
95  * but many frames can be transmitted. When a frame was transmitted, its
96  * status is indicated to the sending socket.
97  *
98  * For more technical details, see the corresponding command descriptions
99  * below.

102 /**
103  * DOC: Virtual interface / concurrency capabilities
104  *
105  * Some devices are able to operate with virtual MACs, they can have
106  * more than one virtual interface. The capability handling for this
107  * is a bit complex though, as there may be a number of restrictions
108  * on the types of concurrency that are supported.
109  *
110  * To start with, each device supports the interface types listed in
111  * the %NL80211_ATTR_SUPPORTED_IFTYPES attribute, but by listing the
112  * types there no concurrency is implied.
113  *
114  * Once concurrency is desired, more attributes must be observed:
115  * To start with, since some interface types are purely managed in
116  * software, like the AP-VLAN type in mac80211 for example, there's
117  * an additional list of these, they can be added at any time and
118  * are only restricted by some semantic restrictions (e.g. AP-VLAN
119  * cannot be added without a corresponding AP interface). This list
120  * is exported in the %NL80211_ATTR_SOFTWARE_IFTYPES attribute.
121  *
122  * Further, the list of supported combinations is exported. This is
123  * in the %NL80211_ATTR_INTERFACE_COMBINATIONS attribute. Basically,
124  * it exports a list of "groups", and at any point in time the
125  * interfaces that are currently active must fall into any one of
126  * the advertised groups. Within each group, there are restrictions
127  * on the number of interfaces of different types that are supported
128  * and also the number of different channels, along with potentially
129  * some other restrictions. See &enum nl80211_if_combination_attrs.
130  *
131  * All together, these attributes define the concurrency of virtual
132  * interfaces that a given device supports.

135 /**
136  * DOC: packet coalesce support
137  *
138  * In most cases, host that receives IPv4 and IPv6 multicast/broadcast
139  * packets does not do anything with these packets. Therefore the
140  * reception of these unwanted packets causes unnecessary processing
141  * and power consumption.
142  *
143  * Packet coalesce feature helps to reduce number of received interrupts
144  * to host by buffering these packets in firmware/hardware for some
145  * predefined time. Received interrupt will be generated when one of the
146  * following events occur.
147  * a) Expiration of hardware timer whose expiration time is set to maximum
148  * coalescing delay of matching coalesce rule.
149  * b) Coalescing buffer in hardware reaches it's limit.
150  * c) Packet doesn't match any of the configured coalesce rules.
151  *
152  * User needs to configure following parameters for creating a coalesce
153  * rule.
154  * a) Maximum coalescing delay
155  * b) List of packet patterns which needs to be matched
156  * c) Condition for coalescence. pattern 'match' or 'no match'
157  * Multiple such rules can be created.

262  *	regulatory domain. If %NL80211_ATTR_WIPHY is specified and the device
263  *	has a private regulatory domain, it will be returned. Otherwise, the
264  *	global regdomain will be returned.
265  *	A device will have a private regulatory domain if it uses the
266  *	regulatory_hint() API. Even when a private regdomain is used the channel
267  *	information will still be mended according to further hints from

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

1407  *	that match any of the sets will be reported.  These are
1408  *	pass-thru filter rules.
1409  *	For a match to succeed, the BSS must match all attributes of a
1410  *	set.  Since not every hardware supports matching all types of
1411  *	attributes, there is no guarantee that the reported BSSs are
1412  *	fully complying with the match sets and userspace needs to be
1413  *	able to ignore them by itself.
1414  *	Thus, the implementation is somewhat hardware-dependent, but
1415  *	this is only an optimization and the userspace application
1416  *	needs to handle all the non-filtered results anyway.
1417  *	If the match attributes don't make sense when combined with
1418  *	the values passed in @NL80211_ATTR_SCAN_SSIDS (eg. if an SSID
1419  *	is included in the probe request, but the match attributes

1489  *
1490  * @NL80211_ATTR_DONT_WAIT_FOR_ACK: Used with %NL80211_CMD_FRAME, this tells
1491  *	the driver to not wait for an acknowledgement. Note that due to this,
1492  *	it will also not give a status callback nor return a cookie. This is

3806  * DOC: TCP connection wakeup
3807  *
3808  * Some devices can establish a TCP connection in order to be woken up by a
3809  * packet coming in from outside their network segment, or behind NAT. If
3810  * configured, the device will establish a TCP connection to the given
3811  * service, and periodically send data to that service. The first data
3812  * packet is usually transmitted after SYN/ACK, also ACKing the SYN/ACK.
3813  * The data packets can optionally include a (little endian) sequence
3814  * number (in the TCP payload!) that is generated by the device, and, also
3815  * optionally, a token from a list of tokens. This serves as a keep-alive
3816  * with the service, and for NATed connections, etc.
3817  *
3818  * During this keep-alive period, the server doesn't send any data to the
3819  * client. When receiving data, it is compared against the wakeup pattern
3820  * (and mask) and if it matches, the host is woken up. Similarly, if the
3821  * connection breaks or cannot be established to start with, the host is
3822  * also woken up.
3823  *
3824  * Developer's note: ARP offload is required for this, otherwise TCP
3825  * response packets might not go through correctly.

4245  *	interface. An active monitor interface behaves like a normal monitor
4246  *	interface, but gets added to the driver. It ensures that incoming
4247  *	unicast packets directed at the configured interface address get ACKed.
4248  * @NL80211_FEATURE_AP_MODE_CHAN_WIDTH_CHANGE: This driver supports dynamic
4249  *	channel bandwidth change (e.g., HT 20 <-> 40 MHz channel) during the

4263  *	to enable dynack.
4264  * @NL80211_FEATURE_STATIC_SMPS: Device supports static spatial
4265  *	multiplexing powersave, ie. can turn off all but one chain
4266  *	even on HT connections that should be using more chains.
4267  * @NL80211_FEATURE_DYNAMIC_SMPS: Device supports dynamic spatial
4268  *	multiplexing powersave, ie. can turn off all but one chain
