42 /**
43  * DOC: Frame transmission/registration support
44  *
45  * Frame transmission and registration support exists to allow userspace
46  * management entities such as wpa_supplicant react to management frames
47  * that are not being handled by the kernel. This includes, for example,
48  * certain classes of action frames that cannot be handled in the kernel
49  * for various reasons.
50  *
51  * Frame registration is done on a per-interface basis and registrations
52  * cannot be removed other than by closing the socket. It is possible to
53  * specify a registration filter to register, for example, only for a
54  * certain type of action frame. In particular with action frames, those
55  * that userspace registers for will not be returned as unhandled by the
56  * driver, so that the registered application has to take responsibility
57  * for doing that.
58  *
59  * The type of frame that can be registered for is also dependent on the
60  * driver and interface type. The frame types are advertised in wiphy
61  * attributes so applications know what to expect.
62  *
63  * NOTE: When an interface changes type while registrations are active,
64  *       these registrations are ignored until the interface type is
65  *       changed again. This means that changing the interface type can
66  *       lead to a situation that couldn't otherwise be produced, but
67  *       any such registrations will be dormant in the sense that they
68  *       will not be serviced, i.e. they will not receive any frames.
69  *
70  * Frame transmission allows userspace to send for example the required
71  * responses to action frames. It is subject to some sanity checking,
72  * but many frames can be transmitted. When a frame was transmitted, its
73  * status is indicated to the sending socket.
74  *
75  * For more technical details, see the corresponding command descriptions
76  * below.

80  * DOC: Virtual interface / concurrency capabilities
81  *
82  * Some devices are able to operate with virtual MACs, they can have
83  * more than one virtual interface. The capability handling for this
84  * is a bit complex though, as there may be a number of restrictions
85  * on the types of concurrency that are supported.
86  *
87  * To start with, each device supports the interface types listed in
88  * the %NL80211_ATTR_SUPPORTED_IFTYPES attribute, but by listing the
89  * types there no concurrency is implied.
90  *
91  * Once concurrency is desired, more attributes must be observed:
92  * To start with, since some interface types are purely managed in
93  * software, like the AP-VLAN type in mac80211 for example, there's
94  * an additional list of these, they can be added at any time and
95  * are only restricted by some semantic restrictions (e.g. AP-VLAN
96  * cannot be added without a corresponding AP interface). This list
97  * is exported in the %NL80211_ATTR_SOFTWARE_IFTYPES attribute.
98  *
99  * Further, the list of supported combinations is exported. This is
100  * in the %NL80211_ATTR_INTERFACE_COMBINATIONS attribute. Basically,
101  * it exports a list of "groups", and at any point in time the
102  * interfaces that are currently active must fall into any one of
103  * the advertised groups. Within each group, there are restrictions
104  * on the number of interfaces of different types that are supported
105  * and also the number of different channels, along with potentially
106  * some other restrictions. See &enum nl80211_if_combination_attrs.
107  *
108  * All together, these attributes define the concurrency of virtual
109  * interfaces that a given device supports.

208  * @NL80211_CMD_GET_REG: ask the wireless core to send us its currently set
209  * 	regulatory domain.
210  * @NL80211_CMD_SET_REG: Set current regulatory domain. CRDA sends this command
211  *	after being queried by the kernel. CRDA replies by sending a regulatory
212  *	domain structure which consists of %NL80211_ATTR_REG_ALPHA set to our
213  *	current alpha2 if it found a match. It also provides
214  * 	NL80211_ATTR_REG_RULE_FLAGS, and a set of regulatory rules. Each
215  * 	regulatory rule is a nested set of attributes  given by
216  * 	%NL80211_ATTR_REG_RULE_FREQ_[START|END] and
217  * 	%NL80211_ATTR_FREQ_RANGE_MAX_BW with an attached power rule given by

219  * 	%NL80211_ATTR_REG_RULE_POWER_MAX_EIRP.
220  * @NL80211_CMD_REQ_SET_REG: ask the wireless core to set the regulatory domain
221  * 	to the specified ISO/IEC 3166-1 alpha2 country code. The core will
222  * 	store this as a valid request and then query userspace for it.
223  *
224  * @NL80211_CMD_GET_MESH_CONFIG: Get mesh networking properties for the
225  *	interface identified by %NL80211_ATTR_IFINDEX
226  *
227  * @NL80211_CMD_SET_MESH_CONFIG: Set mesh networking properties for the
228  *      interface identified by %NL80211_ATTR_IFINDEX
229  *
230  * @NL80211_CMD_SET_MGMT_EXTRA_IE: Set extra IEs for management frames. The
231  *	interface is identified with %NL80211_ATTR_IFINDEX and the management
232  *	frame subtype with %NL80211_ATTR_MGMT_SUBTYPE. The extra IE data to be
233  *	added to the end of the specified management frame is specified with
234  *	%NL80211_ATTR_IE. If the command succeeds, the requested data will be
235  *	added to all specified management frames generated by
236  *	kernel/firmware/driver.
237  *	Note: This command has been removed and it is only reserved at this
238  *	point to avoid re-using existing command number. The functionality this
239  *	command was planned for has been provided with cleaner design with the
240  *	option to specify additional IEs in NL80211_CMD_TRIGGER_SCAN,
241  *	NL80211_CMD_AUTHENTICATE, NL80211_CMD_ASSOCIATE,
242  *	NL80211_CMD_DEAUTHENTICATE, and NL80211_CMD_DISASSOCIATE.
243  *
244  * @NL80211_CMD_GET_SCAN: get scan results
245  * @NL80211_CMD_TRIGGER_SCAN: trigger a new scan with the given parameters
246  *	%NL80211_ATTR_TX_NO_CCK_RATE is used to decide whether to send the
247  *	probe requests at CCK rate or not.
248  * @NL80211_CMD_NEW_SCAN_RESULTS: scan notification (as a reply to
249  *	NL80211_CMD_GET_SCAN and on the "scan" multicast group)
250  * @NL80211_CMD_SCAN_ABORTED: scan was aborted, for unspecified reasons,
251  *	partial scan results may be available
252  *
253  * @NL80211_CMD_START_SCHED_SCAN: start a scheduled scan at certain
254  *	intervals, as specified by %NL80211_ATTR_SCHED_SCAN_INTERVAL.
255  *	Like with normal scans, if SSIDs (%NL80211_ATTR_SCAN_SSIDS)
256  *	are passed, they are used in the probe requests.  For
257  *	broadcast, a broadcast SSID must be passed (ie. an empty
258  *	string).  If no SSID is passed, no probe requests are sent and
259  *	a passive scan is performed.  %NL80211_ATTR_SCAN_FREQUENCIES,
260  *	if passed, define which channels should be scanned; if not
261  *	passed, all channels allowed for the current regulatory domain
262  *	are used.  Extra IEs can also be passed from the userspace by
263  *	using the %NL80211_ATTR_IE attribute.
264  * @NL80211_CMD_STOP_SCHED_SCAN: stop a scheduled scan.  Returns -ENOENT
265  *	if scheduled scan is not running.
266  * @NL80211_CMD_SCHED_SCAN_RESULTS: indicates that there are scheduled scan
267  *	results available.
268  * @NL80211_CMD_SCHED_SCAN_STOPPED: indicates that the scheduled scan has
269  *	stopped.  The driver may issue this event at any time during a
270  *	scheduled scan.  One reason for stopping the scan is if the hardware
271  *	does not support starting an association or a normal scan while running
272  *	a scheduled scan.  This event is also sent when the
273  *	%NL80211_CMD_STOP_SCHED_SCAN command is received or when the interface
274  *	is brought down while a scheduled scan was running.
275  *
276  * @NL80211_CMD_GET_SURVEY: get survey resuls, e.g. channel occupation
277  *      or noise level
278  * @NL80211_CMD_NEW_SURVEY_RESULTS: survey data notification (as a reply to
279  *	NL80211_CMD_GET_SURVEY and on the "scan" multicast group)
280  *
281  * @NL80211_CMD_SET_PMKSA: Add a PMKSA cache entry, using %NL80211_ATTR_MAC
282  *	(for the BSSID) and %NL80211_ATTR_PMKID.
283  * @NL80211_CMD_DEL_PMKSA: Delete a PMKSA cache entry, using %NL80211_ATTR_MAC
284  *	(for the BSSID) and %NL80211_ATTR_PMKID.
285  * @NL80211_CMD_FLUSH_PMKSA: Flush all PMKSA cache entries.
286  *
287  * @NL80211_CMD_REG_CHANGE: indicates to userspace the regulatory domain
288  * 	has been changed and provides details of the request information
289  * 	that caused the change such as who initiated the regulatory request
290  * 	(%NL80211_ATTR_REG_INITIATOR), the wiphy_idx
291  * 	(%NL80211_ATTR_REG_ALPHA2) on which the request was made from if
292  * 	the initiator was %NL80211_REGDOM_SET_BY_COUNTRY_IE or
293  * 	%NL80211_REGDOM_SET_BY_DRIVER, the type of regulatory domain
294  * 	set (%NL80211_ATTR_REG_TYPE), if the type of regulatory domain is
295  * 	%NL80211_REG_TYPE_COUNTRY the alpha2 to which we have moved on
296  * 	to (%NL80211_ATTR_REG_ALPHA2).
297  * @NL80211_CMD_REG_BEACON_HINT: indicates to userspace that an AP beacon
298  * 	has been found while world roaming thus enabling active scan or
299  * 	any mode of operation that initiates TX (beacons) on a channel
300  * 	where we would not have been able to do either before. As an example
301  * 	if you are world roaming (regulatory domain set to world or if your
302  * 	driver is using a custom world roaming regulatory domain) and while
303  * 	doing a passive scan on the 5 GHz band you find an AP there (if not
304  * 	on a DFS channel) you will now be able to actively scan for that AP
305  * 	or use AP mode on your card on that same channel. Note that this will
306  * 	never be used for channels 1-11 on the 2 GHz band as they are always
307  * 	enabled world wide. This beacon hint is only sent if your device had
308  * 	either disabled active scanning or beaconing on a channel. We send to
309  * 	userspace the wiphy on which we removed a restriction from
310  * 	(%NL80211_ATTR_WIPHY) and the channel on which this occurred
311  * 	before (%NL80211_ATTR_FREQ_BEFORE) and after (%NL80211_ATTR_FREQ_AFTER)
312  * 	the beacon hint was processed.
313  *
314  * @NL80211_CMD_AUTHENTICATE: authentication request and notification.
315  *	This command is used both as a command (request to authenticate) and
316  *	as an event on the "mlme" multicast group indicating completion of the
317  *	authentication process.
318  *	When used as a command, %NL80211_ATTR_IFINDEX is used to identify the
319  *	interface. %NL80211_ATTR_MAC is used to specify PeerSTAAddress (and
320  *	BSSID in case of station mode). %NL80211_ATTR_SSID is used to specify
321  *	the SSID (mainly for association, but is included in authentication
322  *	request, too, to help BSS selection. %NL80211_ATTR_WIPHY_FREQ is used
323  *	to specify the frequence of the channel in MHz. %NL80211_ATTR_AUTH_TYPE
324  *	is used to specify the authentication type. %NL80211_ATTR_IE is used to
325  *	define IEs (VendorSpecificInfo, but also including RSN IE and FT IEs)
326  *	to be added to the frame.
327  *	When used as an event, this reports reception of an Authentication
328  *	frame in station and IBSS modes when the local MLME processed the
329  *	frame, i.e., it was for the local STA and was received in correct
330  *	state. This is similar to MLME-AUTHENTICATE.confirm primitive in the
331  *	MLME SAP interface (kernel providing MLME, userspace SME). The
332  *	included %NL80211_ATTR_FRAME attribute contains the management frame
333  *	(including both the header and frame body, but not FCS). This event is
334  *	also used to indicate if the authentication attempt timed out. In that
335  *	case the %NL80211_ATTR_FRAME attribute is replaced with a
336  *	%NL80211_ATTR_TIMED_OUT flag (and %NL80211_ATTR_MAC to indicate which
337  *	pending authentication timed out).
338  * @NL80211_CMD_ASSOCIATE: association request and notification; like
339  *	NL80211_CMD_AUTHENTICATE but for Association and Reassociation
340  *	(similar to MLME-ASSOCIATE.request, MLME-REASSOCIATE.request,
341  *	MLME-ASSOCIATE.confirm or MLME-REASSOCIATE.confirm primitives).
342  * @NL80211_CMD_DEAUTHENTICATE: deauthentication request and notification; like
343  *	NL80211_CMD_AUTHENTICATE but for Deauthentication frames (similar to
344  *	MLME-DEAUTHENTICATION.request and MLME-DEAUTHENTICATE.indication
345  *	primitives).
346  * @NL80211_CMD_DISASSOCIATE: disassociation request and notification; like
347  *	NL80211_CMD_AUTHENTICATE but for Disassociation frames (similar to
348  *	MLME-DISASSOCIATE.request and MLME-DISASSOCIATE.indication primitives).
349  *
350  * @NL80211_CMD_MICHAEL_MIC_FAILURE: notification of a locally detected Michael
351  *	MIC (part of TKIP) failure; sent on the "mlme" multicast group; the
352  *	event includes %NL80211_ATTR_MAC to describe the source MAC address of
353  *	the frame with invalid MIC, %NL80211_ATTR_KEY_TYPE to show the key
354  *	type, %NL80211_ATTR_KEY_IDX to indicate the key identifier, and
355  *	%NL80211_ATTR_KEY_SEQ to indicate the TSC value of the frame; this
356  *	event matches with MLME-MICHAELMICFAILURE.indication() primitive
357  *
358  * @NL80211_CMD_JOIN_IBSS: Join a new IBSS -- given at least an SSID and a
359  *	FREQ attribute (for the initial frequency if no peer can be found)
360  *	and optionally a MAC (as BSSID) and FREQ_FIXED attribute if those
361  *	should be fixed rather than automatically determined. Can only be
362  *	executed on a network interface that is UP, and fixed BSSID/FREQ
363  *	may be rejected. Another optional parameter is the beacon interval,
364  *	given in the %NL80211_ATTR_BEACON_INTERVAL attribute, which if not
365  *	given defaults to 100 TU (102.4ms).
366  * @NL80211_CMD_LEAVE_IBSS: Leave the IBSS -- no special arguments, the IBSS is
367  *	determined by the network interface.
368  *
369  * @NL80211_CMD_TESTMODE: testmode command, takes a wiphy (or ifindex) attribute
370  *	to identify the device, and the TESTDATA blob attribute to pass through
371  *	to the driver.
372  *
373  * @NL80211_CMD_CONNECT: connection request and notification; this command
374  *	requests to connect to a specified network but without separating
375  *	auth and assoc steps. For this, you need to specify the SSID in a
376  *	%NL80211_ATTR_SSID attribute, and can optionally specify the association
377  *	IEs in %NL80211_ATTR_IE, %NL80211_ATTR_AUTH_TYPE, %NL80211_ATTR_MAC,
378  *	%NL80211_ATTR_WIPHY_FREQ, %NL80211_ATTR_CONTROL_PORT,

381  *	Background scan period can optionally be
382  *	specified in %NL80211_ATTR_BG_SCAN_PERIOD,
383  *	if not specified default background scan configuration
384  *	in driver is used and if period value is 0, bg scan will be disabled.
385  *	This attribute is ignored if driver does not support roam scan.
386  *	It is also sent as an event, with the BSSID and response IEs when the
387  *	connection is established or failed to be established. This can be
388  *	determined by the STATUS_CODE attribute.
389  * @NL80211_CMD_ROAM: request that the card roam (currently not implemented),
390  *	sent as an event when the card/driver roamed by itself.
391  * @NL80211_CMD_DISCONNECT: drop a given connection; also used to notify
392  *	userspace that a connection was dropped by the AP or due to other
393  *	reasons, for this the %NL80211_ATTR_DISCONNECTED_BY_AP and
394  *	%NL80211_ATTR_REASON_CODE attributes are used.
395  *
396  * @NL80211_CMD_SET_WIPHY_NETNS: Set a wiphy's netns. Note that all devices
397  *	associated with this wiphy must be down and will follow.
398  *
399  * @NL80211_CMD_REMAIN_ON_CHANNEL: Request to remain awake on the specified
400  *	channel for the specified amount of time. This can be used to do
401  *	off-channel operations like transmit a Public Action frame and wait for
402  *	a response while being associated to an AP on another channel.
403  *	%NL80211_ATTR_IFINDEX is used to specify which interface (and thus
404  *	radio) is used. %NL80211_ATTR_WIPHY_FREQ is used to specify the
405  *	frequency for the operation.
406  *	%NL80211_ATTR_DURATION is used to specify the duration in milliseconds
407  *	to remain on the channel. This command is also used as an event to
408  *	notify when the requested duration starts (it may take a while for the
409  *	driver to schedule this time due to other concurrent needs for the
410  *	radio).
411  *	When called, this operation returns a cookie (%NL80211_ATTR_COOKIE)
412  *	that will be included with any events pertaining to this request;
413  *	the cookie is also used to cancel the request.
414  * @NL80211_CMD_CANCEL_REMAIN_ON_CHANNEL: This command can be used to cancel a
415  *	pending remain-on-channel duration if the desired operation has been
416  *	completed prior to expiration of the originally requested duration.
417  *	%NL80211_ATTR_WIPHY or %NL80211_ATTR_IFINDEX is used to specify the
418  *	radio. The %NL80211_ATTR_COOKIE attribute must be given as well to
419  *	uniquely identify the request.
420  *	This command is also used as an event to notify when a requested
421  *	remain-on-channel duration has expired.
422  *
423  * @NL80211_CMD_SET_TX_BITRATE_MASK: Set the mask of rates to be used in TX
424  *	rate selection. %NL80211_ATTR_IFINDEX is used to specify the interface
425  *	and @NL80211_ATTR_TX_RATES the set of allowed rates.
426  *
427  * @NL80211_CMD_REGISTER_FRAME: Register for receiving certain mgmt frames
428  *	(via @NL80211_CMD_FRAME) for processing in userspace. This command
429  *	requires an interface index, a frame type attribute (optional for
430  *	backward compatibility reasons, if not given assumes action frames)
431  *	and a match attribute containing the first few bytes of the frame
432  *	that should match, e.g. a single byte for only a category match or
433  *	four bytes for vendor frames including the OUI. The registration
434  *	cannot be dropped, but is removed automatically when the netlink
435  *	socket is closed. Multiple registrations can be made.
436  * @NL80211_CMD_REGISTER_ACTION: Alias for @NL80211_CMD_REGISTER_FRAME for
437  *	backward compatibility
438  * @NL80211_CMD_FRAME: Management frame TX request and RX notification. This
439  *	command is used both as a request to transmit a management frame and
440  *	as an event indicating reception of a frame that was not processed in
441  *	kernel code, but is for us (i.e., which may need to be processed in a
442  *	user space application). %NL80211_ATTR_FRAME is used to specify the
443  *	frame contents (including header). %NL80211_ATTR_WIPHY_FREQ is used
444  *	to indicate on which channel the frame is to be transmitted or was
445  *	received. If this channel is not the current channel (remain-on-channel
446  *	or the operational channel) the device will switch to the given channel
447  *	and transmit the frame, optionally waiting for a response for the time
448  *	specified using %NL80211_ATTR_DURATION. When called, this operation
449  *	returns a cookie (%NL80211_ATTR_COOKIE) that will be included with the
450  *	TX status event pertaining to the TX request.
451  *	%NL80211_ATTR_TX_NO_CCK_RATE is used to decide whether to send the
452  *	management frames at CCK rate or not in 2GHz band.
453  * @NL80211_CMD_FRAME_WAIT_CANCEL: When an off-channel TX was requested, this
454  *	command may be used with the corresponding cookie to cancel the wait
455  *	time if it is known that it is no longer necessary.
456  * @NL80211_CMD_ACTION: Alias for @NL80211_CMD_FRAME for backward compatibility.
457  * @NL80211_CMD_FRAME_TX_STATUS: Report TX status of a management frame
458  *	transmitted with %NL80211_CMD_FRAME. %NL80211_ATTR_COOKIE identifies
459  *	the TX command and %NL80211_ATTR_FRAME includes the contents of the
460  *	frame. %NL80211_ATTR_ACK flag is included if the recipient acknowledged
461  *	the frame.
462  * @NL80211_CMD_ACTION_TX_STATUS: Alias for @NL80211_CMD_FRAME_TX_STATUS for
463  *	backward compatibility.
464  *
465  * @NL80211_CMD_SET_POWER_SAVE: Set powersave, using %NL80211_ATTR_PS_STATE
466  * @NL80211_CMD_GET_POWER_SAVE: Get powersave status in %NL80211_ATTR_PS_STATE
467  *
468  * @NL80211_CMD_SET_CQM: Connection quality monitor configuration. This command
469  *	is used to configure connection quality monitoring notification trigger
470  *	levels.
471  * @NL80211_CMD_NOTIFY_CQM: Connection quality monitor notification. This
472  *	command is used as an event to indicate the that a trigger level was
473  *	reached.
474  * @NL80211_CMD_SET_CHANNEL: Set the channel (using %NL80211_ATTR_WIPHY_FREQ
475  *	and the attributes determining channel width) the given interface
476  *	(identifed by %NL80211_ATTR_IFINDEX) shall operate on.
477  *	In case multiple channels are supported by the device, the mechanism
478  *	with which it switches channels is implementation-defined.
479  *	When a monitor interface is given, it can only switch channel while
480  *	no other interfaces are operating to avoid disturbing the operation
481  *	of any other interfaces, and other interfaces will again take
482  *	precedence when they are used.
483  *
484  * @NL80211_CMD_SET_WDS_PEER: Set the MAC address of the peer on a WDS interface.
485  *
486  * @NL80211_CMD_JOIN_MESH: Join a mesh. The mesh ID must be given, and initial
487  *	mesh config parameters may be given.
488  * @NL80211_CMD_LEAVE_MESH: Leave the mesh network -- no special arguments, the
489  *	network is determined by the network interface.
490  *
491  * @NL80211_CMD_UNPROT_DEAUTHENTICATE: Unprotected deauthentication frame
492  *	notification. This event is used to indicate that an unprotected
493  *	deauthentication frame was dropped when MFP is in use.
494  * @NL80211_CMD_UNPROT_DISASSOCIATE: Unprotected disassociation frame
495  *	notification. This event is used to indicate that an unprotected
496  *	disassociation frame was dropped when MFP is in use.
497  *
498  * @NL80211_CMD_NEW_PEER_CANDIDATE: Notification on the reception of a
499  *      beacon or probe response from a compatible mesh peer.  This is only
500  *      sent while no station information (sta_info) exists for the new peer
501  *      candidate and when @NL80211_MESH_SETUP_USERSPACE_AUTH is set.  On
502  *      reception of this notification, userspace may decide to create a new
503  *      station (@NL80211_CMD_NEW_STATION).  To stop this notification from
504  *      reoccurring, the userspace authentication daemon may want to create the
505  *      new station with the AUTHENTICATED flag unset and maybe change it later
506  *      depending on the authentication result.
507  *
508  * @NL80211_CMD_GET_WOWLAN: get Wake-on-Wireless-LAN (WoWLAN) settings.
509  * @NL80211_CMD_SET_WOWLAN: set Wake-on-Wireless-LAN (WoWLAN) settings.
510  *	Since wireless is more complex than wired ethernet, it supports
511  *	various triggers. These triggers can be configured through this
512  *	command with the %NL80211_ATTR_WOWLAN_TRIGGERS attribute. For
513  *	more background information, see
514  *	http://wireless.kernel.org/en/users/Documentation/WoWLAN.
515  *
516  * @NL80211_CMD_SET_REKEY_OFFLOAD: This command is used give the driver
517  *	the necessary information for supporting GTK rekey offload. This
518  *	feature is typically used during WoWLAN. The configuration data
519  *	is contained in %NL80211_ATTR_REKEY_DATA (which is nested and
520  *	contains the data in sub-attributes). After rekeying happened,
521  *	this command may also be sent by the driver as an MLME event to
522  *	inform userspace of the new replay counter.
523  *
524  * @NL80211_CMD_PMKSA_CANDIDATE: This is used as an event to inform userspace
525  *	of PMKSA caching dandidates.
526  *
527  * @NL80211_CMD_TDLS_OPER: Perform a high-level TDLS command (e.g. link setup).
528  *	In addition, this can be used as an event to request userspace to take
529  *	actions on TDLS links (set up a new link or tear down an existing one).
530  *	In such events, %NL80211_ATTR_TDLS_OPERATION indicates the requested
531  *	operation, %NL80211_ATTR_MAC contains the peer MAC address, and
532  *	%NL80211_ATTR_REASON_CODE the reason code to be used (only with
533  *	%NL80211_TDLS_TEARDOWN).
534  * @NL80211_CMD_TDLS_MGMT: Send a TDLS management frame.
535  *
536  * @NL80211_CMD_UNEXPECTED_FRAME: Used by an application controlling an AP
537  *	(or GO) interface (i.e. hostapd) to ask for unexpected frames to
538  *	implement sending deauth to stations that send unexpected class 3
539  *	frames. Also used as the event sent by the kernel when such a frame
540  *	is received.
541  *	For the event, the %NL80211_ATTR_MAC attribute carries the TA and
542  *	other attributes like the interface index are present.
543  *	If used as the command it must have an interface index and you can
544  *	only unsubscribe from the event by closing the socket. Subscription
545  *	is also for %NL80211_CMD_UNEXPECTED_4ADDR_FRAME events.
546  *
547  * @NL80211_CMD_UNEXPECTED_4ADDR_FRAME: Sent as an event indicating that the
548  *	associated station identified by %NL80211_ATTR_MAC sent a 4addr frame
549  *	and wasn't already in a 4-addr VLAN. The event will be sent similarly
550  *	to the %NL80211_CMD_UNEXPECTED_FRAME event, to the same listener.
551  *
552  * @NL80211_CMD_PROBE_CLIENT: Probe an associated station on an AP interface
553  *	by sending a null data frame to it and reporting when the frame is
554  *	acknowleged. This is used to allow timing out inactive clients. Uses
555  *	%NL80211_ATTR_IFINDEX and %NL80211_ATTR_MAC. The command returns a
556  *	direct reply with an %NL80211_ATTR_COOKIE that is later used to match
557  *	up the event with the request. The event includes the same data and
558  *	has %NL80211_ATTR_ACK set if the frame was ACKed.
559  *
560  * @NL80211_CMD_REGISTER_BEACONS: Register this socket to receive beacons from
561  *	other BSSes when any interfaces are in AP mode. This helps implement
562  *	OLBC handling in hostapd. Beacons are reported in %NL80211_CMD_FRAME
563  *	messages. Note that per PHY only one application may register.
564  *
565  * @NL80211_CMD_SET_NOACK_MAP: sets a bitmap for the individual TIDs whether
566  *      No Acknowledgement Policy should be applied.
567  *
568  * @NL80211_CMD_CH_SWITCH_NOTIFY: An AP or GO may decide to switch channels
569  *	independently of the userspace SME, send this event indicating
570  *	%NL80211_ATTR_IFINDEX is now on %NL80211_ATTR_WIPHY_FREQ and the
571  *	attributes determining channel width.
572  *
573  * @NL80211_CMD_START_P2P_DEVICE: Start the given P2P Device, identified by
574  *	its %NL80211_ATTR_WDEV identifier. It must have been created with
575  *	%NL80211_CMD_NEW_INTERFACE previously. After it has been started, the
576  *	P2P Device can be used for P2P operations, e.g. remain-on-channel and
577  *	public action frame TX.
578  * @NL80211_CMD_STOP_P2P_DEVICE: Stop the given P2P Device, identified by
579  *	its %NL80211_ATTR_WDEV identifier.
580  *
581  * @NL80211_CMD_CONN_FAILED: connection request to an AP failed; used to
582  *	notify userspace that AP has rejected the connection request from a
583  *	station, due to particular reason. %NL80211_ATTR_CONN_FAILED_REASON
584  *	is used for this.
585  *
586  * @NL80211_CMD_SET_MCAST_RATE: Change the rate used to send multicast frames
587  *	for IBSS or MESH vif.
588  *
589  * @NL80211_CMD_MAX: highest used command number
590  * @__NL80211_CMD_AFTER_LAST: internal use

1073  *
1074  * @NL80211_ATTR_LOCAL_STATE_CHANGE: Flag attribute to indicate that a command
1075  *	is requesting a local authentication/association state change without
1076  *	invoking actual management frame exchange. This can be used with
1077  *	NL80211_CMD_AUTHENTICATE, NL80211_CMD_DEAUTHENTICATE,
1078  *	NL80211_CMD_DISASSOCIATE.
1079  *

1096  *
1097  *	Each bit represents one antenna, starting with antenna 1 at the first
1098  *	bit. Depending on which antennas are selected in the bitmap, 802.11n
1099  *	drivers can derive which chainmasks to use (if all antennas belonging to
1100  *	a particular chain are disabled this chain should be disabled) and if
1101  *	a chain has diversity antennas wether diversity should be used or not.
1102  *	HT capabilities (STBC, TX Beamforming, Antenna selection) can be
1103  *	derived from the available chains after applying the antenna mask.
1104  *	Non-802.11n drivers can derive wether to use diversity or not.

1106  *	support by returning -EINVAL.
1107  *
1108  * @NL80211_ATTR_WIPHY_ANTENNA_RX: Bitmap of allowed antennas for receiving.
1109  *	This can be used to mask out antennas which are not attached or should

1123  *	transmitted on another channel when the channel given doesn't match
1124  *	the current channel. If the current channel doesn't match and this
1125  *	flag isn't set, the frame will be rejected. This is also used as an
1126  *	nl80211 capability flag.
1127  *
1128  * @NL80211_ATTR_BSS_HT_OPMODE: HT operation mode (u16)
1129  *
1130  * @NL80211_ATTR_KEY_DEFAULT_TYPES: A nested attribute containing flags

1135  *	changed once the mesh is active.
1136  * @NL80211_ATTR_MESH_CONFIG: Mesh configuration parameters, a nested attribute
1137  *	containing attributes from &enum nl80211_meshconf_params.
1138  * @NL80211_ATTR_SUPPORT_MESH_AUTH: Currently, this means the underlying driver
1139  *	allows auth frames in a mesh to be passed to userspace for processing via
1140  *	the @NL80211_MESH_SETUP_USERSPACE_AUTH flag.
1141  * @NL80211_ATTR_STA_PLINK_STATE: The state of a mesh peer link as
1142  *	defined in &enum nl80211_plink_state. Used when userspace is

1149  *	indicate which WoW triggers should be enabled. This is also
1150  *	used by %NL80211_CMD_GET_WOWLAN to get the currently enabled WoWLAN
1151  *	triggers.
1152  *
1153  * @NL80211_ATTR_SCHED_SCAN_INTERVAL: Interval between scheduled scan
1154  *	cycles, in msecs.
1155  *
1156  * @NL80211_ATTR_SCHED_SCAN_MATCH: Nested attribute with one or more
1157  *	sets of attributes to match during scheduled scans.  Only BSSs
1158  *	that match any of the sets will be reported.  These are
1159  *	pass-thru filter rules.
1160  *	For a match to succeed, the BSS must match all attributes of a
1161  *	set.  Since not every hardware supports matching all types of
1162  *	attributes, there is no guarantee that the reported BSSs are
1163  *	fully complying with the match sets and userspace needs to be
1164  *	able to ignore them by itself.
1165  *	Thus, the implementation is somewhat hardware-dependent, but
1166  *	this is only an optimization and the userspace application
1167  *	needs to handle all the non-filtered results anyway.
1168  *	If the match attributes don't make sense when combined with
1169  *	the values passed in @NL80211_ATTR_SCAN_SSIDS (eg. if an SSID
1170  *	is included in the probe request, but the match attributes
1171  *	will never let it go through), -EINVAL may be returned.

1181  *
1182  * @NL80211_ATTR_REKEY_DATA: nested attribute containing the information
1183  *	necessary for GTK rekeying in the device, see &enum nl80211_rekey_data.
1184  *
1185  * @NL80211_ATTR_SCAN_SUPP_RATES: rates per to be advertised as supported in scan,
1186  *	nested array attribute containing an entry for each band, with the entry
1187  *	being a list of supported rates as defined by IEEE 802.11 7.3.2.2 but

1196  *	provide extra IEs (e.g., WPS/P2P IE) into Probe Response frames when the
1197  *	driver (or firmware) replies to Probe Request frames.
1198  * @NL80211_ATTR_IE_ASSOC_RESP: Information element(s) for (Re)Association
1199  *	Response frames. This is used with %NL80211_CMD_NEW_BEACON and
1200  *	%NL80211_CMD_SET_BEACON to provide extra IEs (e.g., WPS/P2P IE) into
1201  *	(Re)Association Response frames when the driver (or firmware) replies to
1202  *	(Re)Association Request frames.
1203  *
1204  * @NL80211_ATTR_STA_WME: Nested attribute containing the wme configuration
1205  *	of the station, see &enum nl80211_sta_wme_attr.

1216  *	for management frames transmission. In order to avoid p2p probe/action
1217  *	frames are being transmitted at CCK rate in 2GHz band, the user space
1218  *	applications use this attribute.
1219  *	This attribute is used with %NL80211_CMD_TRIGGER_SCAN and
1220  *	%NL80211_CMD_FRAME commands.
1221  *
1222  * @NL80211_ATTR_TDLS_ACTION: Low level TDLS action code (e.g. link setup

1235  *
1236  * @NL80211_ATTR_DEVICE_AP_SME: This u32 attribute may be listed for devices
1237  *	that have AP support to indicate that they have the AP SME integrated
1238  *	with support for the features listed in this attribute, see
1239  *	&enum nl80211_ap_sme_features.
1240  *
1241  * @NL80211_ATTR_DONT_WAIT_FOR_ACK: Used with %NL80211_CMD_FRAME, this tells
1242  *	the driver to not wait for an acknowledgement. Note that due to this,
1243  *	it will also not give a status callback nor return a cookie. This is
1244  *	mostly useful for probe responses to save airtime.
1245  *
1246  * @NL80211_ATTR_FEATURE_FLAGS: This u32 attribute contains flags from
1247  *	&enum nl80211_feature_flags and is advertised in wiphy information.

1273  *      up to 16 TIDs.
1274  *
1275  * @NL80211_ATTR_INACTIVITY_TIMEOUT: timeout value in seconds, this can be
1276  *	used by the drivers which has MLME in firmware and does not have support
1277  *	to report per station tx/rx activity to free up the staion entry from
1278  *	the list. This needs to be used when the driver advertises the
1279  *	capability to timeout the stations.
1280  *
1281  * @NL80211_ATTR_RX_SIGNAL_DBM: signal strength in dBm (as a 32-bit int);
1282  *	this attribute is (depending on the driver capabilities) added to
