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.

206  * 	regulatory domain.
207  * @NL80211_CMD_SET_REG: Set current regulatory domain. CRDA sends this command

220  *
221  * @NL80211_CMD_GET_MESH_CONFIG: Get mesh networking properties for the

226  *
227  * @NL80211_CMD_SET_MGMT_EXTRA_IE: Set extra IEs for management frames. The
228  *	interface is identified with %NL80211_ATTR_IFINDEX and the management
229  *	frame subtype with %NL80211_ATTR_MGMT_SUBTYPE. The extra IE data to be
230  *	added to the end of the specified management frame is specified with
231  *	%NL80211_ATTR_IE. If the command succeeds, the requested data will be
232  *	added to all specified management frames generated by
233  *	kernel/firmware/driver.
234  *	Note: This command has been removed and it is only reserved at this
235  *	point to avoid re-using existing command number. The functionality this
236  *	command was planned for has been provided with cleaner design with the
237  *	option to specify additional IEs in NL80211_CMD_TRIGGER_SCAN,
238  *	NL80211_CMD_AUTHENTICATE, NL80211_CMD_ASSOCIATE,
239  *	NL80211_CMD_DEAUTHENTICATE, and NL80211_CMD_DISASSOCIATE.
240  *
241  * @NL80211_CMD_GET_SCAN: get scan results
242  * @NL80211_CMD_TRIGGER_SCAN: trigger a new scan with the given parameters
243  *	%NL80211_ATTR_TX_NO_CCK_RATE is used to decide whether to send the
244  *	probe requests at CCK rate or not.
245  * @NL80211_CMD_NEW_SCAN_RESULTS: scan notification (as a reply to
246  *	NL80211_CMD_GET_SCAN and on the "scan" multicast group)
247  * @NL80211_CMD_SCAN_ABORTED: scan was aborted, for unspecified reasons,
248  *	partial scan results may be available
249  *
250  * @NL80211_CMD_START_SCHED_SCAN: start a scheduled scan at certain
251  *	intervals, as specified by %NL80211_ATTR_SCHED_SCAN_INTERVAL.
252  *	Like with normal scans, if SSIDs (%NL80211_ATTR_SCAN_SSIDS)
253  *	are passed, they are used in the probe requests.  For
254  *	broadcast, a broadcast SSID must be passed (ie. an empty
255  *	string).  If no SSID is passed, no probe requests are sent and
256  *	a passive scan is performed.  %NL80211_ATTR_SCAN_FREQUENCIES,
257  *	if passed, define which channels should be scanned; if not
258  *	passed, all channels allowed for the current regulatory domain
259  *	are used.  Extra IEs can also be passed from the userspace by
260  *	using the %NL80211_ATTR_IE attribute.
261  * @NL80211_CMD_STOP_SCHED_SCAN: stop a scheduled scan.  Returns -ENOENT
262  *	if scheduled scan is not running.
263  * @NL80211_CMD_SCHED_SCAN_RESULTS: indicates that there are scheduled scan
264  *	results available.
265  * @NL80211_CMD_SCHED_SCAN_STOPPED: indicates that the scheduled scan has
266  *	stopped.  The driver may issue this event at any time during a
267  *	scheduled scan.  One reason for stopping the scan is if the hardware
268  *	does not support starting an association or a normal scan while running
269  *	a scheduled scan.  This event is also sent when the
270  *	%NL80211_CMD_STOP_SCHED_SCAN command is received or when the interface
271  *	is brought down while a scheduled scan was running.
272  *
273  * @NL80211_CMD_GET_SURVEY: get survey resuls, e.g. channel occupation
274  *      or noise level
275  * @NL80211_CMD_NEW_SURVEY_RESULTS: survey data notification (as a reply to
276  *	NL80211_CMD_GET_SURVEY and on the "scan" multicast group)
277  *
278  * @NL80211_CMD_REG_CHANGE: indicates to userspace the regulatory domain
279  * 	has been changed and provides details of the request information
280  * 	that caused the change such as who initiated the regulatory request
281  * 	(%NL80211_ATTR_REG_INITIATOR), the wiphy_idx
282  * 	(%NL80211_ATTR_REG_ALPHA2) on which the request was made from if
283  * 	the initiator was %NL80211_REGDOM_SET_BY_COUNTRY_IE or
284  * 	%NL80211_REGDOM_SET_BY_DRIVER, the type of regulatory domain
285  * 	set (%NL80211_ATTR_REG_TYPE), if the type of regulatory domain is
286  * 	%NL80211_REG_TYPE_COUNTRY the alpha2 to which we have moved on
287  * 	to (%NL80211_ATTR_REG_ALPHA2).
288  * @NL80211_CMD_REG_BEACON_HINT: indicates to userspace that an AP beacon
289  * 	has been found while world roaming thus enabling active scan or
290  * 	any mode of operation that initiates TX (beacons) on a channel
291  * 	where we would not have been able to do either before. As an example
292  * 	if you are world roaming (regulatory domain set to world or if your
293  * 	driver is using a custom world roaming regulatory domain) and while
294  * 	doing a passive scan on the 5 GHz band you find an AP there (if not
295  * 	on a DFS channel) you will now be able to actively scan for that AP
296  * 	or use AP mode on your card on that same channel. Note that this will
297  * 	never be used for channels 1-11 on the 2 GHz band as they are always
298  * 	enabled world wide. This beacon hint is only sent if your device had
299  * 	either disabled active scanning or beaconing on a channel. We send to
300  * 	userspace the wiphy on which we removed a restriction from
301  * 	(%NL80211_ATTR_WIPHY) and the channel on which this occurred
302  * 	before (%NL80211_ATTR_FREQ_BEFORE) and after (%NL80211_ATTR_FREQ_AFTER)
303  * 	the beacon hint was processed.
304  *
305  * @NL80211_CMD_AUTHENTICATE: authentication request and notification.
306  *	This command is used both as a command (request to authenticate) and
307  *	as an event on the "mlme" multicast group indicating completion of the
308  *	authentication process.
309  *	When used as a command, %NL80211_ATTR_IFINDEX is used to identify the
310  *	interface. %NL80211_ATTR_MAC is used to specify PeerSTAAddress (and
311  *	BSSID in case of station mode). %NL80211_ATTR_SSID is used to specify
312  *	the SSID (mainly for association, but is included in authentication
313  *	request, too, to help BSS selection. %NL80211_ATTR_WIPHY_FREQ is used
314  *	to specify the frequence of the channel in MHz. %NL80211_ATTR_AUTH_TYPE
315  *	is used to specify the authentication type. %NL80211_ATTR_IE is used to
316  *	define IEs (VendorSpecificInfo, but also including RSN IE and FT IEs)
317  *	to be added to the frame.
318  *	When used as an event, this reports reception of an Authentication
319  *	frame in station and IBSS modes when the local MLME processed the
320  *	frame, i.e., it was for the local STA and was received in correct
321  *	state. This is similar to MLME-AUTHENTICATE.confirm primitive in the
322  *	MLME SAP interface (kernel providing MLME, userspace SME). The
323  *	included %NL80211_ATTR_FRAME attribute contains the management frame
324  *	(including both the header and frame body, but not FCS). This event is
325  *	also used to indicate if the authentication attempt timed out. In that
326  *	case the %NL80211_ATTR_FRAME attribute is replaced with a
327  *	%NL80211_ATTR_TIMED_OUT flag (and %NL80211_ATTR_MAC to indicate which
328  *	pending authentication timed out).
329  * @NL80211_CMD_ASSOCIATE: association request and notification; like
330  *	NL80211_CMD_AUTHENTICATE but for Association and Reassociation
331  *	(similar to MLME-ASSOCIATE.request, MLME-REASSOCIATE.request,
332  *	MLME-ASSOCIATE.confirm or MLME-REASSOCIATE.confirm primitives).
333  * @NL80211_CMD_DEAUTHENTICATE: deauthentication request and notification; like
334  *	NL80211_CMD_AUTHENTICATE but for Deauthentication frames (similar to
335  *	MLME-DEAUTHENTICATION.request and MLME-DEAUTHENTICATE.indication
336  *	primitives).
337  * @NL80211_CMD_DISASSOCIATE: disassociation request and notification; like
338  *	NL80211_CMD_AUTHENTICATE but for Disassociation frames (similar to
339  *	MLME-DISASSOCIATE.request and MLME-DISASSOCIATE.indication primitives).
340  *
341  * @NL80211_CMD_MICHAEL_MIC_FAILURE: notification of a locally detected Michael
342  *	MIC (part of TKIP) failure; sent on the "mlme" multicast group; the
343  *	event includes %NL80211_ATTR_MAC to describe the source MAC address of
344  *	the frame with invalid MIC, %NL80211_ATTR_KEY_TYPE to show the key
345  *	type, %NL80211_ATTR_KEY_IDX to indicate the key identifier, and
346  *	%NL80211_ATTR_KEY_SEQ to indicate the TSC value of the frame; this
347  *	event matches with MLME-MICHAELMICFAILURE.indication() primitive
348  *
349  * @NL80211_CMD_JOIN_IBSS: Join a new IBSS -- given at least an SSID and a
350  *	FREQ attribute (for the initial frequency if no peer can be found)
351  *	and optionally a MAC (as BSSID) and FREQ_FIXED attribute if those
352  *	should be fixed rather than automatically determined. Can only be
353  *	executed on a network interface that is UP, and fixed BSSID/FREQ
354  *	may be rejected. Another optional parameter is the beacon interval,
355  *	given in the %NL80211_ATTR_BEACON_INTERVAL attribute, which if not
356  *	given defaults to 100 TU (102.4ms).
357  * @NL80211_CMD_LEAVE_IBSS: Leave the IBSS -- no special arguments, the IBSS is
358  *	determined by the network interface.
359  *
360  * @NL80211_CMD_TESTMODE: testmode command, takes a wiphy (or ifindex) attribute
361  *	to identify the device, and the TESTDATA blob attribute to pass through
362  *	to the driver.
363  *
364  * @NL80211_CMD_CONNECT: connection request and notification; this command
365  *	requests to connect to a specified network but without separating
366  *	auth and assoc steps. For this, you need to specify the SSID in a
367  *	%NL80211_ATTR_SSID attribute, and can optionally specify the association
368  *	IEs in %NL80211_ATTR_IE, %NL80211_ATTR_AUTH_TYPE, %NL80211_ATTR_MAC,
369  *	%NL80211_ATTR_WIPHY_FREQ, %NL80211_ATTR_CONTROL_PORT,
370  *	%NL80211_ATTR_CONTROL_PORT_ETHERTYPE and
371  *	%NL80211_ATTR_CONTROL_PORT_NO_ENCRYPT.
372  *	Background scan period can optionally be
373  *	specified in %NL80211_ATTR_BG_SCAN_PERIOD,
374  *	if not specified default background scan configuration
375  *	in driver is used and if period value is 0, bg scan will be disabled.
376  *	This attribute is ignored if driver does not support roam scan.
377  *	It is also sent as an event, with the BSSID and response IEs when the
378  *	connection is established or failed to be established. This can be
379  *	determined by the STATUS_CODE attribute.
380  * @NL80211_CMD_ROAM: request that the card roam (currently not implemented),
381  *	sent as an event when the card/driver roamed by itself.
382  * @NL80211_CMD_DISCONNECT: drop a given connection; also used to notify
383  *	userspace that a connection was dropped by the AP or due to other
384  *	reasons, for this the %NL80211_ATTR_DISCONNECTED_BY_AP and
385  *	%NL80211_ATTR_REASON_CODE attributes are used.
386  *
387  * @NL80211_CMD_SET_WIPHY_NETNS: Set a wiphy's netns. Note that all devices
388  *	associated with this wiphy must be down and will follow.
389  *
390  * @NL80211_CMD_REMAIN_ON_CHANNEL: Request to remain awake on the specified
391  *	channel for the specified amount of time. This can be used to do
392  *	off-channel operations like transmit a Public Action frame and wait for
393  *	a response while being associated to an AP on another channel.
394  *	%NL80211_ATTR_IFINDEX is used to specify which interface (and thus
395  *	radio) is used. %NL80211_ATTR_WIPHY_FREQ is used to specify the
396  *	frequency for the operation and %NL80211_ATTR_WIPHY_CHANNEL_TYPE may be
397  *	optionally used to specify additional channel parameters.
398  *	%NL80211_ATTR_DURATION is used to specify the duration in milliseconds
399  *	to remain on the channel. This command is also used as an event to
400  *	notify when the requested duration starts (it may take a while for the
401  *	driver to schedule this time due to other concurrent needs for the
402  *	radio).
403  *	When called, this operation returns a cookie (%NL80211_ATTR_COOKIE)
404  *	that will be included with any events pertaining to this request;
405  *	the cookie is also used to cancel the request.
406  * @NL80211_CMD_CANCEL_REMAIN_ON_CHANNEL: This command can be used to cancel a
407  *	pending remain-on-channel duration if the desired operation has been
408  *	completed prior to expiration of the originally requested duration.
409  *	%NL80211_ATTR_WIPHY or %NL80211_ATTR_IFINDEX is used to specify the
410  *	radio. The %NL80211_ATTR_COOKIE attribute must be given as well to
411  *	uniquely identify the request.
412  *	This command is also used as an event to notify when a requested
413  *	remain-on-channel duration has expired.
414  *
415  * @NL80211_CMD_SET_TX_BITRATE_MASK: Set the mask of rates to be used in TX
416  *	rate selection. %NL80211_ATTR_IFINDEX is used to specify the interface
417  *	and @NL80211_ATTR_TX_RATES the set of allowed rates.
418  *
419  * @NL80211_CMD_REGISTER_FRAME: Register for receiving certain mgmt frames
420  *	(via @NL80211_CMD_FRAME) for processing in userspace. This command
421  *	requires an interface index, a frame type attribute (optional for
422  *	backward compatibility reasons, if not given assumes action frames)
423  *	and a match attribute containing the first few bytes of the frame
424  *	that should match, e.g. a single byte for only a category match or
425  *	four bytes for vendor frames including the OUI. The registration
426  *	cannot be dropped, but is removed automatically when the netlink
427  *	socket is closed. Multiple registrations can be made.
428  * @NL80211_CMD_REGISTER_ACTION: Alias for @NL80211_CMD_REGISTER_FRAME for
429  *	backward compatibility
430  * @NL80211_CMD_FRAME: Management frame TX request and RX notification. This
431  *	command is used both as a request to transmit a management frame and
432  *	as an event indicating reception of a frame that was not processed in
433  *	kernel code, but is for us (i.e., which may need to be processed in a
434  *	user space application). %NL80211_ATTR_FRAME is used to specify the
435  *	frame contents (including header). %NL80211_ATTR_WIPHY_FREQ (and
436  *	optionally %NL80211_ATTR_WIPHY_CHANNEL_TYPE) is used to indicate on
437  *	which channel the frame is to be transmitted or was received. If this
438  *	channel is not the current channel (remain-on-channel or the
439  *	operational channel) the device will switch to the given channel and
440  *	transmit the frame, optionally waiting for a response for the time
441  *	specified using %NL80211_ATTR_DURATION. When called, this operation
442  *	returns a cookie (%NL80211_ATTR_COOKIE) that will be included with the
443  *	TX status event pertaining to the TX request.
444  *	%NL80211_ATTR_TX_NO_CCK_RATE is used to decide whether to send the
445  *	management frames at CCK rate or not in 2GHz band.
446  * @NL80211_CMD_FRAME_WAIT_CANCEL: When an off-channel TX was requested, this
447  *	command may be used with the corresponding cookie to cancel the wait
448  *	time if it is known that it is no longer necessary.
449  * @NL80211_CMD_ACTION: Alias for @NL80211_CMD_FRAME for backward compatibility.
450  * @NL80211_CMD_FRAME_TX_STATUS: Report TX status of a management frame
451  *	transmitted with %NL80211_CMD_FRAME. %NL80211_ATTR_COOKIE identifies
452  *	the TX command and %NL80211_ATTR_FRAME includes the contents of the
453  *	frame. %NL80211_ATTR_ACK flag is included if the recipient acknowledged
454  *	the frame.
455  * @NL80211_CMD_ACTION_TX_STATUS: Alias for @NL80211_CMD_FRAME_TX_STATUS for
456  *	backward compatibility.
457  * @NL80211_CMD_SET_CQM: Connection quality monitor configuration. This command
458  *	is used to configure connection quality monitoring notification trigger
459  *	levels.
460  * @NL80211_CMD_NOTIFY_CQM: Connection quality monitor notification. This
461  *	command is used as an event to indicate the that a trigger level was
462  *	reached.
463  * @NL80211_CMD_SET_CHANNEL: Set the channel (using %NL80211_ATTR_WIPHY_FREQ
464  *	and %NL80211_ATTR_WIPHY_CHANNEL_TYPE) the given interface (identifed
465  *	by %NL80211_ATTR_IFINDEX) shall operate on.
466  *	In case multiple channels are supported by the device, the mechanism
467  *	with which it switches channels is implementation-defined.
468  *	When a monitor interface is given, it can only switch channel while
469  *	no other interfaces are operating to avoid disturbing the operation
470  *	of any other interfaces, and other interfaces will again take
471  *	precedence when they are used.
472  *
473  * @NL80211_CMD_SET_WDS_PEER: Set the MAC address of the peer on a WDS interface.
474  *
475  * @NL80211_CMD_JOIN_MESH: Join a mesh. The mesh ID must be given, and initial
476  *	mesh config parameters may be given.
477  * @NL80211_CMD_LEAVE_MESH: Leave the mesh network -- no special arguments, the
478  *	network is determined by the network interface.
479  *
480  * @NL80211_CMD_UNPROT_DEAUTHENTICATE: Unprotected deauthentication frame
481  *	notification. This event is used to indicate that an unprotected
482  *	deauthentication frame was dropped when MFP is in use.
483  * @NL80211_CMD_UNPROT_DISASSOCIATE: Unprotected disassociation frame
484  *	notification. This event is used to indicate that an unprotected
485  *	disassociation frame was dropped when MFP is in use.
486  *
487  * @NL80211_CMD_NEW_PEER_CANDIDATE: Notification on the reception of a
488  *      beacon or probe response from a compatible mesh peer.  This is only
489  *      sent while no station information (sta_info) exists for the new peer
490  *      candidate and when @NL80211_MESH_SETUP_USERSPACE_AUTH is set.  On
491  *      reception of this notification, userspace may decide to create a new
492  *      station (@NL80211_CMD_NEW_STATION).  To stop this notification from
493  *      reoccurring, the userspace authentication daemon may want to create the
494  *      new station with the AUTHENTICATED flag unset and maybe change it later
495  *      depending on the authentication result.
496  *
497  * @NL80211_CMD_GET_WOWLAN: get Wake-on-Wireless-LAN (WoWLAN) settings.
498  * @NL80211_CMD_SET_WOWLAN: set Wake-on-Wireless-LAN (WoWLAN) settings.
499  *	Since wireless is more complex than wired ethernet, it supports
500  *	various triggers. These triggers can be configured through this
501  *	command with the %NL80211_ATTR_WOWLAN_TRIGGERS attribute. For
502  *	more background information, see
503  *	http://wireless.kernel.org/en/users/Documentation/WoWLAN.
504  *
505  * @NL80211_CMD_SET_REKEY_OFFLOAD: This command is used give the driver
506  *	the necessary information for supporting GTK rekey offload. This
507  *	feature is typically used during WoWLAN. The configuration data
508  *	is contained in %NL80211_ATTR_REKEY_DATA (which is nested and
509  *	contains the data in sub-attributes). After rekeying happened,
510  *	this command may also be sent by the driver as an MLME event to
511  *	inform userspace of the new replay counter.
512  *
513  * @NL80211_CMD_PMKSA_CANDIDATE: This is used as an event to inform userspace
514  *	of PMKSA caching dandidates.
515  *
516  * @NL80211_CMD_TDLS_OPER: Perform a high-level TDLS command (e.g. link setup).
517  * @NL80211_CMD_TDLS_MGMT: Send a TDLS management frame.
518  *
519  * @NL80211_CMD_UNEXPECTED_FRAME: Used by an application controlling an AP
520  *	(or GO) interface (i.e. hostapd) to ask for unexpected frames to
521  *	implement sending deauth to stations that send unexpected class 3
522  *	frames. Also used as the event sent by the kernel when such a frame
523  *	is received.
524  *	For the event, the %NL80211_ATTR_MAC attribute carries the TA and
525  *	other attributes like the interface index are present.
526  *	If used as the command it must have an interface index and you can
527  *	only unsubscribe from the event by closing the socket. Subscription
528  *	is also for %NL80211_CMD_UNEXPECTED_4ADDR_FRAME events.
529  *
530  * @NL80211_CMD_UNEXPECTED_4ADDR_FRAME: Sent as an event indicating that the
531  *	associated station identified by %NL80211_ATTR_MAC sent a 4addr frame
532  *	and wasn't already in a 4-addr VLAN. The event will be sent similarly
533  *	to the %NL80211_CMD_UNEXPECTED_FRAME event, to the same listener.
534  *
535  * @NL80211_CMD_PROBE_CLIENT: Probe an associated station on an AP interface
536  *	by sending a null data frame to it and reporting when the frame is
537  *	acknowleged. This is used to allow timing out inactive clients. Uses
538  *	%NL80211_ATTR_IFINDEX and %NL80211_ATTR_MAC. The command returns a
539  *	direct reply with an %NL80211_ATTR_COOKIE that is later used to match
540  *	up the event with the request. The event includes the same data and
541  *	has %NL80211_ATTR_ACK set if the frame was ACKed.
542  *
543  * @NL80211_CMD_REGISTER_BEACONS: Register this socket to receive beacons from
544  *	other BSSes when any interfaces are in AP mode. This helps implement
545  *	OLBC handling in hostapd. Beacons are reported in %NL80211_CMD_FRAME
546  *	messages. Note that per PHY only one application may register.
547  *
548  * @NL80211_CMD_SET_NOACK_MAP: sets a bitmap for the individual TIDs whether
549  *      No Acknowledgement Policy should be applied.
550  *
551  * @NL80211_CMD_MAX: highest used command number
552  * @__NL80211_CMD_AFTER_LAST: internal use

1061  *	See &enum nl80211_key_default_types.
1062  *
1063  * @NL80211_ATTR_MESH_SETUP: Optional mesh setup parameters.  These cannot be
1064  *	changed once the mesh is active.
1065  * @NL80211_ATTR_MESH_CONFIG: Mesh configuration parameters, a nested attribute
1066  *	containing attributes from &enum nl80211_meshconf_params.
1067  * @NL80211_ATTR_SUPPORT_MESH_AUTH: Currently, this means the underlying driver
1068  *	allows auth frames in a mesh to be passed to userspace for processing via
1069  *	the @NL80211_MESH_SETUP_USERSPACE_AUTH flag.
1070  * @NL80211_ATTR_STA_PLINK_STATE: The state of a mesh peer link as
1071  *	defined in &enum nl80211_plink_state. Used when userspace is
1072  *	driving the peer link management state machine.
1073  *	@NL80211_MESH_SETUP_USERSPACE_AMPE must be enabled.
1074  *
1075  * @NL80211_ATTR_WOWLAN_TRIGGERS_SUPPORTED: indicates, as part of the wiphy
1076  *	capabilities, the supported WoWLAN triggers
1077  * @NL80211_ATTR_WOWLAN_TRIGGERS: used by %NL80211_CMD_SET_WOWLAN to
1078  *	indicate which WoW triggers should be enabled. This is also
1079  *	used by %NL80211_CMD_GET_WOWLAN to get the currently enabled WoWLAN
1080  *	triggers.
1081 
1082  * @NL80211_ATTR_SCHED_SCAN_INTERVAL: Interval between scheduled scan
1083  *	cycles, in msecs.
1084 
1085  * @NL80211_ATTR_SCHED_SCAN_MATCH: Nested attribute with one or more
1086  *	sets of attributes to match during scheduled scans.  Only BSSs
1087  *	that match any of the sets will be reported.  These are
1088  *	pass-thru filter rules.
1089  *	For a match to succeed, the BSS must match all attributes of a
1090  *	set.  Since not every hardware supports matching all types of
1091  *	attributes, there is no guarantee that the reported BSSs are
1092  *	fully complying with the match sets and userspace needs to be
1093  *	able to ignore them by itself.
1094  *	Thus, the implementation is somewhat hardware-dependent, but
1095  *	this is only an optimization and the userspace application
1096  *	needs to handle all the non-filtered results anyway.
1097  *	If the match attributes don't make sense when combined with
1098  *	the values passed in @NL80211_ATTR_SCAN_SSIDS (eg. if an SSID
1099  *	is included in the probe request, but the match attributes
1100  *	will never let it go through), -EINVAL may be returned.
1101  *	If ommited, no filtering is done.
1102  *
1103  * @NL80211_ATTR_INTERFACE_COMBINATIONS: Nested attribute listing the supported
1104  *	interface combinations. In each nested item, it contains attributes
1105  *	defined in &enum nl80211_if_combination_attrs.
1106  * @NL80211_ATTR_SOFTWARE_IFTYPES: Nested attribute (just like
1107  *	%NL80211_ATTR_SUPPORTED_IFTYPES) containing the interface types that
1108  *	are managed in software: interfaces of these types aren't subject to
1109  *	any restrictions in their number or combinations.
1110  *
1111  * @%NL80211_ATTR_REKEY_DATA: nested attribute containing the information
1112  *	necessary for GTK rekeying in the device, see &enum nl80211_rekey_data.
1113  *
1114  * @NL80211_ATTR_SCAN_SUPP_RATES: rates per to be advertised as supported in scan,
1115  *	nested array attribute containing an entry for each band, with the entry
1116  *	being a list of supported rates as defined by IEEE 802.11 7.3.2.2 but
1117  *	without the length restriction (at most %NL80211_MAX_SUPP_RATES).
1118  *
1119  * @NL80211_ATTR_HIDDEN_SSID: indicates whether SSID is to be hidden from Beacon
1120  *	and Probe Response (when response to wildcard Probe Request); see

1122  *
1123  * @NL80211_ATTR_IE_PROBE_RESP: Information element(s) for Probe Response frame.
1124  *	This is used with %NL80211_CMD_NEW_BEACON and %NL80211_CMD_SET_BEACON to
1125  *	provide extra IEs (e.g., WPS/P2P IE) into Probe Response frames when the
1126  *	driver (or firmware) replies to Probe Request frames.
1127  * @NL80211_ATTR_IE_ASSOC_RESP: Information element(s) for (Re)Association
1128  *	Response frames. This is used with %NL80211_CMD_NEW_BEACON and
1129  *	%NL80211_CMD_SET_BEACON to provide extra IEs (e.g., WPS/P2P IE) into
1130  *	(Re)Association Response frames when the driver (or firmware) replies to
1131  *	(Re)Association Request frames.
1132  *
1133  * @NL80211_ATTR_STA_WME: Nested attribute containing the wme configuration
1134  *	of the station, see &enum nl80211_sta_wme_attr.
1135  * @NL80211_ATTR_SUPPORT_AP_UAPSD: the device supports uapsd when working
1136  *	as AP.

1140  *
1141  * @NL80211_ATTR_PMKSA_CANDIDATE: Nested attribute containing the PMKSA caching
1142  *	candidate information, see &enum nl80211_pmksa_candidate_attr.
1143  *
1144  * @NL80211_ATTR_TX_NO_CCK_RATE: Indicates whether to use CCK rate or not
1145  *	for management frames transmission. In order to avoid p2p probe/action
1146  *	frames are being transmitted at CCK rate in 2GHz band, the user space
1147  *	applications use this attribute.
1148  *	This attribute is used with %NL80211_CMD_TRIGGER_SCAN and
1149  *	%NL80211_CMD_FRAME commands.
1150  *
1151  * @NL80211_ATTR_TDLS_ACTION: Low level TDLS action code (e.g. link setup
1152  *	request, link setup confirm, link teardown, etc.). Values are
1153  *	described in the TDLS (802.11z) specification.
1154  * @NL80211_ATTR_TDLS_DIALOG_TOKEN: Non-zero token for uniquely identifying a
1155  *	TDLS conversation between two devices.

1159  *	as a TDLS peer sta.
1160  * @NL80211_ATTR_TDLS_EXTERNAL_SETUP: The TDLS discovery/setup and teardown
1161  *	procedures should be performed by sending TDLS packets via
1162  *	%NL80211_CMD_TDLS_MGMT. Otherwise %NL80211_CMD_TDLS_OPER should be
1163  *	used for asking the driver to perform a TDLS operation.
1164  *
1165  * @NL80211_ATTR_DEVICE_AP_SME: This u32 attribute may be listed for devices
1166  *	that have AP support to indicate that they have the AP SME integrated
1167  *	with support for the features listed in this attribute, see
1168  *	&enum nl80211_ap_sme_features.
1169  *
1170  * @NL80211_ATTR_DONT_WAIT_FOR_ACK: Used with %NL80211_CMD_FRAME, this tells
1171  *	the driver to not wait for an acknowledgement. Note that due to this,
1172  *	it will also not give a status callback nor return a cookie. This is
1173  *	mostly useful for probe responses to save airtime.
1174  *
1175  * @NL80211_ATTR_FEATURE_FLAGS: This u32 attribute contains flags from
1176  *	&enum nl80211_feature_flags and is advertised in wiphy information.
1177  * @NL80211_ATTR_PROBE_RESP_OFFLOAD: Indicates that the HW responds to probe
1178  *
1179  *	requests while operating in AP-mode.
1180  *	This attribute holds a bitmap of the supported protocols for
1181  *	offloading (see &enum nl80211_probe_resp_offload_support_attr).
1182  *
1183  * @NL80211_ATTR_PROBE_RESP: Probe Response template data. Contains the entire
1184  *	probe-response frame. The DA field in the 802.11 header is zero-ed out,
1185  *	to be filled by the FW.
1186  * @NL80211_ATTR_DISABLE_HT:  Force HT capable interfaces to disable
1187  *      this feature.  Currently, only supported in mac80211 drivers.
1188  * @NL80211_ATTR_HT_CAPABILITY_MASK: Specify which bits of the
1189  *      ATTR_HT_CAPABILITY to which attention should be paid.
1190  *      Currently, only mac80211 NICs support this feature.
1191  *      The values that may be configured are:
1192  *       MCS rates, MAX-AMSDU, HT-20-40 and HT_CAP_SGI_40
1193  *       AMPDU density and AMPDU factor.
1194  *      All values are treated as suggestions and may be ignored
1195  *      by the driver as required.  The actual values may be seen in
1196  *      the station debugfs ht_caps file.
1197  *
1198  * @NL80211_ATTR_DFS_REGION: region for regulatory rules which this country
1199  *    abides to when initiating radiation on DFS channels. A country maps

1203  *      up to 16 TIDs.
1204  *
1205  * @NL80211_ATTR_INACTIVITY_TIMEOUT: timeout value in seconds, this can be
1206  *	used by the drivers which has MLME in firmware and does not have support
1207  *	to report per station tx/rx activity to free up the staion entry from
1208  *	the list. This needs to be used when the driver advertises the
1209  *	capability to timeout the stations.
1210  *
1211  * @NL80211_ATTR_RX_SIGNAL_DBM: signal strength in dBm (as a 32-bit int);
1212  *	this attribute is (depending on the driver capabilities) added to

1214  *
1215  * @NL80211_ATTR_BG_SCAN_PERIOD: Background scan period in seconds
1216  *      or 0 to disable background scan.
