32 /**
33  * DOC: Station handling
34  *
35  * Stations are added per interface, but a special case exists with VLAN
36  * interfaces. When a station is bound to an AP interface, it may be moved
37  * into a VLAN identified by a VLAN interface index (%NL80211_ATTR_STA_VLAN).
38  * The station is still assumed to belong to the AP interface it was added
39  * to.
40  *
41  * Station handling varies per interface type and depending on the driver's
42  * capabilities.
43  *
44  * For drivers supporting TDLS with external setup (WIPHY_FLAG_SUPPORTS_TDLS
45  * and WIPHY_FLAG_TDLS_EXTERNAL_SETUP), the station lifetime is as follows:
46  *  - a setup station entry is added, not yet authorized, without any rate
47  *    or capability information, this just exists to avoid race conditions
48  *  - when the TDLS setup is done, a single NL80211_CMD_SET_STATION is valid
49  *    to add rate and capability information to the station and at the same
50  *    time mark it authorized.
51  *  - %NL80211_TDLS_ENABLE_LINK is then used
52  *  - after this, the only valid operation is to remove it by tearing down
53  *    the TDLS link (%NL80211_TDLS_DISABLE_LINK)

58 /**
59  * DOC: Frame transmission/registration support
60  *
61  * Frame transmission and registration support exists to allow userspace
62  * management entities such as wpa_supplicant react to management frames
63  * that are not being handled by the kernel. This includes, for example,
64  * certain classes of action frames that cannot be handled in the kernel
65  * for various reasons.
66  *
67  * Frame registration is done on a per-interface basis and registrations
68  * cannot be removed other than by closing the socket. It is possible to
69  * specify a registration filter to register, for example, only for a
70  * certain type of action frame. In particular with action frames, those
71  * that userspace registers for will not be returned as unhandled by the
72  * driver, so that the registered application has to take responsibility
73  * for doing that.
74  *
75  * The type of frame that can be registered for is also dependent on the
76  * driver and interface type. The frame types are advertised in wiphy
77  * attributes so applications know what to expect.
78  *
79  * NOTE: When an interface changes type while registrations are active,
80  *       these registrations are ignored until the interface type is
81  *       changed again. This means that changing the interface type can
82  *       lead to a situation that couldn't otherwise be produced, but
83  *       any such registrations will be dormant in the sense that they
84  *       will not be serviced, i.e. they will not receive any frames.
85  *
86  * Frame transmission allows userspace to send for example the required
87  * responses to action frames. It is subject to some sanity checking,
88  * but many frames can be transmitted. When a frame was transmitted, its
89  * status is indicated to the sending socket.
90  *
91  * For more technical details, see the corresponding command descriptions
92  * below.

95 /**
96  * DOC: Virtual interface / concurrency capabilities
97  *
98  * Some devices are able to operate with virtual MACs, they can have
99  * more than one virtual interface. The capability handling for this
100  * is a bit complex though, as there may be a number of restrictions
101  * on the types of concurrency that are supported.
102  *
103  * To start with, each device supports the interface types listed in
104  * the %NL80211_ATTR_SUPPORTED_IFTYPES attribute, but by listing the
105  * types there no concurrency is implied.
106  *
107  * Once concurrency is desired, more attributes must be observed:
108  * To start with, since some interface types are purely managed in
109  * software, like the AP-VLAN type in mac80211 for example, there's
110  * an additional list of these, they can be added at any time and
111  * are only restricted by some semantic restrictions (e.g. AP-VLAN
112  * cannot be added without a corresponding AP interface). This list
113  * is exported in the %NL80211_ATTR_SOFTWARE_IFTYPES attribute.
114  *
115  * Further, the list of supported combinations is exported. This is
116  * in the %NL80211_ATTR_INTERFACE_COMBINATIONS attribute. Basically,
117  * it exports a list of "groups", and at any point in time the
118  * interfaces that are currently active must fall into any one of
119  * the advertised groups. Within each group, there are restrictions
120  * on the number of interfaces of different types that are supported
121  * and also the number of different channels, along with potentially
122  * some other restrictions. See &enum nl80211_if_combination_attrs.
123  *
124  * All together, these attributes define the concurrency of virtual
125  * interfaces that a given device supports.

128 /**
129  * DOC: packet coalesce support
130  *
131  * In most cases, host that receives IPv4 and IPv6 multicast/broadcast
132  * packets does not do anything with these packets. Therefore the
133  * reception of these unwanted packets causes unnecessary processing
134  * and power consumption.
135  *
136  * Packet coalesce feature helps to reduce number of received interrupts
137  * to host by buffering these packets in firmware/hardware for some
138  * predefined time. Received interrupt will be generated when one of the
139  * following events occur.
140  * a) Expiration of hardware timer whose expiration time is set to maximum
141  * coalescing delay of matching coalesce rule.
142  * b) Coalescing buffer in hardware reaches it's limit.
143  * c) Packet doesn't match any of the configured coalesce rules.
144  *
145  * User needs to configure following parameters for creating a coalesce
146  * rule.
147  * a) Maximum coalescing delay
148  * b) List of packet patterns which needs to be matched
149  * c) Condition for coalescence. pattern 'match' or 'no match'
150  * Multiple such rules can be created.

273  *	interface is identified with %NL80211_ATTR_IFINDEX and the management
274  *	frame subtype with %NL80211_ATTR_MGMT_SUBTYPE. The extra IE data to be
275  *	added to the end of the specified management frame is specified with
276  *	%NL80211_ATTR_IE. If the command succeeds, the requested data will be
277  *	added to all specified management frames generated by
278  *	kernel/firmware/driver.
279  *	Note: This command has been removed and it is only reserved at this
280  *	point to avoid re-using existing command number. The functionality this

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

1312  *	sets of attributes to match during scheduled scans.  Only BSSs
1313  *	that match any of the sets will be reported.  These are
1314  *	pass-thru filter rules.
1315  *	For a match to succeed, the BSS must match all attributes of a
1316  *	set.  Since not every hardware supports matching all types of
1317  *	attributes, there is no guarantee that the reported BSSs are
1318  *	fully complying with the match sets and userspace needs to be
1319  *	able to ignore them by itself.
1320  *	Thus, the implementation is somewhat hardware-dependent, but
1321  *	this is only an optimization and the userspace application
1322  *	needs to handle all the non-filtered results anyway.
1323  *	If the match attributes don't make sense when combined with
1324  *	the values passed in @NL80211_ATTR_SCAN_SSIDS (eg. if an SSID
1325  *	is included in the probe request, but the match attributes

1371  *	for management frames transmission. In order to avoid p2p probe/action
1372  *	frames are being transmitted at CCK rate in 2GHz band, the user space
1373  *	applications use this attribute.
1374  *	This attribute is used with %NL80211_CMD_TRIGGER_SCAN and

1396  * @NL80211_ATTR_DONT_WAIT_FOR_ACK: Used with %NL80211_CMD_FRAME, this tells
1397  *	the driver to not wait for an acknowledgement. Note that due to this,
1398  *	it will also not give a status callback nor return a cookie. This is
1399  *	mostly useful for probe responses to save airtime.

3457  * DOC: TCP connection wakeup
3458  *
3459  * Some devices can establish a TCP connection in order to be woken up by a
3460  * packet coming in from outside their network segment, or behind NAT. If
3461  * configured, the device will establish a TCP connection to the given
3462  * service, and periodically send data to that service. The first data
3463  * packet is usually transmitted after SYN/ACK, also ACKing the SYN/ACK.
3464  * The data packets can optionally include a (little endian) sequence
3465  * number (in the TCP payload!) that is generated by the device, and, also
3466  * optionally, a token from a list of tokens. This serves as a keep-alive
3467  * with the service, and for NATed connections, etc.
3468  *
3469  * During this keep-alive period, the server doesn't send any data to the
3470  * client. When receiving data, it is compared against the wakeup pattern
3471  * (and mask) and if it matches, the host is woken up. Similarly, if the
3472  * connection breaks or cannot be established to start with, the host is
3473  * also woken up.
3474  *
3475  * Developer's note: ARP offload is required for this, otherwise TCP
3476  * response packets might not go through correctly.
