55  * DOC: Station handling
56  *
57  * Stations are added per interface, but a special case exists with VLAN
58  * interfaces. When a station is bound to an AP interface, it may be moved
59  * into a VLAN identified by a VLAN interface index (%NL80211_ATTR_STA_VLAN).
60  * The station is still assumed to belong to the AP interface it was added
61  * to.
62  *
63  * Station handling varies per interface type and depending on the driver's
64  * capabilities.
65  *
66  * For drivers supporting TDLS with external setup (WIPHY_FLAG_SUPPORTS_TDLS
67  * and WIPHY_FLAG_TDLS_EXTERNAL_SETUP), the station lifetime is as follows:
68  *  - a setup station entry is added, not yet authorized, without any rate
69  *    or capability information, this just exists to avoid race conditions
70  *  - when the TDLS setup is done, a single NL80211_CMD_SET_STATION is valid
71  *    to add rate and capability information to the station and at the same
72  *    time mark it authorized.
73  *  - %NL80211_TDLS_ENABLE_LINK is then used
74  *  - after this, the only valid operation is to remove it by tearing down
75  *    the TDLS link (%NL80211_TDLS_DISABLE_LINK)

80 /**
81  * DOC: Frame transmission/registration support
82  *
83  * Frame transmission and registration support exists to allow userspace
84  * management entities such as wpa_supplicant react to management frames
85  * that are not being handled by the kernel. This includes, for example,
86  * certain classes of action frames that cannot be handled in the kernel
87  * for various reasons.
88  *
89  * Frame registration is done on a per-interface basis and registrations
90  * cannot be removed other than by closing the socket. It is possible to
91  * specify a registration filter to register, for example, only for a
92  * certain type of action frame. In particular with action frames, those
93  * that userspace registers for will not be returned as unhandled by the
94  * driver, so that the registered application has to take responsibility
95  * for doing that.
96  *
97  * The type of frame that can be registered for is also dependent on the
98  * driver and interface type. The frame types are advertised in wiphy
99  * attributes so applications know what to expect.
100  *
101  * NOTE: When an interface changes type while registrations are active,
102  *       these registrations are ignored until the interface type is
103  *       changed again. This means that changing the interface type can
104  *       lead to a situation that couldn't otherwise be produced, but
105  *       any such registrations will be dormant in the sense that they
106  *       will not be serviced, i.e. they will not receive any frames.
107  *
108  * Frame transmission allows userspace to send for example the required
109  * responses to action frames. It is subject to some sanity checking,
110  * but many frames can be transmitted. When a frame was transmitted, its
111  * status is indicated to the sending socket.
112  *
113  * For more technical details, see the corresponding command descriptions
114  * below.

117 /**
118  * DOC: Virtual interface / concurrency capabilities
119  *
120  * Some devices are able to operate with virtual MACs, they can have
121  * more than one virtual interface. The capability handling for this
122  * is a bit complex though, as there may be a number of restrictions
123  * on the types of concurrency that are supported.
124  *
125  * To start with, each device supports the interface types listed in
126  * the %NL80211_ATTR_SUPPORTED_IFTYPES attribute, but by listing the
127  * types there no concurrency is implied.
128  *
129  * Once concurrency is desired, more attributes must be observed:
130  * To start with, since some interface types are purely managed in
131  * software, like the AP-VLAN type in mac80211 for example, there's
132  * an additional list of these, they can be added at any time and
133  * are only restricted by some semantic restrictions (e.g. AP-VLAN
134  * cannot be added without a corresponding AP interface). This list
135  * is exported in the %NL80211_ATTR_SOFTWARE_IFTYPES attribute.
136  *
137  * Further, the list of supported combinations is exported. This is
138  * in the %NL80211_ATTR_INTERFACE_COMBINATIONS attribute. Basically,
139  * it exports a list of "groups", and at any point in time the
140  * interfaces that are currently active must fall into any one of
141  * the advertised groups. Within each group, there are restrictions
142  * on the number of interfaces of different types that are supported
143  * and also the number of different channels, along with potentially
144  * some other restrictions. See &enum nl80211_if_combination_attrs.
145  *
146  * All together, these attributes define the concurrency of virtual
147  * interfaces that a given device supports.

151  * DOC: packet coalesce support
152  *
153  * In most cases, host that receives IPv4 and IPv6 multicast/broadcast
154  * packets does not do anything with these packets. Therefore the
155  * reception of these unwanted packets causes unnecessary processing
156  * and power consumption.
157  *
158  * Packet coalesce feature helps to reduce number of received interrupts
159  * to host by buffering these packets in firmware/hardware for some
160  * predefined time. Received interrupt will be generated when one of the
161  * following events occur.
162  * a) Expiration of hardware timer whose expiration time is set to maximum
163  * coalescing delay of matching coalesce rule.
164  * b) Coalescing buffer in hardware reaches it's limit.
165  * c) Packet doesn't match any of the configured coalesce rules.
166  *
167  * User needs to configure following parameters for creating a coalesce
168  * rule.
169  * a) Maximum coalescing delay
170  * b) List of packet patterns which needs to be matched
171  * c) Condition for coalescence. pattern 'match' or 'no match'
172  * Multiple such rules can be created.

185  *
186  * Similarly @NL80211_EXT_FEATURE_4WAY_HANDSHAKE_STA_1X flag can be

209  *	%NL80211_ATTR_FILS_ERP_NEXT_SEQ_NUM - used to construct erp message
210  *	%NL80211_ATTR_FILS_ERP_RRK - used to generate the rIK and rMSK
211  * rIK should be used to generate an authentication tag on the ERP message and
212  * rMSK should be used to derive a PMKSA.
213  * rIK, rMSK should be generated and keyname_nai, sequence number should be used
214  * as specified in IETF RFC 6696.
215  *
216  * When FILS shared key authentication is completed, driver needs to provide the
217  * below additional parameters to userspace.
218  *	%NL80211_ATTR_FILS_KEK - used for key renewal
219  *	%NL80211_ATTR_FILS_ERP_NEXT_SEQ_NUM - used in further EAP-RP exchanges
220  *	%NL80211_ATTR_PMKID - used to identify the PMKSA used/generated
221  *	%Nl80211_ATTR_PMK - used to update PMKSA cache in userspace
222  * The PMKSA can be maintained in userspace persistently so that it can be used
223  * later after reboots or wifi turn off/on also.

368  * @NL80211_CMD_SET_MGMT_EXTRA_IE: Set extra IEs for management frames. The
369  *	interface is identified with %NL80211_ATTR_IFINDEX and the management
370  *	frame subtype with %NL80211_ATTR_MGMT_SUBTYPE. The extra IE data to be
371  *	added to the end of the specified management frame is specified with
372  *	%NL80211_ATTR_IE. If the command succeeds, the requested data will be
373  *	added to all specified management frames generated by
374  *	kernel/firmware/driver.
375  *	Note: This command has been removed and it is only reserved at this
376  *	point to avoid re-using existing command number. The functionality this
377  *	command was planned for has been provided with cleaner design with the
378  *	option to specify additional IEs in NL80211_CMD_TRIGGER_SCAN,
379  *	NL80211_CMD_AUTHENTICATE, NL80211_CMD_ASSOCIATE,
380  *	NL80211_CMD_DEAUTHENTICATE, and NL80211_CMD_DISASSOCIATE.
381  *
382  * @NL80211_CMD_GET_SCAN: get scan results
383  * @NL80211_CMD_TRIGGER_SCAN: trigger a new scan with the given parameters
384  *	%NL80211_ATTR_TX_NO_CCK_RATE is used to decide whether to send the
385  *	probe requests at CCK rate or not. %NL80211_ATTR_BSSID can be used to
386  *	specify a BSSID to scan for; if not included, the wildcard BSSID will
387  *	be used.
388  * @NL80211_CMD_NEW_SCAN_RESULTS: scan notification (as a reply to
389  *	NL80211_CMD_GET_SCAN and on the "scan" multicast group)
390  * @NL80211_CMD_SCAN_ABORTED: scan was aborted, for unspecified reasons,
391  *	partial scan results may be available
392  *
393  * @NL80211_CMD_START_SCHED_SCAN: start a scheduled scan at certain
394  *	intervals and certain number of cycles, as specified by
395  *	%NL80211_ATTR_SCHED_SCAN_PLANS. If %NL80211_ATTR_SCHED_SCAN_PLANS is
396  *	not specified and only %NL80211_ATTR_SCHED_SCAN_INTERVAL is specified,
397  *	scheduled scan will run in an infinite loop with the specified interval.
398  *	These attributes are mutually exculsive,
399  *	i.e. NL80211_ATTR_SCHED_SCAN_INTERVAL must not be passed if
400  *	NL80211_ATTR_SCHED_SCAN_PLANS is defined.
401  *	If for some reason scheduled scan is aborted by the driver, all scan
402  *	plans are canceled (including scan plans that did not start yet).
403  *	Like with normal scans, if SSIDs (%NL80211_ATTR_SCAN_SSIDS)
404  *	are passed, they are used in the probe requests.  For
405  *	broadcast, a broadcast SSID must be passed (ie. an empty
406  *	string).  If no SSID is passed, no probe requests are sent and
407  *	a passive scan is performed.  %NL80211_ATTR_SCAN_FREQUENCIES,
408  *	if passed, define which channels should be scanned; if not
409  *	passed, all channels allowed for the current regulatory domain
410  *	are used.  Extra IEs can also be passed from the userspace by
411  *	using the %NL80211_ATTR_IE attribute.  The first cycle of the
412  *	scheduled scan can be delayed by %NL80211_ATTR_SCHED_SCAN_DELAY
413  *	is supplied. If the device supports multiple concurrent scheduled
414  *	scans, it will allow such when the caller provides the flag attribute
415  *	%NL80211_ATTR_SCHED_SCAN_MULTI to indicate user-space support for it.
416  * @NL80211_CMD_STOP_SCHED_SCAN: stop a scheduled scan. Returns -ENOENT if
417  *	scheduled scan is not running. The caller may assume that as soon
418  *	as the call returns, it is safe to start a new scheduled scan again.
419  * @NL80211_CMD_SCHED_SCAN_RESULTS: indicates that there are scheduled scan
420  *	results available.
421  * @NL80211_CMD_SCHED_SCAN_STOPPED: indicates that the scheduled scan has
422  *	stopped.  The driver may issue this event at any time during a
423  *	scheduled scan.  One reason for stopping the scan is if the hardware
424  *	does not support starting an association or a normal scan while running
425  *	a scheduled scan.  This event is also sent when the
426  *	%NL80211_CMD_STOP_SCHED_SCAN command is received or when the interface
427  *	is brought down while a scheduled scan was running.
428  *
429  * @NL80211_CMD_GET_SURVEY: get survey resuls, e.g. channel occupation
430  *      or noise level
431  * @NL80211_CMD_NEW_SURVEY_RESULTS: survey data notification (as a reply to
432  *	NL80211_CMD_GET_SURVEY and on the "scan" multicast group)
433  *
434  * @NL80211_CMD_SET_PMKSA: Add a PMKSA cache entry using %NL80211_ATTR_MAC
435  *	(for the BSSID), %NL80211_ATTR_PMKID, and optionally %NL80211_ATTR_PMK
436  *	(PMK is used for PTKSA derivation in case of FILS shared key offload) or
437  *	using %NL80211_ATTR_SSID, %NL80211_ATTR_FILS_CACHE_ID,
438  *	%NL80211_ATTR_PMKID, and %NL80211_ATTR_PMK in case of FILS
439  *	authentication where %NL80211_ATTR_FILS_CACHE_ID is the identifier
440  *	advertized by a FILS capable AP identifying the scope of PMKSA in an
441  *	ESS.
442  * @NL80211_CMD_DEL_PMKSA: Delete a PMKSA cache entry, using %NL80211_ATTR_MAC
443  *	(for the BSSID) and %NL80211_ATTR_PMKID or using %NL80211_ATTR_SSID,
444  *	%NL80211_ATTR_FILS_CACHE_ID, and %NL80211_ATTR_PMKID in case of FILS
445  *	authentication.
446  * @NL80211_CMD_FLUSH_PMKSA: Flush all PMKSA cache entries.
447  *
448  * @NL80211_CMD_REG_CHANGE: indicates to userspace the regulatory domain
449  * 	has been changed and provides details of the request information
450  * 	that caused the change such as who initiated the regulatory request
451  * 	(%NL80211_ATTR_REG_INITIATOR), the wiphy_idx
452  * 	(%NL80211_ATTR_REG_ALPHA2) on which the request was made from if
453  * 	the initiator was %NL80211_REGDOM_SET_BY_COUNTRY_IE or
454  * 	%NL80211_REGDOM_SET_BY_DRIVER, the type of regulatory domain
455  * 	set (%NL80211_ATTR_REG_TYPE), if the type of regulatory domain is
456  * 	%NL80211_REG_TYPE_COUNTRY the alpha2 to which we have moved on
457  * 	to (%NL80211_ATTR_REG_ALPHA2).
458  * @NL80211_CMD_REG_BEACON_HINT: indicates to userspace that an AP beacon
459  * 	has been found while world roaming thus enabling active scan or
460  * 	any mode of operation that initiates TX (beacons) on a channel
461  * 	where we would not have been able to do either before. As an example
462  * 	if you are world roaming (regulatory domain set to world or if your
463  * 	driver is using a custom world roaming regulatory domain) and while
464  * 	doing a passive scan on the 5 GHz band you find an AP there (if not
465  * 	on a DFS channel) you will now be able to actively scan for that AP
466  * 	or use AP mode on your card on that same channel. Note that this will
467  * 	never be used for channels 1-11 on the 2 GHz band as they are always
468  * 	enabled world wide. This beacon hint is only sent if your device had
469  * 	either disabled active scanning or beaconing on a channel. We send to
470  * 	userspace the wiphy on which we removed a restriction from
471  * 	(%NL80211_ATTR_WIPHY) and the channel on which this occurred
472  * 	before (%NL80211_ATTR_FREQ_BEFORE) and after (%NL80211_ATTR_FREQ_AFTER)
473  * 	the beacon hint was processed.
474  *
475  * @NL80211_CMD_AUTHENTICATE: authentication request and notification.
476  *	This command is used both as a command (request to authenticate) and
477  *	as an event on the "mlme" multicast group indicating completion of the
478  *	authentication process.
479  *	When used as a command, %NL80211_ATTR_IFINDEX is used to identify the
480  *	interface. %NL80211_ATTR_MAC is used to specify PeerSTAAddress (and
481  *	BSSID in case of station mode). %NL80211_ATTR_SSID is used to specify
482  *	the SSID (mainly for association, but is included in authentication
483  *	request, too, to help BSS selection. %NL80211_ATTR_WIPHY_FREQ is used
484  *	to specify the frequence of the channel in MHz. %NL80211_ATTR_AUTH_TYPE
485  *	is used to specify the authentication type. %NL80211_ATTR_IE is used to
486  *	define IEs (VendorSpecificInfo, but also including RSN IE and FT IEs)
487  *	to be added to the frame.
488  *	When used as an event, this reports reception of an Authentication
489  *	frame in station and IBSS modes when the local MLME processed the
490  *	frame, i.e., it was for the local STA and was received in correct
491  *	state. This is similar to MLME-AUTHENTICATE.confirm primitive in the
492  *	MLME SAP interface (kernel providing MLME, userspace SME). The
493  *	included %NL80211_ATTR_FRAME attribute contains the management frame
494  *	(including both the header and frame body, but not FCS). This event is
495  *	also used to indicate if the authentication attempt timed out. In that
496  *	case the %NL80211_ATTR_FRAME attribute is replaced with a
497  *	%NL80211_ATTR_TIMED_OUT flag (and %NL80211_ATTR_MAC to indicate which
498  *	pending authentication timed out).
499  * @NL80211_CMD_ASSOCIATE: association request and notification; like
500  *	NL80211_CMD_AUTHENTICATE but for Association and Reassociation
501  *	(similar to MLME-ASSOCIATE.request, MLME-REASSOCIATE.request,
502  *	MLME-ASSOCIATE.confirm or MLME-REASSOCIATE.confirm primitives). The
503  *	%NL80211_ATTR_PREV_BSSID attribute is used to specify whether the
504  *	request is for the initial association to an ESS (that attribute not
505  *	included) or for reassociation within the ESS (that attribute is
506  *	included).
507  * @NL80211_CMD_DEAUTHENTICATE: deauthentication request and notification; like
508  *	NL80211_CMD_AUTHENTICATE but for Deauthentication frames (similar to
509  *	MLME-DEAUTHENTICATION.request and MLME-DEAUTHENTICATE.indication
510  *	primitives).
511  * @NL80211_CMD_DISASSOCIATE: disassociation request and notification; like
512  *	NL80211_CMD_AUTHENTICATE but for Disassociation frames (similar to
513  *	MLME-DISASSOCIATE.request and MLME-DISASSOCIATE.indication primitives).
514  *
515  * @NL80211_CMD_MICHAEL_MIC_FAILURE: notification of a locally detected Michael
516  *	MIC (part of TKIP) failure; sent on the "mlme" multicast group; the
517  *	event includes %NL80211_ATTR_MAC to describe the source MAC address of
518  *	the frame with invalid MIC, %NL80211_ATTR_KEY_TYPE to show the key
519  *	type, %NL80211_ATTR_KEY_IDX to indicate the key identifier, and
520  *	%NL80211_ATTR_KEY_SEQ to indicate the TSC value of the frame; this
521  *	event matches with MLME-MICHAELMICFAILURE.indication() primitive
522  *
523  * @NL80211_CMD_JOIN_IBSS: Join a new IBSS -- given at least an SSID and a
524  *	FREQ attribute (for the initial frequency if no peer can be found)
525  *	and optionally a MAC (as BSSID) and FREQ_FIXED attribute if those
526  *	should be fixed rather than automatically determined. Can only be
527  *	executed on a network interface that is UP, and fixed BSSID/FREQ
528  *	may be rejected. Another optional parameter is the beacon interval,
529  *	given in the %NL80211_ATTR_BEACON_INTERVAL attribute, which if not
530  *	given defaults to 100 TU (102.4ms).
531  * @NL80211_CMD_LEAVE_IBSS: Leave the IBSS -- no special arguments, the IBSS is
532  *	determined by the network interface.
533  *
534  * @NL80211_CMD_TESTMODE: testmode command, takes a wiphy (or ifindex) attribute
535  *	to identify the device, and the TESTDATA blob attribute to pass through
536  *	to the driver.
537  *
538  * @NL80211_CMD_CONNECT: connection request and notification; this command
539  *	requests to connect to a specified network but without separating
540  *	auth and assoc steps. For this, you need to specify the SSID in a
541  *	%NL80211_ATTR_SSID attribute, and can optionally specify the association
542  *	IEs in %NL80211_ATTR_IE, %NL80211_ATTR_AUTH_TYPE, %NL80211_ATTR_USE_MFP,
543  *	%NL80211_ATTR_MAC, %NL80211_ATTR_WIPHY_FREQ, %NL80211_ATTR_CONTROL_PORT,
544  *	%NL80211_ATTR_CONTROL_PORT_ETHERTYPE,
545  *	%NL80211_ATTR_CONTROL_PORT_NO_ENCRYPT, %NL80211_ATTR_MAC_HINT, and
546  *	%NL80211_ATTR_WIPHY_FREQ_HINT.
547  *	If included, %NL80211_ATTR_MAC and %NL80211_ATTR_WIPHY_FREQ are
548  *	restrictions on BSS selection, i.e., they effectively prevent roaming
549  *	within the ESS. %NL80211_ATTR_MAC_HINT and %NL80211_ATTR_WIPHY_FREQ_HINT
550  *	can be included to provide a recommendation of the initial BSS while
551  *	allowing the driver to roam to other BSSes within the ESS and also to
552  *	ignore this recommendation if the indicated BSS is not ideal. Only one
553  *	set of BSSID,frequency parameters is used (i.e., either the enforcing
554  *	%NL80211_ATTR_MAC,%NL80211_ATTR_WIPHY_FREQ or the less strict
555  *	%NL80211_ATTR_MAC_HINT and %NL80211_ATTR_WIPHY_FREQ_HINT).
556  *	%NL80211_ATTR_PREV_BSSID can be used to request a reassociation within
557  *	the ESS in case the device is already associated and an association with
558  *	a different BSS is desired.
559  *	Background scan period can optionally be
560  *	specified in %NL80211_ATTR_BG_SCAN_PERIOD,
561  *	if not specified default background scan configuration
562  *	in driver is used and if period value is 0, bg scan will be disabled.
563  *	This attribute is ignored if driver does not support roam scan.
564  *	It is also sent as an event, with the BSSID and response IEs when the
565  *	connection is established or failed to be established. This can be
566  *	determined by the %NL80211_ATTR_STATUS_CODE attribute (0 = success,
567  *	non-zero = failure). If %NL80211_ATTR_TIMED_OUT is included in the
568  *	event, the connection attempt failed due to not being able to initiate
569  *	authentication/association or not receiving a response from the AP.
570  *	Non-zero %NL80211_ATTR_STATUS_CODE value is indicated in that case as
571  *	well to remain backwards compatible.
572  *	When establishing a security association, drivers that support 4 way
573  *	handshake offload should send %NL80211_CMD_PORT_AUTHORIZED event when
574  *	the 4 way handshake is completed successfully.
575  * @NL80211_CMD_ROAM: Notification indicating the card/driver roamed by itself.
576  *	When a security association was established with the new AP (e.g. if
577  *	the FT protocol was used for roaming or the driver completed the 4 way
578  *	handshake), this event should be followed by an
579  *	%NL80211_CMD_PORT_AUTHORIZED event.
580  * @NL80211_CMD_DISCONNECT: drop a given connection; also used to notify
581  *	userspace that a connection was dropped by the AP or due to other
582  *	reasons, for this the %NL80211_ATTR_DISCONNECTED_BY_AP and
583  *	%NL80211_ATTR_REASON_CODE attributes are used.
584  *
585  * @NL80211_CMD_SET_WIPHY_NETNS: Set a wiphy's netns. Note that all devices
586  *	associated with this wiphy must be down and will follow.
587  *
588  * @NL80211_CMD_REMAIN_ON_CHANNEL: Request to remain awake on the specified
589  *	channel for the specified amount of time. This can be used to do
590  *	off-channel operations like transmit a Public Action frame and wait for
591  *	a response while being associated to an AP on another channel.
592  *	%NL80211_ATTR_IFINDEX is used to specify which interface (and thus
593  *	radio) is used. %NL80211_ATTR_WIPHY_FREQ is used to specify the
594  *	frequency for the operation.
595  *	%NL80211_ATTR_DURATION is used to specify the duration in milliseconds
596  *	to remain on the channel. This command is also used as an event to
597  *	notify when the requested duration starts (it may take a while for the
598  *	driver to schedule this time due to other concurrent needs for the
599  *	radio).
600  *	When called, this operation returns a cookie (%NL80211_ATTR_COOKIE)
601  *	that will be included with any events pertaining to this request;
602  *	the cookie is also used to cancel the request.
603  * @NL80211_CMD_CANCEL_REMAIN_ON_CHANNEL: This command can be used to cancel a
604  *	pending remain-on-channel duration if the desired operation has been
605  *	completed prior to expiration of the originally requested duration.
606  *	%NL80211_ATTR_WIPHY or %NL80211_ATTR_IFINDEX is used to specify the
607  *	radio. The %NL80211_ATTR_COOKIE attribute must be given as well to
608  *	uniquely identify the request.
609  *	This command is also used as an event to notify when a requested
610  *	remain-on-channel duration has expired.
611  *
612  * @NL80211_CMD_SET_TX_BITRATE_MASK: Set the mask of rates to be used in TX
613  *	rate selection. %NL80211_ATTR_IFINDEX is used to specify the interface
614  *	and @NL80211_ATTR_TX_RATES the set of allowed rates.
615  *
616  * @NL80211_CMD_REGISTER_FRAME: Register for receiving certain mgmt frames
617  *	(via @NL80211_CMD_FRAME) for processing in userspace. This command
618  *	requires an interface index, a frame type attribute (optional for
619  *	backward compatibility reasons, if not given assumes action frames)
620  *	and a match attribute containing the first few bytes of the frame
621  *	that should match, e.g. a single byte for only a category match or
622  *	four bytes for vendor frames including the OUI. The registration
623  *	cannot be dropped, but is removed automatically when the netlink
624  *	socket is closed. Multiple registrations can be made.
625  * @NL80211_CMD_REGISTER_ACTION: Alias for @NL80211_CMD_REGISTER_FRAME for
626  *	backward compatibility
627  * @NL80211_CMD_FRAME: Management frame TX request and RX notification. This
628  *	command is used both as a request to transmit a management frame and
629  *	as an event indicating reception of a frame that was not processed in
630  *	kernel code, but is for us (i.e., which may need to be processed in a
631  *	user space application). %NL80211_ATTR_FRAME is used to specify the
632  *	frame contents (including header). %NL80211_ATTR_WIPHY_FREQ is used
633  *	to indicate on which channel the frame is to be transmitted or was
634  *	received. If this channel is not the current channel (remain-on-channel
635  *	or the operational channel) the device will switch to the given channel
636  *	and transmit the frame, optionally waiting for a response for the time
637  *	specified using %NL80211_ATTR_DURATION. When called, this operation
638  *	returns a cookie (%NL80211_ATTR_COOKIE) that will be included with the
639  *	TX status event pertaining to the TX request.
640  *	%NL80211_ATTR_TX_NO_CCK_RATE is used to decide whether to send the
641  *	management frames at CCK rate or not in 2GHz band.
642  *	%NL80211_ATTR_CSA_C_OFFSETS_TX is an array of offsets to CSA
643  *	counters which will be updated to the current value. This attribute
644  *	is used during CSA period.
645  * @NL80211_CMD_FRAME_WAIT_CANCEL: When an off-channel TX was requested, this
646  *	command may be used with the corresponding cookie to cancel the wait
647  *	time if it is known that it is no longer necessary.
648  * @NL80211_CMD_ACTION: Alias for @NL80211_CMD_FRAME for backward compatibility.
649  * @NL80211_CMD_FRAME_TX_STATUS: Report TX status of a management frame
650  *	transmitted with %NL80211_CMD_FRAME. %NL80211_ATTR_COOKIE identifies
651  *	the TX command and %NL80211_ATTR_FRAME includes the contents of the
652  *	frame. %NL80211_ATTR_ACK flag is included if the recipient acknowledged
653  *	the frame.
654  * @NL80211_CMD_ACTION_TX_STATUS: Alias for @NL80211_CMD_FRAME_TX_STATUS for
655  *	backward compatibility.
656  *
657  * @NL80211_CMD_SET_POWER_SAVE: Set powersave, using %NL80211_ATTR_PS_STATE
658  * @NL80211_CMD_GET_POWER_SAVE: Get powersave status in %NL80211_ATTR_PS_STATE
659  *
660  * @NL80211_CMD_SET_CQM: Connection quality monitor configuration. This command
661  *	is used to configure connection quality monitoring notification trigger
662  *	levels.
663  * @NL80211_CMD_NOTIFY_CQM: Connection quality monitor notification. This
664  *	command is used as an event to indicate the that a trigger level was
665  *	reached.
666  * @NL80211_CMD_SET_CHANNEL: Set the channel (using %NL80211_ATTR_WIPHY_FREQ
667  *	and the attributes determining channel width) the given interface
668  *	(identifed by %NL80211_ATTR_IFINDEX) shall operate on.
669  *	In case multiple channels are supported by the device, the mechanism
670  *	with which it switches channels is implementation-defined.
671  *	When a monitor interface is given, it can only switch channel while
672  *	no other interfaces are operating to avoid disturbing the operation
673  *	of any other interfaces, and other interfaces will again take
674  *	precedence when they are used.
675  *
676  * @NL80211_CMD_SET_WDS_PEER: Set the MAC address of the peer on a WDS interface.
677  *
678  * @NL80211_CMD_SET_MULTICAST_TO_UNICAST: Configure if this AP should perform
679  *	multicast to unicast conversion. When enabled, all multicast packets
680  *	with ethertype ARP, IPv4 or IPv6 (possibly within an 802.1Q header)
681  *	will be sent out to each station once with the destination (multicast)
682  *	MAC address replaced by the station's MAC address. Note that this may
683  *	break certain expectations of the receiver, e.g. the ability to drop
684  *	unicast IP packets encapsulated in multicast L2 frames, or the ability
685  *	to not send destination unreachable messages in such cases.
686  *	This can only be toggled per BSS. Configure this on an interface of
687  *	type %NL80211_IFTYPE_AP. It applies to all its VLAN interfaces
688  *	(%NL80211_IFTYPE_AP_VLAN), except for those in 4addr (WDS) mode.
689  *	If %NL80211_ATTR_MULTICAST_TO_UNICAST_ENABLED is not present with this
690  *	command, the feature is disabled.
691  *
692  * @NL80211_CMD_JOIN_MESH: Join a mesh. The mesh ID must be given, and initial
693  *	mesh config parameters may be given.
694  * @NL80211_CMD_LEAVE_MESH: Leave the mesh network -- no special arguments, the
695  *	network is determined by the network interface.
696  *
697  * @NL80211_CMD_UNPROT_DEAUTHENTICATE: Unprotected deauthentication frame
698  *	notification. This event is used to indicate that an unprotected
699  *	deauthentication frame was dropped when MFP is in use.
700  * @NL80211_CMD_UNPROT_DISASSOCIATE: Unprotected disassociation frame
701  *	notification. This event is used to indicate that an unprotected
702  *	disassociation frame was dropped when MFP is in use.
703  *
704  * @NL80211_CMD_NEW_PEER_CANDIDATE: Notification on the reception of a
705  *      beacon or probe response from a compatible mesh peer.  This is only
706  *      sent while no station information (sta_info) exists for the new peer
707  *      candidate and when @NL80211_MESH_SETUP_USERSPACE_AUTH,
708  *      @NL80211_MESH_SETUP_USERSPACE_AMPE, or
709  *      @NL80211_MESH_SETUP_USERSPACE_MPM is set.  On reception of this
710  *      notification, userspace may decide to create a new station
711  *      (@NL80211_CMD_NEW_STATION).  To stop this notification from
712  *      reoccurring, the userspace authentication daemon may want to create the
713  *      new station with the AUTHENTICATED flag unset and maybe change it later
714  *      depending on the authentication result.
715  *
716  * @NL80211_CMD_GET_WOWLAN: get Wake-on-Wireless-LAN (WoWLAN) settings.
717  * @NL80211_CMD_SET_WOWLAN: set Wake-on-Wireless-LAN (WoWLAN) settings.
718  *	Since wireless is more complex than wired ethernet, it supports
719  *	various triggers. These triggers can be configured through this
720  *	command with the %NL80211_ATTR_WOWLAN_TRIGGERS attribute. For
721  *	more background information, see
722  *	http://wireless.kernel.org/en/users/Documentation/WoWLAN.
723  *	The @NL80211_CMD_SET_WOWLAN command can also be used as a notification
724  *	from the driver reporting the wakeup reason. In this case, the
725  *	@NL80211_ATTR_WOWLAN_TRIGGERS attribute will contain the reason
726  *	for the wakeup, if it was caused by wireless. If it is not present
727  *	in the wakeup notification, the wireless device didn't cause the
728  *	wakeup but reports that it was woken up.
729  *
730  * @NL80211_CMD_SET_REKEY_OFFLOAD: This command is used give the driver
731  *	the necessary information for supporting GTK rekey offload. This
732  *	feature is typically used during WoWLAN. The configuration data
733  *	is contained in %NL80211_ATTR_REKEY_DATA (which is nested and
734  *	contains the data in sub-attributes). After rekeying happened,
735  *	this command may also be sent by the driver as an MLME event to
736  *	inform userspace of the new replay counter.
737  *
738  * @NL80211_CMD_PMKSA_CANDIDATE: This is used as an event to inform userspace
739  *	of PMKSA caching dandidates.
740  *
741  * @NL80211_CMD_TDLS_OPER: Perform a high-level TDLS command (e.g. link setup).
742  *	In addition, this can be used as an event to request userspace to take
743  *	actions on TDLS links (set up a new link or tear down an existing one).
744  *	In such events, %NL80211_ATTR_TDLS_OPERATION indicates the requested
745  *	operation, %NL80211_ATTR_MAC contains the peer MAC address, and
746  *	%NL80211_ATTR_REASON_CODE the reason code to be used (only with
747  *	%NL80211_TDLS_TEARDOWN).
748  * @NL80211_CMD_TDLS_MGMT: Send a TDLS management frame. The
749  *	%NL80211_ATTR_TDLS_ACTION attribute determines the type of frame to be
750  *	sent. Public Action codes (802.11-2012 8.1.5.1) will be sent as
751  *	802.11 management frames, while TDLS action codes (802.11-2012
752  *	8.5.13.1) will be encapsulated and sent as data frames. The currently
753  *	supported Public Action code is %WLAN_PUB_ACTION_TDLS_DISCOVER_RES
754  *	and the currently supported TDLS actions codes are given in
755  *	&enum ieee80211_tdls_actioncode.
756  *
757  * @NL80211_CMD_UNEXPECTED_FRAME: Used by an application controlling an AP
758  *	(or GO) interface (i.e. hostapd) to ask for unexpected frames to
759  *	implement sending deauth to stations that send unexpected class 3
760  *	frames. Also used as the event sent by the kernel when such a frame
761  *	is received.
762  *	For the event, the %NL80211_ATTR_MAC attribute carries the TA and
763  *	other attributes like the interface index are present.
764  *	If used as the command it must have an interface index and you can
765  *	only unsubscribe from the event by closing the socket. Subscription
766  *	is also for %NL80211_CMD_UNEXPECTED_4ADDR_FRAME events.
767  *
768  * @NL80211_CMD_UNEXPECTED_4ADDR_FRAME: Sent as an event indicating that the
769  *	associated station identified by %NL80211_ATTR_MAC sent a 4addr frame
770  *	and wasn't already in a 4-addr VLAN. The event will be sent similarly
771  *	to the %NL80211_CMD_UNEXPECTED_FRAME event, to the same listener.
772  *
773  * @NL80211_CMD_PROBE_CLIENT: Probe an associated station on an AP interface
774  *	by sending a null data frame to it and reporting when the frame is
775  *	acknowleged. This is used to allow timing out inactive clients. Uses
776  *	%NL80211_ATTR_IFINDEX and %NL80211_ATTR_MAC. The command returns a
777  *	direct reply with an %NL80211_ATTR_COOKIE that is later used to match
778  *	up the event with the request. The event includes the same data and
779  *	has %NL80211_ATTR_ACK set if the frame was ACKed.
780  *
781  * @NL80211_CMD_REGISTER_BEACONS: Register this socket to receive beacons from
782  *	other BSSes when any interfaces are in AP mode. This helps implement
783  *	OLBC handling in hostapd. Beacons are reported in %NL80211_CMD_FRAME
784  *	messages. Note that per PHY only one application may register.
785  *
786  * @NL80211_CMD_SET_NOACK_MAP: sets a bitmap for the individual TIDs whether
787  *      No Acknowledgement Policy should be applied.
788  *
789  * @NL80211_CMD_CH_SWITCH_NOTIFY: An AP or GO may decide to switch channels
790  *	independently of the userspace SME, send this event indicating
791  *	%NL80211_ATTR_IFINDEX is now on %NL80211_ATTR_WIPHY_FREQ and the
792  *	attributes determining channel width.  This indication may also be
793  *	sent when a remotely-initiated switch (e.g., when a STA receives a CSA
794  *	from the remote AP) is completed;
795  *
796  * @NL80211_CMD_CH_SWITCH_STARTED_NOTIFY: Notify that a channel switch
797  *	has been started on an interface, regardless of the initiator
798  *	(ie. whether it was requested from a remote device or
799  *	initiated on our own).  It indicates that
800  *	%NL80211_ATTR_IFINDEX will be on %NL80211_ATTR_WIPHY_FREQ
801  *	after %NL80211_ATTR_CH_SWITCH_COUNT TBTT's.  The userspace may
802  *	decide to react to this indication by requesting other
803  *	interfaces to change channel as well.
804  *
805  * @NL80211_CMD_START_P2P_DEVICE: Start the given P2P Device, identified by
806  *	its %NL80211_ATTR_WDEV identifier. It must have been created with
807  *	%NL80211_CMD_NEW_INTERFACE previously. After it has been started, the
808  *	P2P Device can be used for P2P operations, e.g. remain-on-channel and
809  *	public action frame TX.
810  * @NL80211_CMD_STOP_P2P_DEVICE: Stop the given P2P Device, identified by
811  *	its %NL80211_ATTR_WDEV identifier.
812  *
813  * @NL80211_CMD_CONN_FAILED: connection request to an AP failed; used to
814  *	notify userspace that AP has rejected the connection request from a
815  *	station, due to particular reason. %NL80211_ATTR_CONN_FAILED_REASON
816  *	is used for this.
817  *
818  * @NL80211_CMD_SET_MCAST_RATE: Change the rate used to send multicast frames
819  *	for IBSS or MESH vif.
820  *
821  * @NL80211_CMD_SET_MAC_ACL: sets ACL for MAC address based access control.
822  *	This is to be used with the drivers advertising the support of MAC
823  *	address based access control. List of MAC addresses is passed in
824  *	%NL80211_ATTR_MAC_ADDRS and ACL policy is passed in
825  *	%NL80211_ATTR_ACL_POLICY. Driver will enable ACL with this list, if it
826  *	is not already done. The new list will replace any existing list. Driver
827  *	will clear its ACL when the list of MAC addresses passed is empty. This
828  *	command is used in AP/P2P GO mode. Driver has to make sure to clear its
829  *	ACL list during %NL80211_CMD_STOP_AP.
830  *
831  * @NL80211_CMD_RADAR_DETECT: Start a Channel availability check (CAC). Once
832  *	a radar is detected or the channel availability scan (CAC) has finished
833  *	or was aborted, or a radar was detected, usermode will be notified with
834  *	this event. This command is also used to notify userspace about radars
835  *	while operating on this channel.
836  *	%NL80211_ATTR_RADAR_EVENT is used to inform about the type of the
837  *	event.
838  *
839  * @NL80211_CMD_GET_PROTOCOL_FEATURES: Get global nl80211 protocol features,
840  *	i.e. features for the nl80211 protocol rather than device features.
841  *	Returns the features in the %NL80211_ATTR_PROTOCOL_FEATURES bitmap.
842  *
843  * @NL80211_CMD_UPDATE_FT_IES: Pass down the most up-to-date Fast Transition
844  *	Information Element to the WLAN driver
845  *
846  * @NL80211_CMD_FT_EVENT: Send a Fast transition event from the WLAN driver
847  *	to the supplicant. This will carry the target AP's MAC address along
848  *	with the relevant Information Elements. This event is used to report
849  *	received FT IEs (MDIE, FTIE, RSN IE, TIE, RICIE).
850  *
851  * @NL80211_CMD_CRIT_PROTOCOL_START: Indicates user-space will start running
852  *	a critical protocol that needs more reliability in the connection to
853  *	complete.
854  *
855  * @NL80211_CMD_CRIT_PROTOCOL_STOP: Indicates the connection reliability can
856  *	return back to normal.
857  *
858  * @NL80211_CMD_GET_COALESCE: Get currently supported coalesce rules.
859  * @NL80211_CMD_SET_COALESCE: Configure coalesce rules or clear existing rules.
860  *
861  * @NL80211_CMD_CHANNEL_SWITCH: Perform a channel switch by announcing the
862  *	the new channel information (Channel Switch Announcement - CSA)
863  *	in the beacon for some time (as defined in the
864  *	%NL80211_ATTR_CH_SWITCH_COUNT parameter) and then change to the
865  *	new channel. Userspace provides the new channel information (using
866  *	%NL80211_ATTR_WIPHY_FREQ and the attributes determining channel
867  *	width). %NL80211_ATTR_CH_SWITCH_BLOCK_TX may be supplied to inform
868  *	other station that transmission must be blocked until the channel
869  *	switch is complete.
870  *
871  * @NL80211_CMD_VENDOR: Vendor-specified command/event. The command is specified
872  *	by the %NL80211_ATTR_VENDOR_ID attribute and a sub-command in
873  *	%NL80211_ATTR_VENDOR_SUBCMD. Parameter(s) can be transported in
874  *	%NL80211_ATTR_VENDOR_DATA.
875  *	For feature advertisement, the %NL80211_ATTR_VENDOR_DATA attribute is
876  *	used in the wiphy data as a nested attribute containing descriptions
877  *	(&struct nl80211_vendor_cmd_info) of the supported vendor commands.
878  *	This may also be sent as an event with the same attributes.
879  *
880  * @NL80211_CMD_SET_QOS_MAP: Set Interworking QoS mapping for IP DSCP values.
881  *	The QoS mapping information is included in %NL80211_ATTR_QOS_MAP. If
882  *	that attribute is not included, QoS mapping is disabled. Since this
883  *	QoS mapping is relevant for IP packets, it is only valid during an
884  *	association. This is cleared on disassociation and AP restart.
885  *
886  * @NL80211_CMD_ADD_TX_TS: Ask the kernel to add a traffic stream for the given
887  *	%NL80211_ATTR_TSID and %NL80211_ATTR_MAC with %NL80211_ATTR_USER_PRIO
888  *	and %NL80211_ATTR_ADMITTED_TIME parameters.
889  *	Note that the action frame handshake with the AP shall be handled by
890  *	userspace via the normal management RX/TX framework, this only sets
891  *	up the TX TS in the driver/device.
892  *	If the admitted time attribute is not added then the request just checks
893  *	if a subsequent setup could be successful, the intent is to use this to
894  *	avoid setting up a session with the AP when local restrictions would
895  *	make that impossible. However, the subsequent "real" setup may still
896  *	fail even if the check was successful.
897  * @NL80211_CMD_DEL_TX_TS: Remove an existing TS with the %NL80211_ATTR_TSID
898  *	and %NL80211_ATTR_MAC parameters. It isn't necessary to call this
899  *	before removing a station entry entirely, or before disassociating
900  *	or similar, cleanup will happen in the driver/device in this case.
901  *
902  * @NL80211_CMD_GET_MPP: Get mesh path attributes for mesh proxy path to
903  *	destination %NL80211_ATTR_MAC on the interface identified by
904  *	%NL80211_ATTR_IFINDEX.
905  *
906  * @NL80211_CMD_JOIN_OCB: Join the OCB network. The center frequency and
907  *	bandwidth of a channel must be given.
908  * @NL80211_CMD_LEAVE_OCB: Leave the OCB network -- no special arguments, the
909  *	network is determined by the network interface.
910  *
911  * @NL80211_CMD_TDLS_CHANNEL_SWITCH: Start channel-switching with a TDLS peer,
912  *	identified by the %NL80211_ATTR_MAC parameter. A target channel is
913  *	provided via %NL80211_ATTR_WIPHY_FREQ and other attributes determining
914  *	channel width/type. The target operating class is given via
915  *	%NL80211_ATTR_OPER_CLASS.
916  *	The driver is responsible for continually initiating channel-switching
917  *	operations and returning to the base channel for communication with the
918  *	AP.
919  * @NL80211_CMD_TDLS_CANCEL_CHANNEL_SWITCH: Stop channel-switching with a TDLS
920  *	peer given by %NL80211_ATTR_MAC. Both peers must be on the base channel
921  *	when this command completes.
922  *
923  * @NL80211_CMD_WIPHY_REG_CHANGE: Similar to %NL80211_CMD_REG_CHANGE, but used
924  *	as an event to indicate changes for devices with wiphy-specific regdom
925  *	management.
926  *
927  * @NL80211_CMD_ABORT_SCAN: Stop an ongoing scan. Returns -ENOENT if a scan is
928  *	not running. The driver indicates the status of the scan through
929  *	cfg80211_scan_done().
930  *
931  * @NL80211_CMD_START_NAN: Start NAN operation, identified by its
932  *	%NL80211_ATTR_WDEV interface. This interface must have been
933  *	previously created with %NL80211_CMD_NEW_INTERFACE. After it
934  *	has been started, the NAN interface will create or join a
935  *	cluster. This command must have a valid
936  *	%NL80211_ATTR_NAN_MASTER_PREF attribute and optional
937  *	%NL80211_ATTR_BANDS attributes.  If %NL80211_ATTR_BANDS is
938  *	omitted or set to 0, it means don't-care and the device will
939  *	decide what to use.  After this command NAN functions can be
940  *	added.
941  * @NL80211_CMD_STOP_NAN: Stop the NAN operation, identified by
942  *	its %NL80211_ATTR_WDEV interface.
943  * @NL80211_CMD_ADD_NAN_FUNCTION: Add a NAN function. The function is defined
944  *	with %NL80211_ATTR_NAN_FUNC nested attribute. When called, this
945  *	operation returns the strictly positive and unique instance id
946  *	(%NL80211_ATTR_NAN_FUNC_INST_ID) and a cookie (%NL80211_ATTR_COOKIE)
947  *	of the function upon success.
948  *	Since instance ID's can be re-used, this cookie is the right
949  *	way to identify the function. This will avoid races when a termination
950  *	event is handled by the user space after it has already added a new
951  *	function that got the same instance id from the kernel as the one
952  *	which just terminated.
953  *	This cookie may be used in NAN events even before the command
954  *	returns, so userspace shouldn't process NAN events until it processes
955  *	the response to this command.
956  *	Look at %NL80211_ATTR_SOCKET_OWNER as well.
957  * @NL80211_CMD_DEL_NAN_FUNCTION: Delete a NAN function by cookie.
958  *	This command is also used as a notification sent when a NAN function is
959  *	terminated. This will contain a %NL80211_ATTR_NAN_FUNC_INST_ID
960  *	and %NL80211_ATTR_COOKIE attributes.
961  * @NL80211_CMD_CHANGE_NAN_CONFIG: Change current NAN
962  *	configuration. NAN must be operational (%NL80211_CMD_START_NAN
963  *	was executed).  It must contain at least one of the following
964  *	attributes: %NL80211_ATTR_NAN_MASTER_PREF,
965  *	%NL80211_ATTR_BANDS.  If %NL80211_ATTR_BANDS is omitted, the
966  *	current configuration is not changed.  If it is present but
967  *	set to zero, the configuration is changed to don't-care
968  *	(i.e. the device can decide what to do).
969  * @NL80211_CMD_NAN_FUNC_MATCH: Notification sent when a match is reported.
970  *	This will contain a %NL80211_ATTR_NAN_MATCH nested attribute and
971  *	%NL80211_ATTR_COOKIE.
972  *
973  * @NL80211_CMD_UPDATE_CONNECT_PARAMS: Update one or more connect parameters
974  *	for subsequent roaming cases if the driver or firmware uses internal
975  *	BSS selection. This command can be issued only while connected and it
976  *	does not result in a change for the current association. Currently,
977  *	only the %NL80211_ATTR_IE data is used and updated with this command.
978  *
979  * @NL80211_CMD_SET_PMK: For offloaded 4-Way handshake, set the PMK or PMK-R0
980  *	for the given authenticator address (specified with &NL80211_ATTR_MAC).
981  *	When &NL80211_ATTR_PMKR0_NAME is set, &NL80211_ATTR_PMK specifies the
982  *	PMK-R0, otherwise it specifies the PMK.
983  * @NL80211_CMD_DEL_PMK: For offloaded 4-Way handshake, delete the previously
984  *	configured PMK for the authenticator address identified by
985  *	&NL80211_ATTR_MAC.
986  * @NL80211_CMD_PORT_AUTHORIZED: An event that indicates that the 4 way
987  *	handshake was completed successfully by the driver. The BSSID is
988  *	specified with &NL80211_ATTR_MAC. Drivers that support 4 way handshake
989  *	offload should send this event after indicating 802.11 association with
990  *	&NL80211_CMD_CONNECT or &NL80211_CMD_ROAM. If the 4 way handshake failed
991  *	&NL80211_CMD_DISCONNECT should be indicated instead.
992  *
993  * @NL80211_CMD_RELOAD_REGDB: Request that the regdb firmware file is reloaded.
994  *
995  * @NL80211_CMD_MAX: highest used command number
996  * @__NL80211_CMD_AFTER_LAST: internal use

1613  *	containing attributes from &enum nl80211_meshconf_params.
1614  * @NL80211_ATTR_SUPPORT_MESH_AUTH: Currently, this means the underlying driver
1615  *	allows auth frames in a mesh to be passed to userspace for processing via

1633  *	sets of attributes to match during scheduled scans.  Only BSSs
1634  *	that match any of the sets will be reported.  These are
1635  *	pass-thru filter rules.
1636  *	For a match to succeed, the BSS must match all attributes of a
1637  *	set.  Since not every hardware supports matching all types of
1638  *	attributes, there is no guarantee that the reported BSSs are
1639  *	fully complying with the match sets and userspace needs to be
1640  *	able to ignore them by itself.
1641  *	Thus, the implementation is somewhat hardware-dependent, but
1642  *	this is only an optimization and the userspace application
1643  *	needs to handle all the non-filtered results anyway.
1644  *	If the match attributes don't make sense when combined with
1645  *	the values passed in @NL80211_ATTR_SCAN_SSIDS (eg. if an SSID
1646  *	is included in the probe request, but the match attributes

1674  * @NL80211_ATTR_IE_ASSOC_RESP: Information element(s) for (Re)Association
1675  *	Response frames. This is used with %NL80211_CMD_NEW_BEACON and

1692  *	for management frames transmission. In order to avoid p2p probe/action
1693  *	frames are being transmitted at CCK rate in 2GHz band, the user space
1694  *	applications use this attribute.
1695  *	This attribute is used with %NL80211_CMD_TRIGGER_SCAN and

1716  *
1717  * @NL80211_ATTR_DONT_WAIT_FOR_ACK: Used with %NL80211_CMD_FRAME, this tells
1718  *	the driver to not wait for an acknowledgement. Note that due to this,
1719  *	it will also not give a status callback nor return a cookie. This is

4356  * DOC: TCP connection wakeup
4357  *
4358  * Some devices can establish a TCP connection in order to be woken up by a
4359  * packet coming in from outside their network segment, or behind NAT. If
4360  * configured, the device will establish a TCP connection to the given
4361  * service, and periodically send data to that service. The first data
4362  * packet is usually transmitted after SYN/ACK, also ACKing the SYN/ACK.
4363  * The data packets can optionally include a (little endian) sequence
4364  * number (in the TCP payload!) that is generated by the device, and, also
4365  * optionally, a token from a list of tokens. This serves as a keep-alive
4366  * with the service, and for NATed connections, etc.
4367  *
4368  * During this keep-alive period, the server doesn't send any data to the
4369  * client. When receiving data, it is compared against the wakeup pattern
4370  * (and mask) and if it matches, the host is woken up. Similarly, if the
4371  * connection breaks or cannot be established to start with, the host is
4372  * also woken up.
4373  *
4374  * Developer's note: ARP offload is required for this, otherwise TCP
4375  * response packets might not go through correctly.

4762  * @NL80211_FEATURE_CELL_BASE_REG_HINTS: This driver has been tested
4763  *	to work properly to suppport receiving regulatory hints from
4764  *	cellular base stations.
4765  * @NL80211_FEATURE_P2P_DEVICE_NEEDS_CHANNEL: (no longer available, only
4766  *	here to reserve the value for API/ABI compatibility)
