     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)

     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.

     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.

    131  * In most cases, host that receives IPv4 and IPv6 multicast/broadcast
    132  * packets does not do anything with these packets. Therefore the

    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_ATTR_CSA_C_OFFSETS_TX is an array of offsets to CSA
    507  *	counters which will be updated to the current value. This attribute
    508  *	is used during CSA period.
    509  * @NL80211_CMD_FRAME_WAIT_CANCEL: When an off-channel TX was requested, this
    510  *	command may be used with the corresponding cookie to cancel the wait
    511  *	time if it is known that it is no longer necessary.
    512  * @NL80211_CMD_ACTION: Alias for @NL80211_CMD_FRAME for backward compatibility.
    513  * @NL80211_CMD_FRAME_TX_STATUS: Report TX status of a management frame
    514  *	transmitted with %NL80211_CMD_FRAME. %NL80211_ATTR_COOKIE identifies
    515  *	the TX command and %NL80211_ATTR_FRAME includes the contents of the
    516  *	frame. %NL80211_ATTR_ACK flag is included if the recipient acknowledged
    517  *	the frame.
    518  * @NL80211_CMD_ACTION_TX_STATUS: Alias for @NL80211_CMD_FRAME_TX_STATUS for
    519  *	backward compatibility.
    520  *
    521  * @NL80211_CMD_SET_POWER_SAVE: Set powersave, using %NL80211_ATTR_PS_STATE
    522  * @NL80211_CMD_GET_POWER_SAVE: Get powersave status in %NL80211_ATTR_PS_STATE
    523  *
    524  * @NL80211_CMD_SET_CQM: Connection quality monitor configuration. This command
    525  *	is used to configure connection quality monitoring notification trigger
    526  *	levels.
    527  * @NL80211_CMD_NOTIFY_CQM: Connection quality monitor notification. This
    528  *	command is used as an event to indicate the that a trigger level was
    529  *	reached.
    530  * @NL80211_CMD_SET_CHANNEL: Set the channel (using %NL80211_ATTR_WIPHY_FREQ
    531  *	and the attributes determining channel width) the given interface
    532  *	(identifed by %NL80211_ATTR_IFINDEX) shall operate on.
    533  *	In case multiple channels are supported by the device, the mechanism
    534  *	with which it switches channels is implementation-defined.
    535  *	When a monitor interface is given, it can only switch channel while
    536  *	no other interfaces are operating to avoid disturbing the operation
    537  *	of any other interfaces, and other interfaces will again take
    538  *	precedence when they are used.
    539  *
    540  * @NL80211_CMD_SET_WDS_PEER: Set the MAC address of the peer on a WDS interface.
    541  *
    542  * @NL80211_CMD_JOIN_MESH: Join a mesh. The mesh ID must be given, and initial
    543  *	mesh config parameters may be given.
    544  * @NL80211_CMD_LEAVE_MESH: Leave the mesh network -- no special arguments, the
    545  *	network is determined by the network interface.
    546  *
    547  * @NL80211_CMD_UNPROT_DEAUTHENTICATE: Unprotected deauthentication frame
    548  *	notification. This event is used to indicate that an unprotected
    549  *	deauthentication frame was dropped when MFP is in use.
    550  * @NL80211_CMD_UNPROT_DISASSOCIATE: Unprotected disassociation frame
    551  *	notification. This event is used to indicate that an unprotected
    552  *	disassociation frame was dropped when MFP is in use.
    553  *
    554  * @NL80211_CMD_NEW_PEER_CANDIDATE: Notification on the reception of a
    555  *      beacon or probe response from a compatible mesh peer.  This is only
    556  *      sent while no station information (sta_info) exists for the new peer
    557  *      candidate and when @NL80211_MESH_SETUP_USERSPACE_AUTH,
    558  *      @NL80211_MESH_SETUP_USERSPACE_AMPE, or
    559  *      @NL80211_MESH_SETUP_USERSPACE_MPM is set.  On reception of this
    560  *      notification, userspace may decide to create a new station
    561  *      (@NL80211_CMD_NEW_STATION).  To stop this notification from
    562  *      reoccurring, the userspace authentication daemon may want to create the
    563  *      new station with the AUTHENTICATED flag unset and maybe change it later
    564  *      depending on the authentication result.
    565  *
    566  * @NL80211_CMD_GET_WOWLAN: get Wake-on-Wireless-LAN (WoWLAN) settings.
    567  * @NL80211_CMD_SET_WOWLAN: set Wake-on-Wireless-LAN (WoWLAN) settings.
    568  *	Since wireless is more complex than wired ethernet, it supports
    569  *	various triggers. These triggers can be configured through this
    570  *	command with the %NL80211_ATTR_WOWLAN_TRIGGERS attribute. For
    571  *	more background information, see
    572  *	http://wireless.kernel.org/en/users/Documentation/WoWLAN.
    573  *	The @NL80211_CMD_SET_WOWLAN command can also be used as a notification
    574  *	from the driver reporting the wakeup reason. In this case, the
    575  *	@NL80211_ATTR_WOWLAN_TRIGGERS attribute will contain the reason
    576  *	for the wakeup, if it was caused by wireless. If it is not present
    577  *	in the wakeup notification, the wireless device didn't cause the
    578  *	wakeup but reports that it was woken up.
    579  *
    580  * @NL80211_CMD_SET_REKEY_OFFLOAD: This command is used give the driver
    581  *	the necessary information for supporting GTK rekey offload. This
    582  *	feature is typically used during WoWLAN. The configuration data
    583  *	is contained in %NL80211_ATTR_REKEY_DATA (which is nested and
    584  *	contains the data in sub-attributes). After rekeying happened,
    585  *	this command may also be sent by the driver as an MLME event to
    586  *	inform userspace of the new replay counter.
    587  *
    588  * @NL80211_CMD_PMKSA_CANDIDATE: This is used as an event to inform userspace
    589  *	of PMKSA caching dandidates.
    590  *
    591  * @NL80211_CMD_TDLS_OPER: Perform a high-level TDLS command (e.g. link setup).
    592  *	In addition, this can be used as an event to request userspace to take
    593  *	actions on TDLS links (set up a new link or tear down an existing one).
    594  *	In such events, %NL80211_ATTR_TDLS_OPERATION indicates the requested
    595  *	operation, %NL80211_ATTR_MAC contains the peer MAC address, and
    596  *	%NL80211_ATTR_REASON_CODE the reason code to be used (only with
    597  *	%NL80211_TDLS_TEARDOWN).
    598  * @NL80211_CMD_TDLS_MGMT: Send a TDLS management frame. The
    599  *	%NL80211_ATTR_TDLS_ACTION attribute determines the type of frame to be
    600  *	sent. Public Action codes (802.11-2012 8.1.5.1) will be sent as
    601  *	802.11 management frames, while TDLS action codes (802.11-2012
    602  *	8.5.13.1) will be encapsulated and sent as data frames. The currently

    604  *	and the currently supported TDLS actions codes are given in
    605  *	&enum ieee80211_tdls_actioncode.
    606  *
    607  * @NL80211_CMD_UNEXPECTED_FRAME: Used by an application controlling an AP
    608  *	(or GO) interface (i.e. hostapd) to ask for unexpected frames to
    609  *	implement sending deauth to stations that send unexpected class 3
    610  *	frames. Also used as the event sent by the kernel when such a frame
    611  *	is received.
    612  *	For the event, the %NL80211_ATTR_MAC attribute carries the TA and
    613  *	other attributes like the interface index are present.
    614  *	If used as the command it must have an interface index and you can
    615  *	only unsubscribe from the event by closing the socket. Subscription
    616  *	is also for %NL80211_CMD_UNEXPECTED_4ADDR_FRAME events.
    617  *
    618  * @NL80211_CMD_UNEXPECTED_4ADDR_FRAME: Sent as an event indicating that the
    619  *	associated station identified by %NL80211_ATTR_MAC sent a 4addr frame
    620  *	and wasn't already in a 4-addr VLAN. The event will be sent similarly
    621  *	to the %NL80211_CMD_UNEXPECTED_FRAME event, to the same listener.
    622  *
    623  * @NL80211_CMD_PROBE_CLIENT: Probe an associated station on an AP interface
    624  *	by sending a null data frame to it and reporting when the frame is
    625  *	acknowleged. This is used to allow timing out inactive clients. Uses
    626  *	%NL80211_ATTR_IFINDEX and %NL80211_ATTR_MAC. The command returns a
    627  *	direct reply with an %NL80211_ATTR_COOKIE that is later used to match
    628  *	up the event with the request. The event includes the same data and
    629  *	has %NL80211_ATTR_ACK set if the frame was ACKed.
    630  *
    631  * @NL80211_CMD_REGISTER_BEACONS: Register this socket to receive beacons from
    632  *	other BSSes when any interfaces are in AP mode. This helps implement
    633  *	OLBC handling in hostapd. Beacons are reported in %NL80211_CMD_FRAME
    634  *	messages. Note that per PHY only one application may register.
    635  *
    636  * @NL80211_CMD_SET_NOACK_MAP: sets a bitmap for the individual TIDs whether
    637  *      No Acknowledgement Policy should be applied.
    638  *
    639  * @NL80211_CMD_CH_SWITCH_NOTIFY: An AP or GO may decide to switch channels
    640  *	independently of the userspace SME, send this event indicating
    641  *	%NL80211_ATTR_IFINDEX is now on %NL80211_ATTR_WIPHY_FREQ and the
    642  *	attributes determining channel width.
    643  *
    644  * @NL80211_CMD_START_P2P_DEVICE: Start the given P2P Device, identified by
    645  *	its %NL80211_ATTR_WDEV identifier. It must have been created with
    646  *	%NL80211_CMD_NEW_INTERFACE previously. After it has been started, the
    647  *	P2P Device can be used for P2P operations, e.g. remain-on-channel and
    648  *	public action frame TX.
    649  * @NL80211_CMD_STOP_P2P_DEVICE: Stop the given P2P Device, identified by
    650  *	its %NL80211_ATTR_WDEV identifier.
    651  *
    652  * @NL80211_CMD_CONN_FAILED: connection request to an AP failed; used to
    653  *	notify userspace that AP has rejected the connection request from a
    654  *	station, due to particular reason. %NL80211_ATTR_CONN_FAILED_REASON
    655  *	is used for this.
    656  *
    657  * @NL80211_CMD_SET_MCAST_RATE: Change the rate used to send multicast frames
    658  *	for IBSS or MESH vif.
    659  *
    660  * @NL80211_CMD_SET_MAC_ACL: sets ACL for MAC address based access control.
    661  *	This is to be used with the drivers advertising the support of MAC
    662  *	address based access control. List of MAC addresses is passed in
    663  *	%NL80211_ATTR_MAC_ADDRS and ACL policy is passed in
    664  *	%NL80211_ATTR_ACL_POLICY. Driver will enable ACL with this list, if it
    665  *	is not already done. The new list will replace any existing list. Driver
    666  *	will clear its ACL when the list of MAC addresses passed is empty. This
    667  *	command is used in AP/P2P GO mode. Driver has to make sure to clear its
    668  *	ACL list during %NL80211_CMD_STOP_AP.
    669  *
    670  * @NL80211_CMD_RADAR_DETECT: Start a Channel availability check (CAC). Once
    671  *	a radar is detected or the channel availability scan (CAC) has finished
    672  *	or was aborted, or a radar was detected, usermode will be notified with
    673  *	this event. This command is also used to notify userspace about radars
    674  *	while operating on this channel.
    675  *	%NL80211_ATTR_RADAR_EVENT is used to inform about the type of the
    676  *	event.
    677  *
    678  * @NL80211_CMD_GET_PROTOCOL_FEATURES: Get global nl80211 protocol features,
    679  *	i.e. features for the nl80211 protocol rather than device features.
    680  *	Returns the features in the %NL80211_ATTR_PROTOCOL_FEATURES bitmap.
    681  *
    682  * @NL80211_CMD_UPDATE_FT_IES: Pass down the most up-to-date Fast Transition
    683  *	Information Element to the WLAN driver
    684  *
    685  * @NL80211_CMD_FT_EVENT: Send a Fast transition event from the WLAN driver
    686  *	to the supplicant. This will carry the target AP's MAC address along
    687  *	with the relevant Information Elements. This event is used to report
    688  *	received FT IEs (MDIE, FTIE, RSN IE, TIE, RICIE).
    689  *
    690  * @NL80211_CMD_CRIT_PROTOCOL_START: Indicates user-space will start running
    691  *	a critical protocol that needs more reliability in the connection to
    692  *	complete.
    693  *
    694  * @NL80211_CMD_CRIT_PROTOCOL_STOP: Indicates the connection reliability can
    695  *	return back to normal.
    696  *
    697  * @NL80211_CMD_GET_COALESCE: Get currently supported coalesce rules.
    698  * @NL80211_CMD_SET_COALESCE: Configure coalesce rules or clear existing rules.
    699  *
    700  * @NL80211_CMD_CHANNEL_SWITCH: Perform a channel switch by announcing the
    701  *	the new channel information (Channel Switch Announcement - CSA)
    702  *	in the beacon for some time (as defined in the
    703  *	%NL80211_ATTR_CH_SWITCH_COUNT parameter) and then change to the
    704  *	new channel. Userspace provides the new channel information (using
    705  *	%NL80211_ATTR_WIPHY_FREQ and the attributes determining channel
    706  *	width). %NL80211_ATTR_CH_SWITCH_BLOCK_TX may be supplied to inform
    707  *	other station that transmission must be blocked until the channel
    708  *	switch is complete.
    709  *
    710  * @NL80211_CMD_VENDOR: Vendor-specified command/event. The command is specified
    711  *	by the %NL80211_ATTR_VENDOR_ID attribute and a sub-command in
    712  *	%NL80211_ATTR_VENDOR_SUBCMD. Parameter(s) can be transported in
    713  *	%NL80211_ATTR_VENDOR_DATA.
    714  *	For feature advertisement, the %NL80211_ATTR_VENDOR_DATA attribute is
    715  *	used in the wiphy data as a nested attribute containing descriptions
    716  *	(&struct nl80211_vendor_cmd_info) of the supported vendor commands.
    717  *	This may also be sent as an event with the same attributes.
    718  *
    719  * @NL80211_CMD_SET_QOS_MAP: Set Interworking QoS mapping for IP DSCP values.
    720  *	The QoS mapping information is included in %NL80211_ATTR_QOS_MAP. If
    721  *	that attribute is not included, QoS mapping is disabled. Since this
    722  *	QoS mapping is relevant for IP packets, it is only valid during an
    723  *	association. This is cleared on disassociation and AP restart.
    724  *
    725  * @NL80211_CMD_ADD_TX_TS: Ask the kernel to add a traffic stream for the given
    726  *	%NL80211_ATTR_TSID and %NL80211_ATTR_MAC with %NL80211_ATTR_USER_PRIO
    727  *	and %NL80211_ATTR_ADMITTED_TIME parameters.
    728  *	Note that the action frame handshake with the AP shall be handled by
    729  *	userspace via the normal management RX/TX framework, this only sets
    730  *	up the TX TS in the driver/device.
    731  *	If the admitted time attribute is not added then the request just checks
    732  *	if a subsequent setup could be successful, the intent is to use this to
    733  *	avoid setting up a session with the AP when local restrictions would
    734  *	make that impossible. However, the subsequent "real" setup may still
    735  *	fail even if the check was successful.
    736  * @NL80211_CMD_DEL_TX_TS: Remove an existing TS with the %NL80211_ATTR_TSID
    737  *	and %NL80211_ATTR_MAC parameters. It isn't necessary to call this
    738  *	before removing a station entry entirely, or before disassociating
    739  *	or similar, cleanup will happen in the driver/device in this case.
    740  *
    741  * @NL80211_CMD_MAX: highest used command number
    742  * @__NL80211_CMD_AFTER_LAST: internal use

   1314  *	containing attributes from &enum nl80211_meshconf_params.
   1315  * @NL80211_ATTR_SUPPORT_MESH_AUTH: Currently, this means the underlying driver
   1316  *	allows auth frames in a mesh to be passed to userspace for processing via
   1317  *	the @NL80211_MESH_SETUP_USERSPACE_AUTH flag.
   1318  * @NL80211_ATTR_STA_PLINK_STATE: The state of a mesh peer link as defined in

   1336  *	pass-thru filter rules.
   1337  *	For a match to succeed, the BSS must match all attributes of a
   1338  *	set.  Since not every hardware supports matching all types of
   1339  *	attributes, there is no guarantee that the reported BSSs are
   1340  *	fully complying with the match sets and userspace needs to be
   1341  *	able to ignore them by itself.
   1342  *	Thus, the implementation is somewhat hardware-dependent, but
   1343  *	this is only an optimization and the userspace application
   1344  *	needs to handle all the non-filtered results anyway.
   1345  *	If the match attributes don't make sense when combined with
   1346  *	the values passed in @NL80211_ATTR_SCAN_SSIDS (eg. if an SSID
   1347  *	is included in the probe request, but the match attributes
   1348  *	will never let it go through), -EINVAL may be returned.

   1617  *	shall support Radio Resource Measurements (11k). This attribute can be
   1618  *	used with %NL80211_CMD_ASSOCIATE and %NL80211_CMD_CONNECT requests.
   1619  *	User space applications are expected to use this flag only if the
   1620  *	underlying device supports these minimal RRM features:
   1621  *		%NL80211_FEATURE_DS_PARAM_SET_IE_IN_PROBES,
   1622  *		%NL80211_FEATURE_QUIET,
   1623  *	If this flag is used, driver must add the Power Capabilities IE to the
   1624  *	association request. In addition, it must also set the RRM capability
   1625  *	flag in the association request's Capability Info field.
   1626  *
   1627  * @NL80211_ATTR_WIPHY_DYN_ACK: flag attribute used to enable ACK timeout
   1628  *	estimation algorithm (dynack). In order to activate dynack
   1629  *	%NL80211_FEATURE_ACKTO_ESTIMATION feature flag must be set by lower
   1630  *	drivers to indicate dynack capability. Dynack is automatically disabled
   1631  *	setting valid value for coverage class.
   1632  *
   1633  * @NL80211_ATTR_TSID: a TSID value (u8 attribute)

   3580  * DOC: TCP connection wakeup
   3581  *
   3582  * Some devices can establish a TCP connection in order to be woken up by a
   3583  * packet coming in from outside their network segment, or behind NAT. If
   3584  * configured, the device will establish a TCP connection to the given
   3585  * service, and periodically send data to that service. The first data
   3586  * packet is usually transmitted after SYN/ACK, also ACKing the SYN/ACK.
   3587  * The data packets can optionally include a (little endian) sequence
   3588  * number (in the TCP payload!) that is generated by the device, and, also
   3589  * optionally, a token from a list of tokens. This serves as a keep-alive
   3590  * with the service, and for NATed connections, etc.
   3591  *
   3592  * During this keep-alive period, the server doesn't send any data to the

   4016  *	beacons or NL80211_CMD_NEW_PEER_CANDIDATE events. The mesh beacon is
   4017  *	still generated by the driver.
   4018  * @NL80211_FEATURE_ACTIVE_MONITOR: This driver supports an active monitor
   4019  *	interface. An active monitor interface behaves like a normal monitor
   4020  *	interface, but gets added to the driver. It ensures that incoming
   4021  *	unicast packets directed at the configured interface address get ACKed.
