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

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

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

   *
   * @NL80211_CMD_GET_MESH_CONFIG: Get mesh networking properties for the

   *	added to the end of the specified management frame is specified with
   *	%NL80211_ATTR_IE. If the command succeeds, the requested data will be
   *	added to all specified management frames generated by
   *	kernel/firmware/driver.
   *	Note: This command has been removed and it is only reserved at this
   *	point to avoid re-using existing command number. The functionality this
   *	command was planned for has been provided with cleaner design with the
   *	option to specify additional IEs in NL80211_CMD_TRIGGER_SCAN,
   *	NL80211_CMD_AUTHENTICATE, NL80211_CMD_ASSOCIATE,
   *	NL80211_CMD_DEAUTHENTICATE, and NL80211_CMD_DISASSOCIATE.
   *
   * @NL80211_CMD_GET_SCAN: get scan results
   * @NL80211_CMD_TRIGGER_SCAN: trigger a new scan with the given parameters
   *	%NL80211_ATTR_TX_NO_CCK_RATE is used to decide whether to send the
   *	probe requests at CCK rate or not.
   * @NL80211_CMD_NEW_SCAN_RESULTS: scan notification (as a reply to
   *	NL80211_CMD_GET_SCAN and on the "scan" multicast group)
   * @NL80211_CMD_SCAN_ABORTED: scan was aborted, for unspecified reasons,
   *	partial scan results may be available
   *
   * @NL80211_CMD_START_SCHED_SCAN: start a scheduled scan at certain
   *	intervals, as specified by %NL80211_ATTR_SCHED_SCAN_INTERVAL.
   *	Like with normal scans, if SSIDs (%NL80211_ATTR_SCAN_SSIDS)
   *	are passed, they are used in the probe requests.  For
   *	broadcast, a broadcast SSID must be passed (ie. an empty
   *	string).  If no SSID is passed, no probe requests are sent and
   *	a passive scan is performed.  %NL80211_ATTR_SCAN_FREQUENCIES,
   *	if passed, define which channels should be scanned; if not
   *	passed, all channels allowed for the current regulatory domain
   *	are used.  Extra IEs can also be passed from the userspace by
   *	using the %NL80211_ATTR_IE attribute.
   * @NL80211_CMD_STOP_SCHED_SCAN: stop a scheduled scan.  Returns -ENOENT
   *	if scheduled scan is not running.
   * @NL80211_CMD_SCHED_SCAN_RESULTS: indicates that there are scheduled scan
   *	results available.
   * @NL80211_CMD_SCHED_SCAN_STOPPED: indicates that the scheduled scan has
   *	stopped.  The driver may issue this event at any time during a
   *	scheduled scan.  One reason for stopping the scan is if the hardware
   *	does not support starting an association or a normal scan while running
   *	a scheduled scan.  This event is also sent when the
   *	%NL80211_CMD_STOP_SCHED_SCAN command is received or when the interface
   *	is brought down while a scheduled scan was running.
   *
   * @NL80211_CMD_GET_SURVEY: get survey resuls, e.g. channel occupation
   *      or noise level
   * @NL80211_CMD_NEW_SURVEY_RESULTS: survey data notification (as a reply to
   *	NL80211_CMD_GET_SURVEY and on the "scan" multicast group)
   *
   * @NL80211_CMD_SET_PMKSA: Add a PMKSA cache entry, using %NL80211_ATTR_MAC
   *	(for the BSSID) and %NL80211_ATTR_PMKID.
   * @NL80211_CMD_DEL_PMKSA: Delete a PMKSA cache entry, using %NL80211_ATTR_MAC
   *	(for the BSSID) and %NL80211_ATTR_PMKID.
   * @NL80211_CMD_FLUSH_PMKSA: Flush all PMKSA cache entries.
   *
   * @NL80211_CMD_REG_CHANGE: indicates to userspace the regulatory domain
   * 	has been changed and provides details of the request information
   * 	that caused the change such as who initiated the regulatory request
   * 	(%NL80211_ATTR_REG_INITIATOR), the wiphy_idx
   * 	(%NL80211_ATTR_REG_ALPHA2) on which the request was made from if
   * 	the initiator was %NL80211_REGDOM_SET_BY_COUNTRY_IE or
   * 	%NL80211_REGDOM_SET_BY_DRIVER, the type of regulatory domain
   * 	set (%NL80211_ATTR_REG_TYPE), if the type of regulatory domain is
   * 	%NL80211_REG_TYPE_COUNTRY the alpha2 to which we have moved on
   * 	to (%NL80211_ATTR_REG_ALPHA2).
   * @NL80211_CMD_REG_BEACON_HINT: indicates to userspace that an AP beacon
   * 	has been found while world roaming thus enabling active scan or
   * 	any mode of operation that initiates TX (beacons) on a channel
   * 	where we would not have been able to do either before. As an example
   * 	if you are world roaming (regulatory domain set to world or if your
   * 	driver is using a custom world roaming regulatory domain) and while
   * 	doing a passive scan on the 5 GHz band you find an AP there (if not
   * 	on a DFS channel) you will now be able to actively scan for that AP
   * 	or use AP mode on your card on that same channel. Note that this will
   * 	never be used for channels 1-11 on the 2 GHz band as they are always
   * 	enabled world wide. This beacon hint is only sent if your device had
   * 	either disabled active scanning or beaconing on a channel. We send to
   * 	userspace the wiphy on which we removed a restriction from
   * 	(%NL80211_ATTR_WIPHY) and the channel on which this occurred
   * 	before (%NL80211_ATTR_FREQ_BEFORE) and after (%NL80211_ATTR_FREQ_AFTER)
   * 	the beacon hint was processed.
   *
   * @NL80211_CMD_AUTHENTICATE: authentication request and notification.
   *	This command is used both as a command (request to authenticate) and
   *	as an event on the "mlme" multicast group indicating completion of the
   *	authentication process.
   *	When used as a command, %NL80211_ATTR_IFINDEX is used to identify the
   *	interface. %NL80211_ATTR_MAC is used to specify PeerSTAAddress (and
   *	BSSID in case of station mode). %NL80211_ATTR_SSID is used to specify
   *	the SSID (mainly for association, but is included in authentication
   *	request, too, to help BSS selection. %NL80211_ATTR_WIPHY_FREQ is used
   *	to specify the frequence of the channel in MHz. %NL80211_ATTR_AUTH_TYPE
   *	is used to specify the authentication type. %NL80211_ATTR_IE is used to
   *	define IEs (VendorSpecificInfo, but also including RSN IE and FT IEs)
   *	to be added to the frame.
   *	When used as an event, this reports reception of an Authentication
   *	frame in station and IBSS modes when the local MLME processed the
   *	frame, i.e., it was for the local STA and was received in correct
   *	state. This is similar to MLME-AUTHENTICATE.confirm primitive in the
   *	MLME SAP interface (kernel providing MLME, userspace SME). The
   *	included %NL80211_ATTR_FRAME attribute contains the management frame
   *	(including both the header and frame body, but not FCS). This event is
   *	also used to indicate if the authentication attempt timed out. In that
   *	case the %NL80211_ATTR_FRAME attribute is replaced with a
   *	%NL80211_ATTR_TIMED_OUT flag (and %NL80211_ATTR_MAC to indicate which
   *	pending authentication timed out).
   * @NL80211_CMD_ASSOCIATE: association request and notification; like
   *	NL80211_CMD_AUTHENTICATE but for Association and Reassociation
   *	(similar to MLME-ASSOCIATE.request, MLME-REASSOCIATE.request,
   *	MLME-ASSOCIATE.confirm or MLME-REASSOCIATE.confirm primitives).
   * @NL80211_CMD_DEAUTHENTICATE: deauthentication request and notification; like
   *	NL80211_CMD_AUTHENTICATE but for Deauthentication frames (similar to
   *	MLME-DEAUTHENTICATION.request and MLME-DEAUTHENTICATE.indication
   *	primitives).
   * @NL80211_CMD_DISASSOCIATE: disassociation request and notification; like
   *	NL80211_CMD_AUTHENTICATE but for Disassociation frames (similar to
   *	MLME-DISASSOCIATE.request and MLME-DISASSOCIATE.indication primitives).
   *
   * @NL80211_CMD_MICHAEL_MIC_FAILURE: notification of a locally detected Michael
   *	MIC (part of TKIP) failure; sent on the "mlme" multicast group; the
   *	event includes %NL80211_ATTR_MAC to describe the source MAC address of
   *	the frame with invalid MIC, %NL80211_ATTR_KEY_TYPE to show the key
   *	type, %NL80211_ATTR_KEY_IDX to indicate the key identifier, and
   *	%NL80211_ATTR_KEY_SEQ to indicate the TSC value of the frame; this
   *	event matches with MLME-MICHAELMICFAILURE.indication() primitive
   *
   * @NL80211_CMD_JOIN_IBSS: Join a new IBSS -- given at least an SSID and a
   *	FREQ attribute (for the initial frequency if no peer can be found)
   *	and optionally a MAC (as BSSID) and FREQ_FIXED attribute if those
   *	should be fixed rather than automatically determined. Can only be
   *	executed on a network interface that is UP, and fixed BSSID/FREQ
   *	may be rejected. Another optional parameter is the beacon interval,
   *	given in the %NL80211_ATTR_BEACON_INTERVAL attribute, which if not
   *	given defaults to 100 TU (102.4ms).
   * @NL80211_CMD_LEAVE_IBSS: Leave the IBSS -- no special arguments, the IBSS is
   *	determined by the network interface.
   *
   * @NL80211_CMD_TESTMODE: testmode command, takes a wiphy (or ifindex) attribute
   *	to identify the device, and the TESTDATA blob attribute to pass through
   *	to the driver.
   *
   * @NL80211_CMD_CONNECT: connection request and notification; this command
   *	requests to connect to a specified network but without separating
   *	auth and assoc steps. For this, you need to specify the SSID in a
   *	%NL80211_ATTR_SSID attribute, and can optionally specify the association
   *	IEs in %NL80211_ATTR_IE, %NL80211_ATTR_AUTH_TYPE, %NL80211_ATTR_USE_MFP,
   *	%NL80211_ATTR_MAC, %NL80211_ATTR_WIPHY_FREQ, %NL80211_ATTR_CONTROL_PORT,
   *	%NL80211_ATTR_CONTROL_PORT_ETHERTYPE and
   *	%NL80211_ATTR_CONTROL_PORT_NO_ENCRYPT.
   *	Background scan period can optionally be
   *	specified in %NL80211_ATTR_BG_SCAN_PERIOD,
   *	if not specified default background scan configuration
   *	in driver is used and if period value is 0, bg scan will be disabled.
   *	This attribute is ignored if driver does not support roam scan.
   *	It is also sent as an event, with the BSSID and response IEs when the
   *	connection is established or failed to be established. This can be
   *	determined by the STATUS_CODE attribute.
   * @NL80211_CMD_ROAM: request that the card roam (currently not implemented),
   *	sent as an event when the card/driver roamed by itself.
   * @NL80211_CMD_DISCONNECT: drop a given connection; also used to notify
   *	userspace that a connection was dropped by the AP or due to other
   *	reasons, for this the %NL80211_ATTR_DISCONNECTED_BY_AP and
   *	%NL80211_ATTR_REASON_CODE attributes are used.
   *
   * @NL80211_CMD_SET_WIPHY_NETNS: Set a wiphy's netns. Note that all devices
   *	associated with this wiphy must be down and will follow.
   *
   * @NL80211_CMD_REMAIN_ON_CHANNEL: Request to remain awake on the specified
   *	channel for the specified amount of time. This can be used to do
   *	off-channel operations like transmit a Public Action frame and wait for
   *	a response while being associated to an AP on another channel.
   *	%NL80211_ATTR_IFINDEX is used to specify which interface (and thus
   *	radio) is used. %NL80211_ATTR_WIPHY_FREQ is used to specify the
   *	frequency for the operation.
   *	%NL80211_ATTR_DURATION is used to specify the duration in milliseconds
   *	to remain on the channel. This command is also used as an event to
   *	notify when the requested duration starts (it may take a while for the
   *	driver to schedule this time due to other concurrent needs for the
   *	radio).
   *	When called, this operation returns a cookie (%NL80211_ATTR_COOKIE)
   *	that will be included with any events pertaining to this request;
   *	the cookie is also used to cancel the request.
   * @NL80211_CMD_CANCEL_REMAIN_ON_CHANNEL: This command can be used to cancel a
   *	pending remain-on-channel duration if the desired operation has been
   *	completed prior to expiration of the originally requested duration.
   *	%NL80211_ATTR_WIPHY or %NL80211_ATTR_IFINDEX is used to specify the
   *	radio. The %NL80211_ATTR_COOKIE attribute must be given as well to
   *	uniquely identify the request.
   *	This command is also used as an event to notify when a requested
   *	remain-on-channel duration has expired.
   *
   * @NL80211_CMD_SET_TX_BITRATE_MASK: Set the mask of rates to be used in TX
   *	rate selection. %NL80211_ATTR_IFINDEX is used to specify the interface
   *	and @NL80211_ATTR_TX_RATES the set of allowed rates.
   *
   * @NL80211_CMD_REGISTER_FRAME: Register for receiving certain mgmt frames
   *	(via @NL80211_CMD_FRAME) for processing in userspace. This command
   *	requires an interface index, a frame type attribute (optional for
   *	backward compatibility reasons, if not given assumes action frames)
   *	and a match attribute containing the first few bytes of the frame
   *	that should match, e.g. a single byte for only a category match or
   *	four bytes for vendor frames including the OUI. The registration
   *	cannot be dropped, but is removed automatically when the netlink
   *	socket is closed. Multiple registrations can be made.
   * @NL80211_CMD_REGISTER_ACTION: Alias for @NL80211_CMD_REGISTER_FRAME for
   *	backward compatibility
   * @NL80211_CMD_FRAME: Management frame TX request and RX notification. This
   *	command is used both as a request to transmit a management frame and
   *	as an event indicating reception of a frame that was not processed in
   *	kernel code, but is for us (i.e., which may need to be processed in a
   *	user space application). %NL80211_ATTR_FRAME is used to specify the
   *	frame contents (including header). %NL80211_ATTR_WIPHY_FREQ is used
   *	to indicate on which channel the frame is to be transmitted or was
   *	received. If this channel is not the current channel (remain-on-channel
   *	or the operational channel) the device will switch to the given channel
   *	and transmit the frame, optionally waiting for a response for the time
   *	specified using %NL80211_ATTR_DURATION. When called, this operation
   *	returns a cookie (%NL80211_ATTR_COOKIE) that will be included with the
   *	TX status event pertaining to the TX request.
   *	%NL80211_ATTR_TX_NO_CCK_RATE is used to decide whether to send the
   *	management frames at CCK rate or not in 2GHz band.
   * @NL80211_CMD_FRAME_WAIT_CANCEL: When an off-channel TX was requested, this
   *	command may be used with the corresponding cookie to cancel the wait
   *	time if it is known that it is no longer necessary.
   * @NL80211_CMD_ACTION: Alias for @NL80211_CMD_FRAME for backward compatibility.
   * @NL80211_CMD_FRAME_TX_STATUS: Report TX status of a management frame
   *	transmitted with %NL80211_CMD_FRAME. %NL80211_ATTR_COOKIE identifies
   *	the TX command and %NL80211_ATTR_FRAME includes the contents of the
   *	frame. %NL80211_ATTR_ACK flag is included if the recipient acknowledged
   *	the frame.
   * @NL80211_CMD_ACTION_TX_STATUS: Alias for @NL80211_CMD_FRAME_TX_STATUS for
   *	backward compatibility.
   *
   * @NL80211_CMD_SET_POWER_SAVE: Set powersave, using %NL80211_ATTR_PS_STATE
   * @NL80211_CMD_GET_POWER_SAVE: Get powersave status in %NL80211_ATTR_PS_STATE
   *
   * @NL80211_CMD_SET_CQM: Connection quality monitor configuration. This command
   *	is used to configure connection quality monitoring notification trigger
   *	levels.
   * @NL80211_CMD_NOTIFY_CQM: Connection quality monitor notification. This
   *	command is used as an event to indicate the that a trigger level was
   *	reached.
   * @NL80211_CMD_SET_CHANNEL: Set the channel (using %NL80211_ATTR_WIPHY_FREQ
   *	and the attributes determining channel width) the given interface
   *	(identifed by %NL80211_ATTR_IFINDEX) shall operate on.
   *	In case multiple channels are supported by the device, the mechanism
   *	with which it switches channels is implementation-defined.
   *	When a monitor interface is given, it can only switch channel while
   *	no other interfaces are operating to avoid disturbing the operation
   *	of any other interfaces, and other interfaces will again take
   *	precedence when they are used.
   *
   * @NL80211_CMD_SET_WDS_PEER: Set the MAC address of the peer on a WDS interface.
   *
   * @NL80211_CMD_JOIN_MESH: Join a mesh. The mesh ID must be given, and initial
   *	mesh config parameters may be given.
   * @NL80211_CMD_LEAVE_MESH: Leave the mesh network -- no special arguments, the
   *	network is determined by the network interface.
   *
   * @NL80211_CMD_UNPROT_DEAUTHENTICATE: Unprotected deauthentication frame
   *	notification. This event is used to indicate that an unprotected
   *	deauthentication frame was dropped when MFP is in use.
   * @NL80211_CMD_UNPROT_DISASSOCIATE: Unprotected disassociation frame
   *	notification. This event is used to indicate that an unprotected
   *	disassociation frame was dropped when MFP is in use.
   *
   * @NL80211_CMD_NEW_PEER_CANDIDATE: Notification on the reception of a
   *      beacon or probe response from a compatible mesh peer.  This is only
   *      sent while no station information (sta_info) exists for the new peer
   *      candidate and when @NL80211_MESH_SETUP_USERSPACE_AUTH,
   *      @NL80211_MESH_SETUP_USERSPACE_AMPE, or
   *      @NL80211_MESH_SETUP_USERSPACE_MPM is set.  On reception of this
   *      notification, userspace may decide to create a new station
   *      (@NL80211_CMD_NEW_STATION).  To stop this notification from
   *      reoccurring, the userspace authentication daemon may want to create the
   *      new station with the AUTHENTICATED flag unset and maybe change it later
   *      depending on the authentication result.
   *
   * @NL80211_CMD_GET_WOWLAN: get Wake-on-Wireless-LAN (WoWLAN) settings.
   * @NL80211_CMD_SET_WOWLAN: set Wake-on-Wireless-LAN (WoWLAN) settings.
   *	Since wireless is more complex than wired ethernet, it supports
   *	various triggers. These triggers can be configured through this
   *	command with the %NL80211_ATTR_WOWLAN_TRIGGERS attribute. For
   *	more background information, see
   *	http://wireless.kernel.org/en/users/Documentation/WoWLAN.
   *	The @NL80211_CMD_SET_WOWLAN command can also be used as a notification
   *	from the driver reporting the wakeup reason. In this case, the
   *	@NL80211_ATTR_WOWLAN_TRIGGERS attribute will contain the reason
   *	for the wakeup, if it was caused by wireless. If it is not present
   *	in the wakeup notification, the wireless device didn't cause the
   *	wakeup but reports that it was woken up.
   *
   * @NL80211_CMD_SET_REKEY_OFFLOAD: This command is used give the driver
   *	the necessary information for supporting GTK rekey offload. This
   *	feature is typically used during WoWLAN. The configuration data
   *	is contained in %NL80211_ATTR_REKEY_DATA (which is nested and
   *	contains the data in sub-attributes). After rekeying happened,
   *	this command may also be sent by the driver as an MLME event to
   *	inform userspace of the new replay counter.
   *
   * @NL80211_CMD_PMKSA_CANDIDATE: This is used as an event to inform userspace
   *	of PMKSA caching dandidates.
   *
   * @NL80211_CMD_TDLS_OPER: Perform a high-level TDLS command (e.g. link setup).
   *	In addition, this can be used as an event to request userspace to take
   *	actions on TDLS links (set up a new link or tear down an existing one).
   *	In such events, %NL80211_ATTR_TDLS_OPERATION indicates the requested
   *	operation, %NL80211_ATTR_MAC contains the peer MAC address, and
   *	%NL80211_ATTR_REASON_CODE the reason code to be used (only with
   *	%NL80211_TDLS_TEARDOWN).
   * @NL80211_CMD_TDLS_MGMT: Send a TDLS management frame.
   *
   * @NL80211_CMD_UNEXPECTED_FRAME: Used by an application controlling an AP
   *	(or GO) interface (i.e. hostapd) to ask for unexpected frames to
   *	implement sending deauth to stations that send unexpected class 3
   *	frames. Also used as the event sent by the kernel when such a frame
   *	is received.
   *	For the event, the %NL80211_ATTR_MAC attribute carries the TA and
   *	other attributes like the interface index are present.
   *	If used as the command it must have an interface index and you can
   *	only unsubscribe from the event by closing the socket. Subscription
   *	is also for %NL80211_CMD_UNEXPECTED_4ADDR_FRAME events.
   *
   * @NL80211_CMD_UNEXPECTED_4ADDR_FRAME: Sent as an event indicating that the
   *	associated station identified by %NL80211_ATTR_MAC sent a 4addr frame
   *	and wasn't already in a 4-addr VLAN. The event will be sent similarly
   *	to the %NL80211_CMD_UNEXPECTED_FRAME event, to the same listener.
   *
   * @NL80211_CMD_PROBE_CLIENT: Probe an associated station on an AP interface
   *	by sending a null data frame to it and reporting when the frame is
   *	acknowleged. This is used to allow timing out inactive clients. Uses
   *	%NL80211_ATTR_IFINDEX and %NL80211_ATTR_MAC. The command returns a
   *	direct reply with an %NL80211_ATTR_COOKIE that is later used to match
   *	up the event with the request. The event includes the same data and
   *	has %NL80211_ATTR_ACK set if the frame was ACKed.
   *
   * @NL80211_CMD_REGISTER_BEACONS: Register this socket to receive beacons from
   *	other BSSes when any interfaces are in AP mode. This helps implement
   *	OLBC handling in hostapd. Beacons are reported in %NL80211_CMD_FRAME
   *	messages. Note that per PHY only one application may register.
   *
   * @NL80211_CMD_SET_NOACK_MAP: sets a bitmap for the individual TIDs whether
   *      No Acknowledgement Policy should be applied.
   *
   * @NL80211_CMD_CH_SWITCH_NOTIFY: An AP or GO may decide to switch channels
   *	independently of the userspace SME, send this event indicating
   *	%NL80211_ATTR_IFINDEX is now on %NL80211_ATTR_WIPHY_FREQ and the
   *	attributes determining channel width.
   *
   * @NL80211_CMD_START_P2P_DEVICE: Start the given P2P Device, identified by
   *	its %NL80211_ATTR_WDEV identifier. It must have been created with
   *	%NL80211_CMD_NEW_INTERFACE previously. After it has been started, the
   *	P2P Device can be used for P2P operations, e.g. remain-on-channel and
   *	public action frame TX.
   * @NL80211_CMD_STOP_P2P_DEVICE: Stop the given P2P Device, identified by
   *	its %NL80211_ATTR_WDEV identifier.
   *
   * @NL80211_CMD_CONN_FAILED: connection request to an AP failed; used to
   *	notify userspace that AP has rejected the connection request from a
   *	station, due to particular reason. %NL80211_ATTR_CONN_FAILED_REASON
   *	is used for this.
   *
   * @NL80211_CMD_SET_MCAST_RATE: Change the rate used to send multicast frames
   *	for IBSS or MESH vif.
   *
   * @NL80211_CMD_SET_MAC_ACL: sets ACL for MAC address based access control.
   *	This is to be used with the drivers advertising the support of MAC
   *	address based access control. List of MAC addresses is passed in
   *	%NL80211_ATTR_MAC_ADDRS and ACL policy is passed in
   *	%NL80211_ATTR_ACL_POLICY. Driver will enable ACL with this list, if it
   *	is not already done. The new list will replace any existing list. Driver
   *	will clear its ACL when the list of MAC addresses passed is empty. This
   *	command is used in AP/P2P GO mode. Driver has to make sure to clear its
   *	ACL list during %NL80211_CMD_STOP_AP.
   *
   * @NL80211_CMD_RADAR_DETECT: Start a Channel availability check (CAC). Once
   *	a radar is detected or the channel availability scan (CAC) has finished
   *	or was aborted, or a radar was detected, usermode will be notified with
   *	this event. This command is also used to notify userspace about radars
   *	while operating on this channel.
   *	%NL80211_ATTR_RADAR_EVENT is used to inform about the type of the
   *	event.
   *
   * @NL80211_CMD_GET_PROTOCOL_FEATURES: Get global nl80211 protocol features,
   *	i.e. features for the nl80211 protocol rather than device features.
   *	Returns the features in the %NL80211_ATTR_PROTOCOL_FEATURES bitmap.
   *
   * @NL80211_CMD_UPDATE_FT_IES: Pass down the most up-to-date Fast Transition
   *	Information Element to the WLAN driver
   *
   * @NL80211_CMD_FT_EVENT: Send a Fast transition event from the WLAN driver
   *	to the supplicant. This will carry the target AP's MAC address along
   *	with the relevant Information Elements. This event is used to report
   *	received FT IEs (MDIE, FTIE, RSN IE, TIE, RICIE).
   *
   * @NL80211_CMD_CRIT_PROTOCOL_START: Indicates user-space will start running
   *	a critical protocol that needs more reliability in the connection to
   *	complete.
   *
   * @NL80211_CMD_CRIT_PROTOCOL_STOP: Indicates the connection reliability can
   *	return back to normal.
   *
   * @NL80211_CMD_MAX: highest used command number
   * @__NL80211_CMD_AFTER_LAST: internal use

   *	used by %NL80211_CMD_GET_WOWLAN to get the currently enabled WoWLAN
   *	triggers.
   *
   * @NL80211_ATTR_SCHED_SCAN_INTERVAL: Interval between scheduled scan
   *	cycles, in msecs.
   *
   * @NL80211_ATTR_SCHED_SCAN_MATCH: Nested attribute with one or more
   *	sets of attributes to match during scheduled scans.  Only BSSs
   *	that match any of the sets will be reported.  These are
   *	pass-thru filter rules.
   *	For a match to succeed, the BSS must match all attributes of a
   *	set.  Since not every hardware supports matching all types of
   *	attributes, there is no guarantee that the reported BSSs are
   *	fully complying with the match sets and userspace needs to be
   *	able to ignore them by itself.
   *	Thus, the implementation is somewhat hardware-dependent, but
   *	this is only an optimization and the userspace application
   *	needs to handle all the non-filtered results anyway.
   *	If the match attributes don't make sense when combined with
   *	the values passed in @NL80211_ATTR_SCAN_SSIDS (eg. if an SSID
   *	is included in the probe request, but the match attributes
   *	will never let it go through), -EINVAL may be returned.
   *	If ommited, no filtering is done.
   *
   * @NL80211_ATTR_INTERFACE_COMBINATIONS: Nested attribute listing the supported
   *	interface combinations. In each nested item, it contains attributes
   *	defined in &enum nl80211_if_combination_attrs.
   * @NL80211_ATTR_SOFTWARE_IFTYPES: Nested attribute (just like
   *	%NL80211_ATTR_SUPPORTED_IFTYPES) containing the interface types that
   *	are managed in software: interfaces of these types aren't subject to
   *	any restrictions in their number or combinations.
   *
   * @NL80211_ATTR_REKEY_DATA: nested attribute containing the information

   *
   * @NL80211_ATTR_SCAN_SUPP_RATES: rates per to be advertised as supported in scan,
   *	nested array attribute containing an entry for each band, with the entry
   *	being a list of supported rates as defined by IEEE 802.11 7.3.2.2 but
   *	without the length restriction (at most %NL80211_MAX_SUPP_RATES).
   *
   * @NL80211_ATTR_HIDDEN_SSID: indicates whether SSID is to be hidden from Beacon
   *	and Probe Response (when response to wildcard Probe Request); see
   *	&enum nl80211_hidden_ssid, represented as a u32
   *
   * @NL80211_ATTR_IE_PROBE_RESP: Information element(s) for Probe Response frame.
   *	This is used with %NL80211_CMD_NEW_BEACON and %NL80211_CMD_SET_BEACON to
   *	provide extra IEs (e.g., WPS/P2P IE) into Probe Response frames when the
   *	driver (or firmware) replies to Probe Request frames.
   * @NL80211_ATTR_IE_ASSOC_RESP: Information element(s) for (Re)Association
   *	Response frames. This is used with %NL80211_CMD_NEW_BEACON and
   *	%NL80211_CMD_SET_BEACON to provide extra IEs (e.g., WPS/P2P IE) into
   *	(Re)Association Response frames when the driver (or firmware) replies to
   *	(Re)Association Request frames.
   *
   * @NL80211_ATTR_STA_WME: Nested attribute containing the wme configuration
   *	of the station, see &enum nl80211_sta_wme_attr.

   *	as AP.
   *
   * @NL80211_ATTR_ROAM_SUPPORT: Indicates whether the firmware is capable of

   *
   * @NL80211_ATTR_PMKSA_CANDIDATE: Nested attribute containing the PMKSA caching
   *	candidate information, see &enum nl80211_pmksa_candidate_attr.
   *
   * @NL80211_ATTR_TX_NO_CCK_RATE: Indicates whether to use CCK rate or not
   *	for management frames transmission. In order to avoid p2p probe/action
   *	frames are being transmitted at CCK rate in 2GHz band, the user space
   *	applications use this attribute.
   *	This attribute is used with %NL80211_CMD_TRIGGER_SCAN and
   *	%NL80211_CMD_FRAME commands.
   *
   * @NL80211_ATTR_TDLS_ACTION: Low level TDLS action code (e.g. link setup

   * @NL80211_ATTR_TDLS_EXTERNAL_SETUP: The TDLS discovery/setup and teardown
   *	procedures should be performed by sending TDLS packets via
   *	%NL80211_CMD_TDLS_MGMT. Otherwise %NL80211_CMD_TDLS_OPER should be
   *	used for asking the driver to perform a TDLS operation.
   *
   * @NL80211_ATTR_DEVICE_AP_SME: This u32 attribute may be listed for devices
   *	that have AP support to indicate that they have the AP SME integrated
   *	with support for the features listed in this attribute, see
   *	&enum nl80211_ap_sme_features.
   *
   * @NL80211_ATTR_DONT_WAIT_FOR_ACK: Used with %NL80211_CMD_FRAME, this tells
   *	the driver to not wait for an acknowledgement. Note that due to this,

   *	probe-response frame. The DA field in the 802.11 header is zero-ed out,
   *	to be filled by the FW.
   * @NL80211_ATTR_DISABLE_HT:  Force HT capable interfaces to disable
   *      this feature.  Currently, only supported in mac80211 drivers.
   * @NL80211_ATTR_HT_CAPABILITY_MASK: Specify which bits of the
   *      ATTR_HT_CAPABILITY to which attention should be paid.
   *      Currently, only mac80211 NICs support this feature.
   *      The values that may be configured are:
   *       MCS rates, MAX-AMSDU, HT-20-40 and HT_CAP_SGI_40
   *       AMPDU density and AMPDU factor.
   *      All values are treated as suggestions and may be ignored
   *      by the driver as required.  The actual values may be seen in
   *      the station debugfs ht_caps file.
   *
   * @NL80211_ATTR_DFS_REGION: region for regulatory rules which this country
   *    abides to when initiating radiation on DFS channels. A country maps

   *	capability to timeout the stations.
   *
   * @NL80211_ATTR_RX_SIGNAL_DBM: signal strength in dBm (as a 32-bit int);
   *	this attribute is (depending on the driver capabilities) added to

   *
   * @NL80211_ATTR_BG_SCAN_PERIOD: Background scan period in seconds
   *      or 0 to disable background scan.
   *
   * @NL80211_ATTR_USER_REG_HINT_TYPE: type of regulatory hint passed from
   *	userspace. If unset it is assumed the hint comes directly from

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

   * @NL80211_FEATURE_SK_TX_STATUS: This driver supports reflecting back
   *	TX status to the socket error queue when requested with the
   *	socket option.
   * @NL80211_FEATURE_HT_IBSS: This driver supports IBSS with HT datarates.
   * @NL80211_FEATURE_INACTIVITY_TIMER: This driver takes care of freeing up
   *	the connected inactive stations in AP mode.
   * @NL80211_FEATURE_CELL_BASE_REG_HINTS: This driver has been tested
   *	to work properly to suppport receiving regulatory hints from
   *	cellular base stations.
   * @NL80211_FEATURE_P2P_DEVICE_NEEDS_CHANNEL: If this is set, an active
   *	P2P Device (%NL80211_IFTYPE_P2P_DEVICE) requires its own channel
   *	in the interface combinations, even when it's only used for scan
   *	and remain-on-channel. This could be due to, for example, the
   *	remain-on-channel implementation requiring a channel context.
   * @NL80211_FEATURE_SAE: This driver supports simultaneous authentication of
   *	equals (SAE) with user space SME (NL80211_CMD_AUTHENTICATE) in station
   *	mode
   * @NL80211_FEATURE_LOW_PRIORITY_SCAN: This driver supports low priority scan
   * @NL80211_FEATURE_SCAN_FLUSH: Scan flush is supported
   * @NL80211_FEATURE_AP_SCAN: Support scanning using an AP vif
   * @NL80211_FEATURE_VIF_TXPOWER: The driver supports per-vif TX power setting
   * @NL80211_FEATURE_NEED_OBSS_SCAN: The driver expects userspace to perform
   *	OBSS scans and generate 20/40 BSS coex reports. This flag is used only
   *	for drivers implementing the CONNECT API, for AUTH/ASSOC it is implied.
   * @NL80211_FEATURE_P2P_GO_CTWIN: P2P GO implementation supports CT Window
   *	setting
   * @NL80211_FEATURE_P2P_GO_OPPPS: P2P GO implementation supports opportunistic
   *	powersave
   * @NL80211_FEATURE_FULL_AP_CLIENT_STATE: The driver supports full state
   *	transitions for AP clients. Without this flag (and if the driver
   *	doesn't have the AP SME in the device) the driver supports adding
   *	stations only when they're associated and adds them in associated
   *	state (to later be transitioned into authorized), with this flag
   *	they should be added before even sending the authentication reply
   *	and then transitioned into authenticated, associated and authorized
   *	states using station flags.
   *	Note that even for drivers that support this, the default is to add
   *	stations in authenticated/associated state, so to add unauthenticated
   *	stations the authenticated/associated bits have to be set in the mask.
   * @NL80211_FEATURE_ADVERTISE_CHAN_LIMITS: cfg80211 advertises channel limits
   *	(HT40, VHT 80/160 MHz) if this flag is set
   * @NL80211_FEATURE_USERSPACE_MPM: This driver supports a userspace Mesh
   *	Peering Management entity which may be implemented by registering for
   *	beacons or NL80211_CMD_NEW_PEER_CANDIDATE events. The mesh beacon is
   *	still generated by the driver.
