/**
 * 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.

 * @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
248
249
250
251
 *	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
252
253
254
255
256
257
 *	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).
258
259
260
261
262
 * @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
263
 *	NL80211_CMD_AUTHENTICATE but for Deauthentication frames (similar to
264
265
266
 *	MLME-DEAUTHENTICATION.request and MLME-DEAUTHENTICATE.indication
 *	primitives).
 * @NL80211_CMD_DISASSOCIATE: disassociation request and notification; like
267
 *	NL80211_CMD_AUTHENTICATE but for Disassociation frames (similar to
268
 *	MLME-DISASSOCIATE.request and MLME-DISASSOCIATE.indication primitives).

275
276
277
 * @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

 *	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.
 *
339
340
341
342
 * @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.
352
353
 * @NL80211_CMD_REGISTER_ACTION: Alias for @NL80211_CMD_REGISTER_FRAME for
 *	backward compatibility
354
355
356
 * @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
357
358
359
360
 *	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 (and
 *	optionally %NL80211_ATTR_WIPHY_CHANNEL_TYPE) is used to indicate on

368
369
370
 *	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_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.
371
 * @NL80211_CMD_ACTION: Alias for @NL80211_CMD_FRAME for backward compatibility.
372
373
 * @NL80211_CMD_FRAME_TX_STATUS: Report TX status of a management frame
 *	transmitted with %NL80211_CMD_FRAME. %NL80211_ATTR_COOKIE identifies
374
375
376
 *	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.
377
378
 * @NL80211_CMD_ACTION_TX_STATUS: Alias for @NL80211_CMD_FRAME_TX_STATUS for
 *	backward compatibility.
379
380
381
382
383
384
 * @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 %NL80211_ATTR_WIPHY_CHANNEL_TYPE) 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.
394
 *
395
396
 * @NL80211_CMD_SET_WDS_PEER: Set the MAC address of the peer on a WDS interface.
 *
397
398
399
400
401
 * @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.
