+ * DOC: Station handling

+ * into a VLAN identified by a VLAN interface index (%NL80211_ATTR_STA_VLAN).

+
+/**
+ * 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_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_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_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_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_MAC,
+ *	%NL80211_ATTR_WIPHY_FREQ, %NL80211_ATTR_CONTROL_PORT,
+ *	%NL80211_ATTR_CONTROL_PORT_ETHERTYPE and
+ *	%NL80211_ATTR_CONTROL_PORT_NO_ENCRYPT.
+ *	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 and %NL80211_ATTR_WIPHY_CHANNEL_TYPE may be
+ *	optionally used to specify additional channel parameters.
+ *	%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 (and
+ *	optionally %NL80211_ATTR_WIPHY_CHANNEL_TYPE) 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_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_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.
+ *
+ * @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_MAX: highest used command number
+ * @__NL80211_CMD_AFTER_LAST: internal use

+ *	(enum nl80211_tx_rate_attributes) describing TX rates per band. The
+ *	enum nl80211_band value is used as the index (nla_type() of the nested
+ *	data. If a band is not included, it will be configured to allow all
+ *	rates based on negotiated supported rates information. This attribute
+ *	is used with %NL80211_CMD_SET_TX_BITRATE_MASK.
+ *
+ * @NL80211_ATTR_FRAME_MATCH: A binary attribute which typically must contain
+ *	at least one byte, currently used with @NL80211_CMD_REGISTER_FRAME.
+ * @NL80211_ATTR_FRAME_TYPE: A u16 indicating the frame type/subtype for the
+ *	@NL80211_CMD_REGISTER_FRAME command.
+ * @NL80211_ATTR_TX_FRAME_TYPES: wiphy capability attribute, which is a
+ *	nested attribute of %NL80211_ATTR_FRAME_TYPE attributes, containing
+ *	information about which frame types can be transmitted with
+ *	%NL80211_CMD_FRAME.
+ * @NL80211_ATTR_RX_FRAME_TYPES: wiphy capability attribute, which is a
+ *	nested attribute of %NL80211_ATTR_FRAME_TYPE attributes, containing
+ *	information about which frame types can be registered for RX.
+ *
+ * @NL80211_ATTR_ACK: Flag attribute indicating that the frame was
+ *	acknowledged by the recipient.
+ *
+ * @NL80211_ATTR_CQM: connection quality monitor configuration in a
+ *	nested attribute with %NL80211_ATTR_CQM_* sub-attributes.
+ *
+ * @NL80211_ATTR_LOCAL_STATE_CHANGE: Flag attribute to indicate that a command
+ *	is requesting a local authentication/association state change without
+ *	invoking actual management frame exchange. This can be used with
+ *	NL80211_CMD_AUTHENTICATE, NL80211_CMD_DEAUTHENTICATE,
+ *	NL80211_CMD_DISASSOCIATE.
+ *
+ * @NL80211_ATTR_AP_ISOLATE: (AP mode) Do not forward traffic between stations
+ *	connected to this BSS.
+ *
+ * @NL80211_ATTR_WIPHY_TX_POWER_SETTING: Transmit power setting type. See
+ *      &enum nl80211_tx_power_setting for possible values.
+ * @NL80211_ATTR_WIPHY_TX_POWER_LEVEL: Transmit power level in signed mBm units.
+ *      This is used in association with @NL80211_ATTR_WIPHY_TX_POWER_SETTING
+ *      for non-automatic settings.
+ *
+ * @NL80211_ATTR_SUPPORT_IBSS_RSN: The device supports IBSS RSN, which mostly
+ *	means support for per-station GTKs.
+ *
+ * @NL80211_ATTR_WIPHY_ANTENNA_TX: Bitmap of allowed antennas for transmitting.
+ *	This can be used to mask out antennas which are not attached or should
+ *	not be used for transmitting. If an antenna is not selected in this
+ *	bitmap the hardware is not allowed to transmit on this antenna.
+ *
+ *	Each bit represents one antenna, starting with antenna 1 at the first
+ *	bit. Depending on which antennas are selected in the bitmap, 802.11n
+ *	drivers can derive which chainmasks to use (if all antennas belonging to
+ *	a particular chain are disabled this chain should be disabled) and if
+ *	a chain has diversity antennas whether diversity should be used or not.
+ *	HT capabilities (STBC, TX Beamforming, Antenna selection) can be
+ *	derived from the available chains after applying the antenna mask.
+ *	Non-802.11n drivers can derive wether to use diversity or not.
+ *	Drivers may reject configurations or RX/TX mask combinations they cannot
+ *	support by returning -EINVAL.
+ *
+ * @NL80211_ATTR_WIPHY_ANTENNA_RX: Bitmap of allowed antennas for receiving.
+ *	This can be used to mask out antennas which are not attached or should
+ *	not be used for receiving. If an antenna is not selected in this bitmap
+ *	the hardware should not be configured to receive on this antenna.
+ *	For a more detailed description see @NL80211_ATTR_WIPHY_ANTENNA_TX.
+ *
+ * @NL80211_ATTR_MCAST_RATE: Multicast tx rate (in 100 kbps) for IBSS
+ *
+ * @NL80211_ATTR_OFFCHANNEL_TX_OK: For management frame TX, the frame may be
+ *	transmitted on another channel when the channel given doesn't match
+ *	the current channel. If the current channel doesn't match and this
+ *	flag isn't set, the frame will be rejected. This is also used as an
