+ * 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

+ * 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.

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

+ *	%NL80211_ATTR_IFINDEX.
+ *
+ * @NL80211_CMD_GET_REG: ask the wireless core to send us its currently set
+ *	regulatory domain. If %NL80211_ATTR_WIPHY is specified and the device
+ *	has a private regulatory domain, it will be returned. Otherwise, the
+ *	global regdomain will be returned.
+ *	A device will have a private regulatory domain if it uses the
+ *	regulatory_hint() API. Even when a private regdomain is used the channel
+ *	information will still be mended according to further hints from
+ *	the regulatory core to help with compliance. A dump version of this API
+ *	is now available which will returns the global regdomain as well as
+ *	all private regdomains of present wiphys (for those that have it).
+ *	If a wiphy is self-managed (%NL80211_ATTR_WIPHY_SELF_MANAGED_REG), then
+ *	its private regdomain is the only valid one for it. The regulatory
+ *	core is not used to help with compliance in this case.
+ * @NL80211_CMD_SET_REG: Set current regulatory domain. CRDA sends this command
+ *	after being queried by the kernel. CRDA replies by sending a regulatory
+ *	domain structure which consists of %NL80211_ATTR_REG_ALPHA set to our
+ *	current alpha2 if it found a match. It also provides
+ * 	NL80211_ATTR_REG_RULE_FLAGS, and a set of regulatory rules. Each
+ * 	regulatory rule is a nested set of attributes  given by
+ * 	%NL80211_ATTR_REG_RULE_FREQ_[START|END] and
+ * 	%NL80211_ATTR_FREQ_RANGE_MAX_BW with an attached power rule given by

+ * 	%NL80211_ATTR_REG_RULE_POWER_MAX_EIRP.
+ * @NL80211_CMD_REQ_SET_REG: ask the wireless core to set the regulatory domain
+ * 	to the specified ISO/IEC 3166-1 alpha2 country code. The core will
+ * 	store this as a valid request and then query userspace for it.
+ *
+ * @NL80211_CMD_GET_MESH_CONFIG: Get mesh networking properties for the
+ *	interface identified by %NL80211_ATTR_IFINDEX
+ *
+ * @NL80211_CMD_SET_MESH_CONFIG: Set mesh networking properties for the
+ *      interface identified by %NL80211_ATTR_IFINDEX
+ *
+ * @NL80211_CMD_SET_MGMT_EXTRA_IE: Set extra IEs for management frames. The
+ *	interface is identified with %NL80211_ATTR_IFINDEX and the management
+ *	frame subtype with %NL80211_ATTR_MGMT_SUBTYPE. The extra IE data to be
+ *	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.  The first cycle of the
+ *	scheduled scan can be delayed by %NL80211_ATTR_SCHED_SCAN_DELAY
+ *	is supplied.
+ * @NL80211_CMD_STOP_SCHED_SCAN: stop a scheduled scan. Returns -ENOENT if
+ *	scheduled scan is not running. The caller may assume that as soon
+ *	as the call returns, it is safe to start a new scheduled scan again.
+ * @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,
+ *	%NL80211_ATTR_CONTROL_PORT_NO_ENCRYPT, %NL80211_ATTR_MAC_HINT, and
+ *	%NL80211_ATTR_WIPHY_FREQ_HINT.
+ *	If included, %NL80211_ATTR_MAC and %NL80211_ATTR_WIPHY_FREQ are
+ *	restrictions on BSS selection, i.e., they effectively prevent roaming
+ *	within the ESS. %NL80211_ATTR_MAC_HINT and %NL80211_ATTR_WIPHY_FREQ_HINT
+ *	can be included to provide a recommendation of the initial BSS while
+ *	allowing the driver to roam to other BSSes within the ESS and also to
+ *	ignore this recommendation if the indicated BSS is not ideal. Only one
+ *	set of BSSID,frequency parameters is used (i.e., either the enforcing
+ *	%NL80211_ATTR_MAC,%NL80211_ATTR_WIPHY_FREQ or the less strict
+ *	%NL80211_ATTR_MAC_HINT and %NL80211_ATTR_WIPHY_FREQ_HINT).
+ *	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_ATTR_CSA_C_OFFSETS_TX is an array of offsets to CSA
+ *	counters which will be updated to the current value. This attribute
+ *	is used during CSA period.
+ * @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. The
+ *	%NL80211_ATTR_TDLS_ACTION attribute determines the type of frame to be
+ *	sent. Public Action codes (802.11-2012 8.1.5.1) will be sent as
+ *	802.11 management frames, while TDLS action codes (802.11-2012
+ *	8.5.13.1) will be encapsulated and sent as data frames. The currently
+ *	supported Public Action code is %WLAN_PUB_ACTION_TDLS_DISCOVER_RES
+ *	and the currently supported TDLS actions codes are given in
+ *	&enum ieee80211_tdls_actioncode.
+ *
+ * @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.  This indication may also be
+ *	sent when a remotely-initiated switch (e.g., when a STA receives a CSA
+ *	from the remote AP) is completed;
+ *
+ * @NL80211_CMD_CH_SWITCH_STARTED_NOTIFY: Notify that a channel switch
+ *	has been started on an interface, regardless of the initiator
+ *	(ie. whether it was requested from a remote device or
+ *	initiated on our own).  It indicates that
+ *	%NL80211_ATTR_IFINDEX will be on %NL80211_ATTR_WIPHY_FREQ
+ *	after %NL80211_ATTR_CH_SWITCH_COUNT TBTT's.  The userspace may
+ *	decide to react to this indication by requesting other
+ *	interfaces to change channel as well.
+ *
+ * @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_GET_COALESCE: Get currently supported coalesce rules.
+ * @NL80211_CMD_SET_COALESCE: Configure coalesce rules or clear existing rules.
+ *
+ * @NL80211_CMD_CHANNEL_SWITCH: Perform a channel switch by announcing the
+ *	the new channel information (Channel Switch Announcement - CSA)
+ *	in the beacon for some time (as defined in the
+ *	%NL80211_ATTR_CH_SWITCH_COUNT parameter) and then change to the
+ *	new channel. Userspace provides the new channel information (using
+ *	%NL80211_ATTR_WIPHY_FREQ and the attributes determining channel
+ *	width). %NL80211_ATTR_CH_SWITCH_BLOCK_TX may be supplied to inform
+ *	other station that transmission must be blocked until the channel
+ *	switch is complete.
+ *
+ * @NL80211_CMD_VENDOR: Vendor-specified command/event. The command is specified
+ *	by the %NL80211_ATTR_VENDOR_ID attribute and a sub-command in
+ *	%NL80211_ATTR_VENDOR_SUBCMD. Parameter(s) can be transported in
+ *	%NL80211_ATTR_VENDOR_DATA.
+ *	For feature advertisement, the %NL80211_ATTR_VENDOR_DATA attribute is
+ *	used in the wiphy data as a nested attribute containing descriptions
+ *	(&struct nl80211_vendor_cmd_info) of the supported vendor commands.
+ *	This may also be sent as an event with the same attributes.
+ *
+ * @NL80211_CMD_SET_QOS_MAP: Set Interworking QoS mapping for IP DSCP values.
+ *	The QoS mapping information is included in %NL80211_ATTR_QOS_MAP. If
+ *	that attribute is not included, QoS mapping is disabled. Since this
+ *	QoS mapping is relevant for IP packets, it is only valid during an
+ *	association. This is cleared on disassociation and AP restart.
+ *
+ * @NL80211_CMD_ADD_TX_TS: Ask the kernel to add a traffic stream for the given
+ *	%NL80211_ATTR_TSID and %NL80211_ATTR_MAC with %NL80211_ATTR_USER_PRIO
+ *	and %NL80211_ATTR_ADMITTED_TIME parameters.
+ *	Note that the action frame handshake with the AP shall be handled by
+ *	userspace via the normal management RX/TX framework, this only sets
+ *	up the TX TS in the driver/device.
+ *	If the admitted time attribute is not added then the request just checks
+ *	if a subsequent setup could be successful, the intent is to use this to
+ *	avoid setting up a session with the AP when local restrictions would
+ *	make that impossible. However, the subsequent "real" setup may still
+ *	fail even if the check was successful.
+ * @NL80211_CMD_DEL_TX_TS: Remove an existing TS with the %NL80211_ATTR_TSID
+ *	and %NL80211_ATTR_MAC parameters. It isn't necessary to call this
+ *	before removing a station entry entirely, or before disassociating
+ *	or similar, cleanup will happen in the driver/device in this case.
+ *
+ * @NL80211_CMD_GET_MPP: Get mesh path attributes for mesh proxy path to
+ *	destination %NL80211_ATTR_MAC on the interface identified by
+ *	%NL80211_ATTR_IFINDEX.
+ *
+ * @NL80211_CMD_JOIN_OCB: Join the OCB network. The center frequency and
+ *	bandwidth of a channel must be given.
+ * @NL80211_CMD_LEAVE_OCB: Leave the OCB network -- no special arguments, the
+ *	network is determined by the network interface.
+ *
+ * @NL80211_CMD_TDLS_CHANNEL_SWITCH: Start channel-switching with a TDLS peer,
+ *	identified by the %NL80211_ATTR_MAC parameter. A target channel is
+ *	provided via %NL80211_ATTR_WIPHY_FREQ and other attributes determining
+ *	channel width/type. The target operating class is given via
+ *	%NL80211_ATTR_OPER_CLASS.
+ *	The driver is responsible for continually initiating channel-switching
+ *	operations and returning to the base channel for communication with the
+ *	AP.
+ * @NL80211_CMD_TDLS_CANCEL_CHANNEL_SWITCH: Stop channel-switching with a TDLS
+ *	peer given by %NL80211_ATTR_MAC. Both peers must be on the base channel
+ *	when this command completes.
+ *
+ * @NL80211_CMD_WIPHY_REG_CHANGE: Similar to %NL80211_CMD_REG_CHANGE, but used
+ *	as an event to indicate changes for devices with wiphy-specific regdom
+ *	management.
+ *
+ * @NL80211_CMD_MAX: highest used command number
+ * @__NL80211_CMD_AFTER_LAST: internal use

+ *
+ * @NL80211_ATTR_OFFCHANNEL_TX_OK: For management frame TX, the frame may be

+ *
+ * @NL80211_ATTR_BSS_HT_OPMODE: HT operation mode (u16)
+ *
+ * @NL80211_ATTR_KEY_DEFAULT_TYPES: A nested attribute containing flags

+ *	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.

+ * 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_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: (no longer available, only
+ *	here to reserve the value for API/ABI compatibility)
+ * @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.
+ * @NL80211_FEATURE_ACTIVE_MONITOR: This driver supports an active monitor
+ *	interface. An active monitor interface behaves like a normal monitor
+ *	interface, but gets added to the driver. It ensures that incoming
+ *	unicast packets directed at the configured interface address get ACKed.
+ * @NL80211_FEATURE_AP_MODE_CHAN_WIDTH_CHANGE: This driver supports dynamic
+ *	channel bandwidth change (e.g., HT 20 <-> 40 MHz channel) during the
+ *	lifetime of a BSS.
+ * @NL80211_FEATURE_DS_PARAM_SET_IE_IN_PROBES: This device adds a DS Parameter
+ *	Set IE to probe requests.

+ *	to probe requests.
+ * @NL80211_FEATURE_QUIET: This device, in client mode, supports Quiet Period
+ *	requests sent to it by an AP.
+ * @NL80211_FEATURE_TX_POWER_INSERTION: This device is capable of inserting the
+ *	current tx power value into the TPC Report IE in the spectrum
+ *	management TPC Report action frame, and in the Radio Measurement Link
+ *	Measurement Report action frame.
+ * @NL80211_FEATURE_ACKTO_ESTIMATION: This driver supports dynamic ACK timeout
+ *	estimation (dynack). %NL80211_ATTR_WIPHY_DYN_ACK flag attribute is used
+ *	to enable dynack.
+ * @NL80211_FEATURE_STATIC_SMPS: Device supports static spatial
+ *	multiplexing powersave, ie. can turn off all but one chain
+ *	even on HT connections that should be using more chains.
+ * @NL80211_FEATURE_DYNAMIC_SMPS: Device supports dynamic spatial
+ *	multiplexing powersave, ie. can turn off all but one chain
+ *	and then wake the rest up as required after, for example,
+ *	rts/cts handshake.
+ * @NL80211_FEATURE_SUPPORTS_WMM_ADMISSION: the device supports setting up WMM
+ *	TSPEC sessions (TID aka TSID 0-7) with the %NL80211_CMD_ADD_TX_TS
+ *	command. Standard IEEE 802.11 TSPEC setup is not yet supported, it
+ *	needs to be able to handle Block-Ack agreements and other things.
+ * @NL80211_FEATURE_MAC_ON_CREATE: Device supports configuring
+ *	the vif's MAC address upon creation.
+ *	See 'macaddr' field in the vif_params (cfg80211.h).
+ * @NL80211_FEATURE_TDLS_CHANNEL_SWITCH: Driver supports channel switching when
