/**
* 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.

/**
* 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

* @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_ATTR_BSSID can be used to
* specify a BSSID to scan for; if not included, the wildcard BSSID will
* be used.
* @NL80211_CMD_NEW_SCAN_RESULTS: scan notification (as a reply to

* @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 and certain number of cycles, as specified by
* %NL80211_ATTR_SCHED_SCAN_PLANS. If %NL80211_ATTR_SCHED_SCAN_PLANS is
* not specified and only %NL80211_ATTR_SCHED_SCAN_INTERVAL is specified,

* These attributes are mutually exculsive,
* i.e. NL80211_ATTR_SCHED_SCAN_INTERVAL must not be passed if
* NL80211_ATTR_SCHED_SCAN_PLANS is defined.
* If for some reason scheduled scan is aborted by the driver, all scan
* plans are canceled (including scan plans that did not start yet).
* 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. If the device supports multiple concurrent scheduled
* scans, it will allow such when the caller provides the flag attribute
* %NL80211_ATTR_SCHED_SCAN_MULTI to indicate user-space support for it.
* @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), %NL80211_ATTR_PMKID, and optionally %NL80211_ATTR_PMK
* (PMK is used for PTKSA derivation in case of FILS shared key offload) or
* using %NL80211_ATTR_SSID, %NL80211_ATTR_FILS_CACHE_ID,
* %NL80211_ATTR_PMKID, and %NL80211_ATTR_PMK in case of FILS
* authentication where %NL80211_ATTR_FILS_CACHE_ID is the identifier
* advertized by a FILS capable AP identifying the scope of PMKSA in an
* ESS.
* @NL80211_CMD_DEL_PMKSA: Delete a PMKSA cache entry, using %NL80211_ATTR_MAC
* (for the BSSID) and %NL80211_ATTR_PMKID or using %NL80211_ATTR_SSID,
* %NL80211_ATTR_FILS_CACHE_ID, and %NL80211_ATTR_PMKID in case of FILS
* authentication.
* @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 +
* %NL80211_ATTR_WIPHY_FREQ_OFFSET 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). The
* %NL80211_ATTR_PREV_BSSID attribute is used to specify whether the
* request is for the initial association to an ESS (that attribute not
* included) or for reassociation within the ESS (that attribute is
* included).
* @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_WIPHY_FREQ_OFFSET, %NL80211_ATTR_CONTROL_PORT,
* %NL80211_ATTR_CONTROL_PORT_ETHERTYPE,
* %NL80211_ATTR_CONTROL_PORT_NO_ENCRYPT,
* %NL80211_ATTR_CONTROL_PORT_OVER_NL80211, %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).
* Driver shall not modify the IEs specified through %NL80211_ATTR_IE if
* %NL80211_ATTR_MAC is included. However, if %NL80211_ATTR_MAC_HINT is
* included, these IEs through %NL80211_ATTR_IE are specified by the user
* space based on the best possible BSS selected. Thus, if the driver ends
* up selecting a different BSS, it can modify these IEs accordingly (e.g.
* userspace asks the driver to perform PMKSA caching with BSS1 and the
* driver ends up selecting BSS2 with different PMKSA cache entry; RSNIE
* has to get updated with the apt PMKID).
* %NL80211_ATTR_PREV_BSSID can be used to request a reassociation within
* the ESS in case the device is already associated and an association with
* a different BSS is desired.
* 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 %NL80211_ATTR_STATUS_CODE attribute (0 = success,
* non-zero = failure). If %NL80211_ATTR_TIMED_OUT is included in the
* event, the connection attempt failed due to not being able to initiate
* authentication/association or not receiving a response from the AP.
* Non-zero %NL80211_ATTR_STATUS_CODE value is indicated in that case as
* well to remain backwards compatible.
* @NL80211_CMD_ROAM: Notification indicating the card/driver roamed by itself.
* When a security association was established on an 802.1X network using
* fast transition, this event should be followed by an
* %NL80211_CMD_PORT_AUTHORIZED event.
* Following a %NL80211_CMD_ROAM event userspace can issue
* %NL80211_CMD_GET_SCAN in order to obtain the scan information for the
* new BSS the card/driver roamed to.
* @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.
* The %NL80211_ATTR_RECEIVE_MULTICAST flag attribute can be given if
* %NL80211_EXT_FEATURE_MULTICAST_REGISTRATIONS is available, in which
* case the registration can also be modified to include/exclude the
* flag, rather than requiring unregistration to change it.
* @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. This command is
* also sent as an event whenever the driver has completed the off-channel
* wait time.
* @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
* (no longer supported).
*
* @NL80211_CMD_SET_MULTICAST_TO_UNICAST: Configure if this AP should perform
* multicast to unicast conversion. When enabled, all multicast packets
* with ethertype ARP, IPv4 or IPv6 (possibly within an 802.1Q header)
* will be sent out to each station once with the destination (multicast)
* MAC address replaced by the station's MAC address. Note that this may
* break certain expectations of the receiver, e.g. the ability to drop
* unicast IP packets encapsulated in multicast L2 frames, or the ability
* to not send destination unreachable messages in such cases.
* This can only be toggled per BSS. Configure this on an interface of
* type %NL80211_IFTYPE_AP. It applies to all its VLAN interfaces
* (%NL80211_IFTYPE_AP_VLAN), except for those in 4addr (WDS) mode.
* If %NL80211_ATTR_MULTICAST_TO_UNICAST_ENABLED is not present with this
* command, the feature is disabled.
*
* @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
* https://wireless.wiki.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
* 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
