  31 * DOC: Station handling
  32 *
  33 * Stations are added per interface, but a special case exists with VLAN
  34 * interfaces. When a station is bound to an AP interface, it may be moved
  35 * into a VLAN identified by a VLAN interface index (%NL80211_ATTR_STA_VLAN).
  36 * The station is still assumed to belong to the AP interface it was added
  37 * to.

  42/**
  43 * DOC: Frame transmission/registration support
  44 *
  45 * Frame transmission and registration support exists to allow userspace
  46 * management entities such as wpa_supplicant react to management frames
  47 * that are not being handled by the kernel. This includes, for example,
  48 * certain classes of action frames that cannot be handled in the kernel
  49 * for various reasons.
  50 *
  51 * Frame registration is done on a per-interface basis and registrations
  52 * cannot be removed other than by closing the socket. It is possible to
  53 * specify a registration filter to register, for example, only for a
  54 * certain type of action frame. In particular with action frames, those
  55 * that userspace registers for will not be returned as unhandled by the
  56 * driver, so that the registered application has to take responsibility
  57 * for doing that.
  58 *
  59 * The type of frame that can be registered for is also dependent on the
  60 * driver and interface type. The frame types are advertised in wiphy
  61 * attributes so applications know what to expect.
  62 *
  63 * NOTE: When an interface changes type while registrations are active,
  64 *       these registrations are ignored until the interface type is
  65 *       changed again. This means that changing the interface type can
  66 *       lead to a situation that couldn't otherwise be produced, but
  67 *       any such registrations will be dormant in the sense that they
  68 *       will not be serviced, i.e. they will not receive any frames.
  69 *
  70 * Frame transmission allows userspace to send for example the required
  71 * responses to action frames. It is subject to some sanity checking,
  72 * but many frames can be transmitted. When a frame was transmitted, its
  73 * status is indicated to the sending socket.
  74 *
  75 * For more technical details, see the corresponding command descriptions
  76 * below.

  79/**
  80 * DOC: Virtual interface / concurrency capabilities
  81 *
  82 * Some devices are able to operate with virtual MACs, they can have
  83 * more than one virtual interface. The capability handling for this
  84 * is a bit complex though, as there may be a number of restrictions
  85 * on the types of concurrency that are supported.
  86 *
  87 * To start with, each device supports the interface types listed in
  88 * the %NL80211_ATTR_SUPPORTED_IFTYPES attribute, but by listing the
  89 * types there no concurrency is implied.
  90 *
  91 * Once concurrency is desired, more attributes must be observed:
  92 * To start with, since some interface types are purely managed in
  93 * software, like the AP-VLAN type in mac80211 for example, there's
  94 * an additional list of these, they can be added at any time and
  95 * are only restricted by some semantic restrictions (e.g. AP-VLAN
  96 * cannot be added without a corresponding AP interface). This list
  97 * is exported in the %NL80211_ATTR_SOFTWARE_IFTYPES attribute.
  98 *
  99 * Further, the list of supported combinations is exported. This is
 100 * in the %NL80211_ATTR_INTERFACE_COMBINATIONS attribute. Basically,
 101 * it exports a list of "groups", and at any point in time the
 102 * interfaces that are currently active must fall into any one of
 103 * the advertised groups. Within each group, there are restrictions
 104 * on the number of interfaces of different types that are supported
 105 * and also the number of different channels, along with potentially
 106 * some other restrictions. See &enum nl80211_if_combination_attrs.
 107 *
 108 * All together, these attributes define the concurrency of virtual
 109 * interfaces that a given device supports.

 208 *      regulatory domain.
 209 * @NL80211_CMD_SET_REG: Set current regulatory domain. CRDA sends this command

 211 *      domain structure which consists of %NL80211_ATTR_REG_ALPHA set to our
 212 *      current alpha2 if it found a match. It also provides
 213 *      NL80211_ATTR_REG_RULE_FLAGS, and a set of regulatory rules. Each
 214 *      regulatory rule is a nested set of attributes  given by
 215 *      %NL80211_ATTR_REG_RULE_FREQ_[START|END] and
 216 *      %NL80211_ATTR_FREQ_RANGE_MAX_BW with an attached power rule given by

 219 * @NL80211_CMD_REQ_SET_REG: ask the wireless core to set the regulatory domain
 220 *      to the specified ISO/IEC 3166-1 alpha2 country code. The core will

 222 *
 223 * @NL80211_CMD_GET_MESH_CONFIG: Get mesh networking properties for the
 224 *      interface identified by %NL80211_ATTR_IFINDEX
 225 *
 226 * @NL80211_CMD_SET_MESH_CONFIG: Set mesh networking properties for the
 227 *      interface identified by %NL80211_ATTR_IFINDEX
 228 *
 229 * @NL80211_CMD_SET_MGMT_EXTRA_IE: Set extra IEs for management frames. The
 230 *      interface is identified with %NL80211_ATTR_IFINDEX and the management
 231 *      frame subtype with %NL80211_ATTR_MGMT_SUBTYPE. The extra IE data to be
 232 *      added to the end of the specified management frame is specified with
 233 *      %NL80211_ATTR_IE. If the command succeeds, the requested data will be
 234 *      added to all specified management frames generated by
 235 *      kernel/firmware/driver.
 236 *      Note: This command has been removed and it is only reserved at this
 237 *      point to avoid re-using existing command number. The functionality this
 238 *      command was planned for has been provided with cleaner design with the
 239 *      option to specify additional IEs in NL80211_CMD_TRIGGER_SCAN,
 240 *      NL80211_CMD_AUTHENTICATE, NL80211_CMD_ASSOCIATE,
 241 *      NL80211_CMD_DEAUTHENTICATE, and NL80211_CMD_DISASSOCIATE.
 242 *
 243 * @NL80211_CMD_GET_SCAN: get scan results
 244 * @NL80211_CMD_TRIGGER_SCAN: trigger a new scan with the given parameters
 245 *      %NL80211_ATTR_TX_NO_CCK_RATE is used to decide whether to send the
 246 *      probe requests at CCK rate or not.
 247 * @NL80211_CMD_NEW_SCAN_RESULTS: scan notification (as a reply to
 248 *      NL80211_CMD_GET_SCAN and on the "scan" multicast group)
 249 * @NL80211_CMD_SCAN_ABORTED: scan was aborted, for unspecified reasons,
 250 *      partial scan results may be available
 251 *
 252 * @NL80211_CMD_START_SCHED_SCAN: start a scheduled scan at certain
 253 *      intervals, as specified by %NL80211_ATTR_SCHED_SCAN_INTERVAL.
 254 *      Like with normal scans, if SSIDs (%NL80211_ATTR_SCAN_SSIDS)
 255 *      are passed, they are used in the probe requests.  For
 256 *      broadcast, a broadcast SSID must be passed (ie. an empty
 257 *      string).  If no SSID is passed, no probe requests are sent and
 258 *      a passive scan is performed.  %NL80211_ATTR_SCAN_FREQUENCIES,
 259 *      if passed, define which channels should be scanned; if not
 260 *      passed, all channels allowed for the current regulatory domain
 261 *      are used.  Extra IEs can also be passed from the userspace by
 262 *      using the %NL80211_ATTR_IE attribute.
 263 * @NL80211_CMD_STOP_SCHED_SCAN: stop a scheduled scan.  Returns -ENOENT
 264 *      if scheduled scan is not running.
 265 * @NL80211_CMD_SCHED_SCAN_RESULTS: indicates that there are scheduled scan
 266 *      results available.
 267 * @NL80211_CMD_SCHED_SCAN_STOPPED: indicates that the scheduled scan has
 268 *      stopped.  The driver may issue this event at any time during a
 269 *      scheduled scan.  One reason for stopping the scan is if the hardware
 270 *      does not support starting an association or a normal scan while running
 271 *      a scheduled scan.  This event is also sent when the
 272 *      %NL80211_CMD_STOP_SCHED_SCAN command is received or when the interface
 273 *      is brought down while a scheduled scan was running.
 274 *
 275 * @NL80211_CMD_GET_SURVEY: get survey resuls, e.g. channel occupation
 276 *      or noise level
 277 * @NL80211_CMD_NEW_SURVEY_RESULTS: survey data notification (as a reply to
 278 *      NL80211_CMD_GET_SURVEY and on the "scan" multicast group)
 279 *
 280 * @NL80211_CMD_SET_PMKSA: Add a PMKSA cache entry, using %NL80211_ATTR_MAC
 281 *      (for the BSSID) and %NL80211_ATTR_PMKID.
 282 * @NL80211_CMD_DEL_PMKSA: Delete a PMKSA cache entry, using %NL80211_ATTR_MAC
 283 *      (for the BSSID) and %NL80211_ATTR_PMKID.
 284 * @NL80211_CMD_FLUSH_PMKSA: Flush all PMKSA cache entries.
 285 *
 286 * @NL80211_CMD_REG_CHANGE: indicates to userspace the regulatory domain
 287 *      has been changed and provides details of the request information
 288 *      that caused the change such as who initiated the regulatory request
 289 *      (%NL80211_ATTR_REG_INITIATOR), the wiphy_idx
 290 *      (%NL80211_ATTR_REG_ALPHA2) on which the request was made from if
 291 *      the initiator was %NL80211_REGDOM_SET_BY_COUNTRY_IE or
 292 *      %NL80211_REGDOM_SET_BY_DRIVER, the type of regulatory domain
 293 *      set (%NL80211_ATTR_REG_TYPE), if the type of regulatory domain is
 294 *      %NL80211_REG_TYPE_COUNTRY the alpha2 to which we have moved on
 295 *      to (%NL80211_ATTR_REG_ALPHA2).
 296 * @NL80211_CMD_REG_BEACON_HINT: indicates to userspace that an AP beacon
 297 *      has been found while world roaming thus enabling active scan or
 298 *      any mode of operation that initiates TX (beacons) on a channel
 299 *      where we would not have been able to do either before. As an example
 300 *      if you are world roaming (regulatory domain set to world or if your
 301 *      driver is using a custom world roaming regulatory domain) and while
 302 *      doing a passive scan on the 5 GHz band you find an AP there (if not
 303 *      on a DFS channel) you will now be able to actively scan for that AP
 304 *      or use AP mode on your card on that same channel. Note that this will
 305 *      never be used for channels 1-11 on the 2 GHz band as they are always
 306 *      enabled world wide. This beacon hint is only sent if your device had
 307 *      either disabled active scanning or beaconing on a channel. We send to
 308 *      userspace the wiphy on which we removed a restriction from
 309 *      (%NL80211_ATTR_WIPHY) and the channel on which this occurred
 310 *      before (%NL80211_ATTR_FREQ_BEFORE) and after (%NL80211_ATTR_FREQ_AFTER)
 311 *      the beacon hint was processed.
 312 *
 313 * @NL80211_CMD_AUTHENTICATE: authentication request and notification.
 314 *      This command is used both as a command (request to authenticate) and
 315 *      as an event on the "mlme" multicast group indicating completion of the
 316 *      authentication process.
 317 *      When used as a command, %NL80211_ATTR_IFINDEX is used to identify the
 318 *      interface. %NL80211_ATTR_MAC is used to specify PeerSTAAddress (and
 319 *      BSSID in case of station mode). %NL80211_ATTR_SSID is used to specify
 320 *      the SSID (mainly for association, but is included in authentication
 321 *      request, too, to help BSS selection. %NL80211_ATTR_WIPHY_FREQ is used
 322 *      to specify the frequence of the channel in MHz. %NL80211_ATTR_AUTH_TYPE
 323 *      is used to specify the authentication type. %NL80211_ATTR_IE is used to
 324 *      define IEs (VendorSpecificInfo, but also including RSN IE and FT IEs)
 325 *      to be added to the frame.
 326 *      When used as an event, this reports reception of an Authentication
 327 *      frame in station and IBSS modes when the local MLME processed the
 328 *      frame, i.e., it was for the local STA and was received in correct
 329 *      state. This is similar to MLME-AUTHENTICATE.confirm primitive in the
 330 *      MLME SAP interface (kernel providing MLME, userspace SME). The
 331 *      included %NL80211_ATTR_FRAME attribute contains the management frame
 332 *      (including both the header and frame body, but not FCS). This event is
 333 *      also used to indicate if the authentication attempt timed out. In that
 334 *      case the %NL80211_ATTR_FRAME attribute is replaced with a
 335 *      %NL80211_ATTR_TIMED_OUT flag (and %NL80211_ATTR_MAC to indicate which
 336 *      pending authentication timed out).
 337 * @NL80211_CMD_ASSOCIATE: association request and notification; like
 338 *      NL80211_CMD_AUTHENTICATE but for Association and Reassociation
 339 *      (similar to MLME-ASSOCIATE.request, MLME-REASSOCIATE.request,
 340 *      MLME-ASSOCIATE.confirm or MLME-REASSOCIATE.confirm primitives).
 341 * @NL80211_CMD_DEAUTHENTICATE: deauthentication request and notification; like
 342 *      NL80211_CMD_AUTHENTICATE but for Deauthentication frames (similar to
 343 *      MLME-DEAUTHENTICATION.request and MLME-DEAUTHENTICATE.indication
 344 *      primitives).
 345 * @NL80211_CMD_DISASSOCIATE: disassociation request and notification; like
 346 *      NL80211_CMD_AUTHENTICATE but for Disassociation frames (similar to
 347 *      MLME-DISASSOCIATE.request and MLME-DISASSOCIATE.indication primitives).
 348 *
 349 * @NL80211_CMD_MICHAEL_MIC_FAILURE: notification of a locally detected Michael
 350 *      MIC (part of TKIP) failure; sent on the "mlme" multicast group; the
 351 *      event includes %NL80211_ATTR_MAC to describe the source MAC address of
 352 *      the frame with invalid MIC, %NL80211_ATTR_KEY_TYPE to show the key
 353 *      type, %NL80211_ATTR_KEY_IDX to indicate the key identifier, and
 354 *      %NL80211_ATTR_KEY_SEQ to indicate the TSC value of the frame; this
 355 *      event matches with MLME-MICHAELMICFAILURE.indication() primitive
 356 *
 357 * @NL80211_CMD_JOIN_IBSS: Join a new IBSS -- given at least an SSID and a
 358 *      FREQ attribute (for the initial frequency if no peer can be found)
 359 *      and optionally a MAC (as BSSID) and FREQ_FIXED attribute if those
 360 *      should be fixed rather than automatically determined. Can only be
 361 *      executed on a network interface that is UP, and fixed BSSID/FREQ
 362 *      may be rejected. Another optional parameter is the beacon interval,
 363 *      given in the %NL80211_ATTR_BEACON_INTERVAL attribute, which if not
 364 *      given defaults to 100 TU (102.4ms).
 365 * @NL80211_CMD_LEAVE_IBSS: Leave the IBSS -- no special arguments, the IBSS is
 366 *      determined by the network interface.
 367 *
 368 * @NL80211_CMD_TESTMODE: testmode command, takes a wiphy (or ifindex) attribute
 369 *      to identify the device, and the TESTDATA blob attribute to pass through
 370 *      to the driver.
 371 *
 372 * @NL80211_CMD_CONNECT: connection request and notification; this command
 373 *      requests to connect to a specified network but without separating
 374 *      auth and assoc steps. For this, you need to specify the SSID in a
 375 *      %NL80211_ATTR_SSID attribute, and can optionally specify the association
 376 *      IEs in %NL80211_ATTR_IE, %NL80211_ATTR_AUTH_TYPE, %NL80211_ATTR_MAC,
 377 *      %NL80211_ATTR_WIPHY_FREQ, %NL80211_ATTR_CONTROL_PORT,
 378 *      %NL80211_ATTR_CONTROL_PORT_ETHERTYPE and
 379 *      %NL80211_ATTR_CONTROL_PORT_NO_ENCRYPT.
 380 *      Background scan period can optionally be
 381 *      specified in %NL80211_ATTR_BG_SCAN_PERIOD,
 382 *      if not specified default background scan configuration
 383 *      in driver is used and if period value is 0, bg scan will be disabled.
 384 *      This attribute is ignored if driver does not support roam scan.
 385 *      It is also sent as an event, with the BSSID and response IEs when the
 386 *      connection is established or failed to be established. This can be
 387 *      determined by the STATUS_CODE attribute.
 388 * @NL80211_CMD_ROAM: request that the card roam (currently not implemented),
 389 *      sent as an event when the card/driver roamed by itself.
 390 * @NL80211_CMD_DISCONNECT: drop a given connection; also used to notify
 391 *      userspace that a connection was dropped by the AP or due to other
 392 *      reasons, for this the %NL80211_ATTR_DISCONNECTED_BY_AP and
 393 *      %NL80211_ATTR_REASON_CODE attributes are used.
 394 *
 395 * @NL80211_CMD_SET_WIPHY_NETNS: Set a wiphy's netns. Note that all devices
 396 *      associated with this wiphy must be down and will follow.
 397 *
 398 * @NL80211_CMD_REMAIN_ON_CHANNEL: Request to remain awake on the specified
 399 *      channel for the specified amount of time. This can be used to do
 400 *      off-channel operations like transmit a Public Action frame and wait for
 401 *      a response while being associated to an AP on another channel.
 402 *      %NL80211_ATTR_IFINDEX is used to specify which interface (and thus
 403 *      radio) is used. %NL80211_ATTR_WIPHY_FREQ is used to specify the
 404 *      frequency for the operation and %NL80211_ATTR_WIPHY_CHANNEL_TYPE may be
 405 *      optionally used to specify additional channel parameters.
 406 *      %NL80211_ATTR_DURATION is used to specify the duration in milliseconds
 407 *      to remain on the channel. This command is also used as an event to
 408 *      notify when the requested duration starts (it may take a while for the
 409 *      driver to schedule this time due to other concurrent needs for the
 410 *      radio).
 411 *      When called, this operation returns a cookie (%NL80211_ATTR_COOKIE)
 412 *      that will be included with any events pertaining to this request;
 413 *      the cookie is also used to cancel the request.
 414 * @NL80211_CMD_CANCEL_REMAIN_ON_CHANNEL: This command can be used to cancel a
 415 *      pending remain-on-channel duration if the desired operation has been
 416 *      completed prior to expiration of the originally requested duration.
 417 *      %NL80211_ATTR_WIPHY or %NL80211_ATTR_IFINDEX is used to specify the
 418 *      radio. The %NL80211_ATTR_COOKIE attribute must be given as well to
 419 *      uniquely identify the request.
 420 *      This command is also used as an event to notify when a requested
 421 *      remain-on-channel duration has expired.
 422 *
 423 * @NL80211_CMD_SET_TX_BITRATE_MASK: Set the mask of rates to be used in TX
 424 *      rate selection. %NL80211_ATTR_IFINDEX is used to specify the interface
 425 *      and @NL80211_ATTR_TX_RATES the set of allowed rates.
 426 *
 427 * @NL80211_CMD_REGISTER_FRAME: Register for receiving certain mgmt frames
 428 *      (via @NL80211_CMD_FRAME) for processing in userspace. This command
 429 *      requires an interface index, a frame type attribute (optional for
 430 *      backward compatibility reasons, if not given assumes action frames)
 431 *      and a match attribute containing the first few bytes of the frame
 432 *      that should match, e.g. a single byte for only a category match or
 433 *      four bytes for vendor frames including the OUI. The registration
 434 *      cannot be dropped, but is removed automatically when the netlink
 435 *      socket is closed. Multiple registrations can be made.
 436 * @NL80211_CMD_REGISTER_ACTION: Alias for @NL80211_CMD_REGISTER_FRAME for
 437 *      backward compatibility
 438 * @NL80211_CMD_FRAME: Management frame TX request and RX notification. This
 439 *      command is used both as a request to transmit a management frame and
 440 *      as an event indicating reception of a frame that was not processed in
 441 *      kernel code, but is for us (i.e., which may need to be processed in a
 442 *      user space application). %NL80211_ATTR_FRAME is used to specify the
 443 *      frame contents (including header). %NL80211_ATTR_WIPHY_FREQ (and
 444 *      optionally %NL80211_ATTR_WIPHY_CHANNEL_TYPE) is used to indicate on
 445 *      which channel the frame is to be transmitted or was received. If this
 446 *      channel is not the current channel (remain-on-channel or the
 447 *      operational channel) the device will switch to the given channel and
 448 *      transmit the frame, optionally waiting for a response for the time
 449 *      specified using %NL80211_ATTR_DURATION. When called, this operation
 450 *      returns a cookie (%NL80211_ATTR_COOKIE) that will be included with the
 451 *      TX status event pertaining to the TX request.
 452 *      %NL80211_ATTR_TX_NO_CCK_RATE is used to decide whether to send the
 453 *      management frames at CCK rate or not in 2GHz band.
 454 * @NL80211_CMD_FRAME_WAIT_CANCEL: When an off-channel TX was requested, this
 455 *      command may be used with the corresponding cookie to cancel the wait
 456 *      time if it is known that it is no longer necessary.
 457 * @NL80211_CMD_ACTION: Alias for @NL80211_CMD_FRAME for backward compatibility.
 458 * @NL80211_CMD_FRAME_TX_STATUS: Report TX status of a management frame
 459 *      transmitted with %NL80211_CMD_FRAME. %NL80211_ATTR_COOKIE identifies
 460 *      the TX command and %NL80211_ATTR_FRAME includes the contents of the
 461 *      frame. %NL80211_ATTR_ACK flag is included if the recipient acknowledged
 462 *      the frame.
 463 * @NL80211_CMD_ACTION_TX_STATUS: Alias for @NL80211_CMD_FRAME_TX_STATUS for
 464 *      backward compatibility.
 465 *
 466 * @NL80211_CMD_SET_POWER_SAVE: Set powersave, using %NL80211_ATTR_PS_STATE
 467 * @NL80211_CMD_GET_POWER_SAVE: Get powersave status in %NL80211_ATTR_PS_STATE
 468 *
 469 * @NL80211_CMD_SET_CQM: Connection quality monitor configuration. This command
 470 *      is used to configure connection quality monitoring notification trigger
 471 *      levels.
 472 * @NL80211_CMD_NOTIFY_CQM: Connection quality monitor notification. This
 473 *      command is used as an event to indicate the that a trigger level was
 474 *      reached.
 475 * @NL80211_CMD_SET_CHANNEL: Set the channel (using %NL80211_ATTR_WIPHY_FREQ
 476 *      and %NL80211_ATTR_WIPHY_CHANNEL_TYPE) the given interface (identifed
 477 *      by %NL80211_ATTR_IFINDEX) shall operate on.
 478 *      In case multiple channels are supported by the device, the mechanism
 479 *      with which it switches channels is implementation-defined.
 480 *      When a monitor interface is given, it can only switch channel while
 481 *      no other interfaces are operating to avoid disturbing the operation
 482 *      of any other interfaces, and other interfaces will again take
 483 *      precedence when they are used.
 484 *
 485 * @NL80211_CMD_SET_WDS_PEER: Set the MAC address of the peer on a WDS interface.
 486 *
 487 * @NL80211_CMD_JOIN_MESH: Join a mesh. The mesh ID must be given, and initial
 488 *      mesh config parameters may be given.
 489 * @NL80211_CMD_LEAVE_MESH: Leave the mesh network -- no special arguments, the
 490 *      network is determined by the network interface.
 491 *
 492 * @NL80211_CMD_UNPROT_DEAUTHENTICATE: Unprotected deauthentication frame
 493 *      notification. This event is used to indicate that an unprotected
 494 *      deauthentication frame was dropped when MFP is in use.
 495 * @NL80211_CMD_UNPROT_DISASSOCIATE: Unprotected disassociation frame
 496 *      notification. This event is used to indicate that an unprotected
 497 *      disassociation frame was dropped when MFP is in use.
 498 *
 499 * @NL80211_CMD_NEW_PEER_CANDIDATE: Notification on the reception of a
 500 *      beacon or probe response from a compatible mesh peer.  This is only
 501 *      sent while no station information (sta_info) exists for the new peer
 502 *      candidate and when @NL80211_MESH_SETUP_USERSPACE_AUTH is set.  On
 503 *      reception of this notification, userspace may decide to create a new
 504 *      station (@NL80211_CMD_NEW_STATION).  To stop this notification from
 505 *      reoccurring, the userspace authentication daemon may want to create the
 506 *      new station with the AUTHENTICATED flag unset and maybe change it later
 507 *      depending on the authentication result.
 508 *
 509 * @NL80211_CMD_GET_WOWLAN: get Wake-on-Wireless-LAN (WoWLAN) settings.
 510 * @NL80211_CMD_SET_WOWLAN: set Wake-on-Wireless-LAN (WoWLAN) settings.
 511 *      Since wireless is more complex than wired ethernet, it supports
 512 *      various triggers. These triggers can be configured through this
 513 *      command with the %NL80211_ATTR_WOWLAN_TRIGGERS attribute. For
 514 *      more background information, see
 515 *      http://wireless.kernel.org/en/users/Documentation/WoWLAN.
 516 *
 517 * @NL80211_CMD_SET_REKEY_OFFLOAD: This command is used give the driver
 518 *      the necessary information for supporting GTK rekey offload. This
 519 *      feature is typically used during WoWLAN. The configuration data
 520 *      is contained in %NL80211_ATTR_REKEY_DATA (which is nested and
 521 *      contains the data in sub-attributes). After rekeying happened,
 522 *      this command may also be sent by the driver as an MLME event to
 523 *      inform userspace of the new replay counter.
 524 *
 525 * @NL80211_CMD_PMKSA_CANDIDATE: This is used as an event to inform userspace
 526 *      of PMKSA caching dandidates.
 527 *
 528 * @NL80211_CMD_TDLS_OPER: Perform a high-level TDLS command (e.g. link setup).
 529 * @NL80211_CMD_TDLS_MGMT: Send a TDLS management frame.
 530 *
 531 * @NL80211_CMD_UNEXPECTED_FRAME: Used by an application controlling an AP
 532 *      (or GO) interface (i.e. hostapd) to ask for unexpected frames to
 533 *      implement sending deauth to stations that send unexpected class 3
 534 *      frames. Also used as the event sent by the kernel when such a frame
 535 *      is received.
 536 *      For the event, the %NL80211_ATTR_MAC attribute carries the TA and
 537 *      other attributes like the interface index are present.
 538 *      If used as the command it must have an interface index and you can
 539 *      only unsubscribe from the event by closing the socket. Subscription
 540 *      is also for %NL80211_CMD_UNEXPECTED_4ADDR_FRAME events.
 541 *
 542 * @NL80211_CMD_UNEXPECTED_4ADDR_FRAME: Sent as an event indicating that the
 543 *      associated station identified by %NL80211_ATTR_MAC sent a 4addr frame
 544 *      and wasn't already in a 4-addr VLAN. The event will be sent similarly
 545 *      to the %NL80211_CMD_UNEXPECTED_FRAME event, to the same listener.
 546 *
 547 * @NL80211_CMD_PROBE_CLIENT: Probe an associated station on an AP interface
 548 *      by sending a null data frame to it and reporting when the frame is
 549 *      acknowleged. This is used to allow timing out inactive clients. Uses
 550 *      %NL80211_ATTR_IFINDEX and %NL80211_ATTR_MAC. The command returns a
 551 *      direct reply with an %NL80211_ATTR_COOKIE that is later used to match
 552 *      up the event with the request. The event includes the same data and
 553 *      has %NL80211_ATTR_ACK set if the frame was ACKed.
 554 *
 555 * @NL80211_CMD_REGISTER_BEACONS: Register this socket to receive beacons from
 556 *      other BSSes when any interfaces are in AP mode. This helps implement
 557 *      OLBC handling in hostapd. Beacons are reported in %NL80211_CMD_FRAME
 558 *      messages. Note that per PHY only one application may register.
 559 *
 560 * @NL80211_CMD_SET_NOACK_MAP: sets a bitmap for the individual TIDs whether
 561 *      No Acknowledgement Policy should be applied.
 562 *
 563 * @NL80211_CMD_CH_SWITCH_NOTIFY: An AP or GO may decide to switch channels
 564 *      independently of the userspace SME, send this event indicating
 565 *      %NL80211_ATTR_IFINDEX is now on %NL80211_ATTR_WIPHY_FREQ with
 566 *      %NL80211_ATTR_WIPHY_CHANNEL_TYPE.
 567 *
 568 * @NL80211_CMD_MAX: highest used command number
 569 * @__NL80211_CMD_AFTER_LAST: internal use

1051 *
1052 * @NL80211_ATTR_WIPHY_ANTENNA_TX: Bitmap of allowed antennas for transmitting.
1053 *      This can be used to mask out antennas which are not attached or should
1054 *      not be used for transmitting. If an antenna is not selected in this
1055 *      bitmap the hardware is not allowed to transmit on this antenna.
1056 *
1057 *      Each bit represents one antenna, starting with antenna 1 at the first
1058 *      bit. Depending on which antennas are selected in the bitmap, 802.11n
1059 *      drivers can derive which chainmasks to use (if all antennas belonging to
1060 *      a particular chain are disabled this chain should be disabled) and if
1061 *      a chain has diversity antennas wether diversity should be used or not.
1062 *      HT capabilities (STBC, TX Beamforming, Antenna selection) can be
1063 *      derived from the available chains after applying the antenna mask.
1064 *      Non-802.11n drivers can derive wether to use diversity or not.
1065 *      Drivers may reject configurations or RX/TX mask combinations they cannot
1066 *      support by returning -EINVAL.
1067 *
1068 * @NL80211_ATTR_WIPHY_ANTENNA_RX: Bitmap of allowed antennas for receiving.
1069 *      This can be used to mask out antennas which are not attached or should
1070 *      not be used for receiving. If an antenna is not selected in this bitmap
1071 *      the hardware should not be configured to receive on this antenna.
1072 *      For a more detailed description see @NL80211_ATTR_WIPHY_ANTENNA_TX.
1073 *
1074 * @NL80211_ATTR_WIPHY_ANTENNA_AVAIL_TX: Bitmap of antennas which are available

1079 *
1080 * @NL80211_ATTR_MCAST_RATE: Multicast tx rate (in 100 kbps) for IBSS
1081 *
1082 * @NL80211_ATTR_OFFCHANNEL_TX_OK: For management frame TX, the frame may be
1083 *      transmitted on another channel when the channel given doesn't match
1084 *      the current channel. If the current channel doesn't match and this
1085 *      flag isn't set, the frame will be rejected. This is also used as an
1086 *      nl80211 capability flag.
1087 *
1088 * @NL80211_ATTR_BSS_HT_OPMODE: HT operation mode (u16)
1089 *
1090 * @NL80211_ATTR_KEY_DEFAULT_TYPES: A nested attribute containing flags
1091 *      attributes, specifying what a key should be set as default as.
1092 *      See &enum nl80211_key_default_types.
1093 *
1094 * @NL80211_ATTR_MESH_SETUP: Optional mesh setup parameters.  These cannot be
1095 *      changed once the mesh is active.
1096 * @NL80211_ATTR_MESH_CONFIG: Mesh configuration parameters, a nested attribute
1097 *      containing attributes from &enum nl80211_meshconf_params.
1098 * @NL80211_ATTR_SUPPORT_MESH_AUTH: Currently, this means the underlying driver
1099 *      allows auth frames in a mesh to be passed to userspace for processing via
1100 *      the @NL80211_MESH_SETUP_USERSPACE_AUTH flag.
1101 * @NL80211_ATTR_STA_PLINK_STATE: The state of a mesh peer link as
1102 *      defined in &enum nl80211_plink_state. Used when userspace is
1103 *      driving the peer link management state machine.
1104 *      @NL80211_MESH_SETUP_USERSPACE_AMPE must be enabled.
1105 *
1106 * @NL80211_ATTR_WOWLAN_TRIGGERS_SUPPORTED: indicates, as part of the wiphy
1107 *      capabilities, the supported WoWLAN triggers
1108 * @NL80211_ATTR_WOWLAN_TRIGGERS: used by %NL80211_CMD_SET_WOWLAN to
1109 *      indicate which WoW triggers should be enabled. This is also
1110 *      used by %NL80211_CMD_GET_WOWLAN to get the currently enabled WoWLAN
1111 *      triggers.
1112 *
1113 * @NL80211_ATTR_SCHED_SCAN_INTERVAL: Interval between scheduled scan
1114 *      cycles, in msecs.
1115 *
1116 * @NL80211_ATTR_SCHED_SCAN_MATCH: Nested attribute with one or more
1117 *      sets of attributes to match during scheduled scans.  Only BSSs
1118 *      that match any of the sets will be reported.  These are
1119 *      pass-thru filter rules.
1120 *      For a match to succeed, the BSS must match all attributes of a
1121 *      set.  Since not every hardware supports matching all types of
1122 *      attributes, there is no guarantee that the reported BSSs are
1123 *      fully complying with the match sets and userspace needs to be
1124 *      able to ignore them by itself.
1125 *      Thus, the implementation is somewhat hardware-dependent, but
1126 *      this is only an optimization and the userspace application
1127 *      needs to handle all the non-filtered results anyway.
1128 *      If the match attributes don't make sense when combined with
1129 *      the values passed in @NL80211_ATTR_SCAN_SSIDS (eg. if an SSID
1130 *      is included in the probe request, but the match attributes
1131 *      will never let it go through), -EINVAL may be returned.
1132 *      If ommited, no filtering is done.
1133 *
1134 * @NL80211_ATTR_INTERFACE_COMBINATIONS: Nested attribute listing the supported
1135 *      interface combinations. In each nested item, it contains attributes
1136 *      defined in &enum nl80211_if_combination_attrs.
1137 * @NL80211_ATTR_SOFTWARE_IFTYPES: Nested attribute (just like
1138 *      %NL80211_ATTR_SUPPORTED_IFTYPES) containing the interface types that
1139 *      are managed in software: interfaces of these types aren't subject to
1140 *      any restrictions in their number or combinations.
1141 *
1142 * @NL80211_ATTR_REKEY_DATA: nested attribute containing the information
1143 *      necessary for GTK rekeying in the device, see &enum nl80211_rekey_data.
1144 *
1145 * @NL80211_ATTR_SCAN_SUPP_RATES: rates per to be advertised as supported in scan,
1146 *      nested array attribute containing an entry for each band, with the entry
1147 *      being a list of supported rates as defined by IEEE 802.11 7.3.2.2 but
1148 *      without the length restriction (at most %NL80211_MAX_SUPP_RATES).
1149 *
1150 * @NL80211_ATTR_HIDDEN_SSID: indicates whether SSID is to be hidden from Beacon
1151 *      and Probe Response (when response to wildcard Probe Request); see

1153 *
1154 * @NL80211_ATTR_IE_PROBE_RESP: Information element(s) for Probe Response frame.
1155 *      This is used with %NL80211_CMD_NEW_BEACON and %NL80211_CMD_SET_BEACON to
1156 *      provide extra IEs (e.g., WPS/P2P IE) into Probe Response frames when the
1157 *      driver (or firmware) replies to Probe Request frames.
1158 * @NL80211_ATTR_IE_ASSOC_RESP: Information element(s) for (Re)Association
1159 *      Response frames. This is used with %NL80211_CMD_NEW_BEACON and
1160 *      %NL80211_CMD_SET_BEACON to provide extra IEs (e.g., WPS/P2P IE) into
1161 *      (Re)Association Response frames when the driver (or firmware) replies to
1162 *      (Re)Association Request frames.
1163 *
1164 * @NL80211_ATTR_STA_WME: Nested attribute containing the wme configuration
1165 *      of the station, see &enum nl80211_sta_wme_attr.

1171 *
1172 * @NL80211_ATTR_PMKSA_CANDIDATE: Nested attribute containing the PMKSA caching
1173 *      candidate information, see &enum nl80211_pmksa_candidate_attr.
1174 *
1175 * @NL80211_ATTR_TX_NO_CCK_RATE: Indicates whether to use CCK rate or not
1176 *      for management frames transmission. In order to avoid p2p probe/action
1177 *      frames are being transmitted at CCK rate in 2GHz band, the user space
1178 *      applications use this attribute.
1179 *      This attribute is used with %NL80211_CMD_TRIGGER_SCAN and
1180 *      %NL80211_CMD_FRAME commands.
1181 *
1182 * @NL80211_ATTR_TDLS_ACTION: Low level TDLS action code (e.g. link setup
1183 *      request, link setup confirm, link teardown, etc.). Values are

1190 *      as a TDLS peer sta.
1191 * @NL80211_ATTR_TDLS_EXTERNAL_SETUP: The TDLS discovery/setup and teardown
1192 *      procedures should be performed by sending TDLS packets via
1193 *      %NL80211_CMD_TDLS_MGMT. Otherwise %NL80211_CMD_TDLS_OPER should be
1194 *      used for asking the driver to perform a TDLS operation.
1195 *
1196 * @NL80211_ATTR_DEVICE_AP_SME: This u32 attribute may be listed for devices
1197 *      that have AP support to indicate that they have the AP SME integrated
1198 *      with support for the features listed in this attribute, see
1199 *      &enum nl80211_ap_sme_features.
1200 *
1201 * @NL80211_ATTR_DONT_WAIT_FOR_ACK: Used with %NL80211_CMD_FRAME, this tells
1202 *      the driver to not wait for an acknowledgement. Note that due to this,
1203 *      it will also not give a status callback nor return a cookie. This is
1204 *      mostly useful for probe responses to save airtime.
1205 *
1206 * @NL80211_ATTR_FEATURE_FLAGS: This u32 attribute contains flags from
1207 *      &enum nl80211_feature_flags and is advertised in wiphy information.

1211 *      offloading (see &enum nl80211_probe_resp_offload_support_attr).
1212 *
1213 * @NL80211_ATTR_PROBE_RESP: Probe Response template data. Contains the entire
1214 *      probe-response frame. The DA field in the 802.11 header is zero-ed out,
1215 *      to be filled by the FW.
1216 * @NL80211_ATTR_DISABLE_HT:  Force HT capable interfaces to disable
1217 *      this feature.  Currently, only supported in mac80211 drivers.
1218 * @NL80211_ATTR_HT_CAPABILITY_MASK: Specify which bits of the
1219 *      ATTR_HT_CAPABILITY to which attention should be paid.
1220 *      Currently, only mac80211 NICs support this feature.

1222 *       MCS rates, MAX-AMSDU, HT-20-40 and HT_CAP_SGI_40
1223 *       AMPDU density and AMPDU factor.
1224 *      All values are treated as suggestions and may be ignored
1225 *      by the driver as required.  The actual values may be seen in
1226 *      the station debugfs ht_caps file.
1227 *
1228 * @NL80211_ATTR_DFS_REGION: region for regulatory rules which this country
1229 *    abides to when initiating radiation on DFS channels. A country maps
1230 *    to one DFS region.
1231 *
1232 * @NL80211_ATTR_NOACK_MAP: This u16 bitmap contains the No Ack Policy of
1233 *      up to 16 TIDs.
1234 *
1235 * @NL80211_ATTR_INACTIVITY_TIMEOUT: timeout value in seconds, this can be
1236 *      used by the drivers which has MLME in firmware and does not have support
1237 *      to report per station tx/rx activity to free up the staion entry from
1238 *      the list. This needs to be used when the driver advertises the
1239 *      capability to timeout the stations.
1240 *
1241 * @NL80211_ATTR_RX_SIGNAL_DBM: signal strength in dBm (as a 32-bit int);
1242 *      this attribute is (depending on the driver capabilities) added to
