 54  * DOC: Station handling
 55  *
 56  * Stations are added per interface, but a special case exists with VLAN
 57  * interfaces. When a station is bound to an AP interface, it may be moved
 58  * into a VLAN identified by a VLAN interface index (%NL80211_ATTR_STA_VLAN).
 59  * The station is still assumed to belong to the AP interface it was added
 60  * to.
 61  *
 62  * Station handling varies per interface type and depending on the driver's
 63  * capabilities.
 64  *
 65  * For drivers supporting TDLS with external setup (WIPHY_FLAG_SUPPORTS_TDLS
 66  * and WIPHY_FLAG_TDLS_EXTERNAL_SETUP), the station lifetime is as follows:
 67  *  - a setup station entry is added, not yet authorized, without any rate
 68  *    or capability information, this just exists to avoid race conditions
 69  *  - when the TDLS setup is done, a single NL80211_CMD_SET_STATION is valid
 70  *    to add rate and capability information to the station and at the same
 71  *    time mark it authorized.
 72  *  - %NL80211_TDLS_ENABLE_LINK is then used
 73  *  - after this, the only valid operation is to remove it by tearing down
 74  *    the TDLS link (%NL80211_TDLS_DISABLE_LINK)

 80  * DOC: Frame transmission/registration support
 81  *
 82  * Frame transmission and registration support exists to allow userspace
 83  * management entities such as wpa_supplicant react to management frames
 84  * that are not being handled by the kernel. This includes, for example,
 85  * certain classes of action frames that cannot be handled in the kernel
 86  * for various reasons.
 87  *
 88  * Frame registration is done on a per-interface basis and registrations
 89  * cannot be removed other than by closing the socket. It is possible to
 90  * specify a registration filter to register, for example, only for a
 91  * certain type of action frame. In particular with action frames, those
 92  * that userspace registers for will not be returned as unhandled by the
 93  * driver, so that the registered application has to take responsibility
 94  * for doing that.
 95  *
 96  * The type of frame that can be registered for is also dependent on the
 97  * driver and interface type. The frame types are advertised in wiphy
 98  * attributes so applications know what to expect.
 99  *
100  * NOTE: When an interface changes type while registrations are active,
101  *       these registrations are ignored until the interface type is
102  *       changed again. This means that changing the interface type can
103  *       lead to a situation that couldn't otherwise be produced, but
104  *       any such registrations will be dormant in the sense that they
105  *       will not be serviced, i.e. they will not receive any frames.
106  *
107  * Frame transmission allows userspace to send for example the required
108  * responses to action frames. It is subject to some sanity checking,
109  * but many frames can be transmitted. When a frame was transmitted, its
110  * status is indicated to the sending socket.
111  *
112  * For more technical details, see the corresponding command descriptions
113  * below.

117  * DOC: Virtual interface / concurrency capabilities
118  *
119  * Some devices are able to operate with virtual MACs, they can have
120  * more than one virtual interface. The capability handling for this
121  * is a bit complex though, as there may be a number of restrictions
122  * on the types of concurrency that are supported.
123  *
124  * To start with, each device supports the interface types listed in
125  * the %NL80211_ATTR_SUPPORTED_IFTYPES attribute, but by listing the
126  * types there no concurrency is implied.
127  *
128  * Once concurrency is desired, more attributes must be observed:
129  * To start with, since some interface types are purely managed in
130  * software, like the AP-VLAN type in mac80211 for example, there's
131  * an additional list of these, they can be added at any time and
132  * are only restricted by some semantic restrictions (e.g. AP-VLAN
133  * cannot be added without a corresponding AP interface). This list
134  * is exported in the %NL80211_ATTR_SOFTWARE_IFTYPES attribute.
135  *
136  * Further, the list of supported combinations is exported. This is
137  * in the %NL80211_ATTR_INTERFACE_COMBINATIONS attribute. Basically,
138  * it exports a list of "groups", and at any point in time the
139  * interfaces that are currently active must fall into any one of
140  * the advertised groups. Within each group, there are restrictions
141  * on the number of interfaces of different types that are supported
142  * and also the number of different channels, along with potentially
143  * some other restrictions. See &enum nl80211_if_combination_attrs.
144  *
145  * All together, these attributes define the concurrency of virtual
146  * interfaces that a given device supports.

150  * DOC: packet coalesce support
151  *
152  * In most cases, host that receives IPv4 and IPv6 multicast/broadcast
153  * packets does not do anything with these packets. Therefore the
154  * reception of these unwanted packets causes unnecessary processing
155  * and power consumption.
156  *
157  * Packet coalesce feature helps to reduce number of received interrupts
158  * to host by buffering these packets in firmware/hardware for some
159  * predefined time. Received interrupt will be generated when one of the
160  * following events occur.
161  * a) Expiration of hardware timer whose expiration time is set to maximum
162  * coalescing delay of matching coalesce rule.
163  * b) Coalescing buffer in hardware reaches it's limit.
164  * c) Packet doesn't match any of the configured coalesce rules.
165  *
166  * User needs to configure following parameters for creating a coalesce
167  * rule.
168  * a) Maximum coalescing delay
169  * b) List of packet patterns which needs to be matched
170  * c) Condition for coalescence. pattern 'match' or 'no match'
171  * Multiple such rules can be created.

341  *      Like with normal scans, if SSIDs (%NL80211_ATTR_SCAN_SSIDS)
342  *      are passed, they are used in the probe requests.  For
343  *      broadcast, a broadcast SSID must be passed (ie. an empty
344  *      string).  If no SSID is passed, no probe requests are sent and
345  *      a passive scan is performed.  %NL80211_ATTR_SCAN_FREQUENCIES,
346  *      if passed, define which channels should be scanned; if not
347  *      passed, all channels allowed for the current regulatory domain
348  *      are used.  Extra IEs can also be passed from the userspace by
349  *      using the %NL80211_ATTR_IE attribute.  The first cycle of the
350  *      scheduled scan can be delayed by %NL80211_ATTR_SCHED_SCAN_DELAY
351  *      is supplied.
352  * @NL80211_CMD_STOP_SCHED_SCAN: stop a scheduled scan. Returns -ENOENT if
353  *      scheduled scan is not running. The caller may assume that as soon
354  *      as the call returns, it is safe to start a new scheduled scan again.
355  * @NL80211_CMD_SCHED_SCAN_RESULTS: indicates that there are scheduled scan
356  *      results available.
357  * @NL80211_CMD_SCHED_SCAN_STOPPED: indicates that the scheduled scan has
358  *      stopped.  The driver may issue this event at any time during a
359  *      scheduled scan.  One reason for stopping the scan is if the hardware
360  *      does not support starting an association or a normal scan while running
361  *      a scheduled scan.  This event is also sent when the
362  *      %NL80211_CMD_STOP_SCHED_SCAN command is received or when the interface
363  *      is brought down while a scheduled scan was running.
364  *
365  * @NL80211_CMD_GET_SURVEY: get survey resuls, e.g. channel occupation
366  *      or noise level
367  * @NL80211_CMD_NEW_SURVEY_RESULTS: survey data notification (as a reply to
368  *      NL80211_CMD_GET_SURVEY and on the "scan" multicast group)
369  *
370  * @NL80211_CMD_SET_PMKSA: Add a PMKSA cache entry, using %NL80211_ATTR_MAC
371  *      (for the BSSID) and %NL80211_ATTR_PMKID.
372  * @NL80211_CMD_DEL_PMKSA: Delete a PMKSA cache entry, using %NL80211_ATTR_MAC
373  *      (for the BSSID) and %NL80211_ATTR_PMKID.
374  * @NL80211_CMD_FLUSH_PMKSA: Flush all PMKSA cache entries.
375  *
376  * @NL80211_CMD_REG_CHANGE: indicates to userspace the regulatory domain
377  *      has been changed and provides details of the request information
378  *      that caused the change such as who initiated the regulatory request
379  *      (%NL80211_ATTR_REG_INITIATOR), the wiphy_idx
380  *      (%NL80211_ATTR_REG_ALPHA2) on which the request was made from if
381  *      the initiator was %NL80211_REGDOM_SET_BY_COUNTRY_IE or
382  *      %NL80211_REGDOM_SET_BY_DRIVER, the type of regulatory domain
383  *      set (%NL80211_ATTR_REG_TYPE), if the type of regulatory domain is
384  *      %NL80211_REG_TYPE_COUNTRY the alpha2 to which we have moved on
385  *      to (%NL80211_ATTR_REG_ALPHA2).
386  * @NL80211_CMD_REG_BEACON_HINT: indicates to userspace that an AP beacon
387  *      has been found while world roaming thus enabling active scan or
388  *      any mode of operation that initiates TX (beacons) on a channel
389  *      where we would not have been able to do either before. As an example
390  *      if you are world roaming (regulatory domain set to world or if your
391  *      driver is using a custom world roaming regulatory domain) and while
392  *      doing a passive scan on the 5 GHz band you find an AP there (if not
393  *      on a DFS channel) you will now be able to actively scan for that AP
394  *      or use AP mode on your card on that same channel. Note that this will
395  *      never be used for channels 1-11 on the 2 GHz band as they are always
396  *      enabled world wide. This beacon hint is only sent if your device had
397  *      either disabled active scanning or beaconing on a channel. We send to
398  *      userspace the wiphy on which we removed a restriction from
399  *      (%NL80211_ATTR_WIPHY) and the channel on which this occurred
400  *      before (%NL80211_ATTR_FREQ_BEFORE) and after (%NL80211_ATTR_FREQ_AFTER)
401  *      the beacon hint was processed.
402  *
403  * @NL80211_CMD_AUTHENTICATE: authentication request and notification.
404  *      This command is used both as a command (request to authenticate) and
405  *      as an event on the "mlme" multicast group indicating completion of the
406  *      authentication process.
407  *      When used as a command, %NL80211_ATTR_IFINDEX is used to identify the
408  *      interface. %NL80211_ATTR_MAC is used to specify PeerSTAAddress (and
409  *      BSSID in case of station mode). %NL80211_ATTR_SSID is used to specify
410  *      the SSID (mainly for association, but is included in authentication
411  *      request, too, to help BSS selection. %NL80211_ATTR_WIPHY_FREQ is used
412  *      to specify the frequence of the channel in MHz. %NL80211_ATTR_AUTH_TYPE
413  *      is used to specify the authentication type. %NL80211_ATTR_IE is used to
414  *      define IEs (VendorSpecificInfo, but also including RSN IE and FT IEs)
415  *      to be added to the frame.
416  *      When used as an event, this reports reception of an Authentication
417  *      frame in station and IBSS modes when the local MLME processed the
418  *      frame, i.e., it was for the local STA and was received in correct
419  *      state. This is similar to MLME-AUTHENTICATE.confirm primitive in the
420  *      MLME SAP interface (kernel providing MLME, userspace SME). The
421  *      included %NL80211_ATTR_FRAME attribute contains the management frame
422  *      (including both the header and frame body, but not FCS). This event is
423  *      also used to indicate if the authentication attempt timed out. In that
424  *      case the %NL80211_ATTR_FRAME attribute is replaced with a
425  *      %NL80211_ATTR_TIMED_OUT flag (and %NL80211_ATTR_MAC to indicate which
426  *      pending authentication timed out).
427  * @NL80211_CMD_ASSOCIATE: association request and notification; like
428  *      NL80211_CMD_AUTHENTICATE but for Association and Reassociation
429  *      (similar to MLME-ASSOCIATE.request, MLME-REASSOCIATE.request,
430  *      MLME-ASSOCIATE.confirm or MLME-REASSOCIATE.confirm primitives).
431  * @NL80211_CMD_DEAUTHENTICATE: deauthentication request and notification; like
432  *      NL80211_CMD_AUTHENTICATE but for Deauthentication frames (similar to
433  *      MLME-DEAUTHENTICATION.request and MLME-DEAUTHENTICATE.indication
434  *      primitives).
435  * @NL80211_CMD_DISASSOCIATE: disassociation request and notification; like
436  *      NL80211_CMD_AUTHENTICATE but for Disassociation frames (similar to
437  *      MLME-DISASSOCIATE.request and MLME-DISASSOCIATE.indication primitives).
438  *
439  * @NL80211_CMD_MICHAEL_MIC_FAILURE: notification of a locally detected Michael
440  *      MIC (part of TKIP) failure; sent on the "mlme" multicast group; the
441  *      event includes %NL80211_ATTR_MAC to describe the source MAC address of
442  *      the frame with invalid MIC, %NL80211_ATTR_KEY_TYPE to show the key
443  *      type, %NL80211_ATTR_KEY_IDX to indicate the key identifier, and
444  *      %NL80211_ATTR_KEY_SEQ to indicate the TSC value of the frame; this
445  *      event matches with MLME-MICHAELMICFAILURE.indication() primitive
446  *
447  * @NL80211_CMD_JOIN_IBSS: Join a new IBSS -- given at least an SSID and a
448  *      FREQ attribute (for the initial frequency if no peer can be found)
449  *      and optionally a MAC (as BSSID) and FREQ_FIXED attribute if those
450  *      should be fixed rather than automatically determined. Can only be
451  *      executed on a network interface that is UP, and fixed BSSID/FREQ
452  *      may be rejected. Another optional parameter is the beacon interval,
453  *      given in the %NL80211_ATTR_BEACON_INTERVAL attribute, which if not
454  *      given defaults to 100 TU (102.4ms).
455  * @NL80211_CMD_LEAVE_IBSS: Leave the IBSS -- no special arguments, the IBSS is
456  *      determined by the network interface.
457  *
458  * @NL80211_CMD_TESTMODE: testmode command, takes a wiphy (or ifindex) attribute
459  *      to identify the device, and the TESTDATA blob attribute to pass through
460  *      to the driver.
461  *
462  * @NL80211_CMD_CONNECT: connection request and notification; this command
463  *      requests to connect to a specified network but without separating
464  *      auth and assoc steps. For this, you need to specify the SSID in a
465  *      %NL80211_ATTR_SSID attribute, and can optionally specify the association
466  *      IEs in %NL80211_ATTR_IE, %NL80211_ATTR_AUTH_TYPE, %NL80211_ATTR_USE_MFP,
467  *      %NL80211_ATTR_MAC, %NL80211_ATTR_WIPHY_FREQ, %NL80211_ATTR_CONTROL_PORT,
468  *      %NL80211_ATTR_CONTROL_PORT_ETHERTYPE,
469  *      %NL80211_ATTR_CONTROL_PORT_NO_ENCRYPT, %NL80211_ATTR_MAC_HINT, and
470  *      %NL80211_ATTR_WIPHY_FREQ_HINT.
471  *      If included, %NL80211_ATTR_MAC and %NL80211_ATTR_WIPHY_FREQ are
472  *      restrictions on BSS selection, i.e., they effectively prevent roaming
473  *      within the ESS. %NL80211_ATTR_MAC_HINT and %NL80211_ATTR_WIPHY_FREQ_HINT
474  *      can be included to provide a recommendation of the initial BSS while
475  *      allowing the driver to roam to other BSSes within the ESS and also to
476  *      ignore this recommendation if the indicated BSS is not ideal. Only one
477  *      set of BSSID,frequency parameters is used (i.e., either the enforcing
478  *      %NL80211_ATTR_MAC,%NL80211_ATTR_WIPHY_FREQ or the less strict
479  *      %NL80211_ATTR_MAC_HINT and %NL80211_ATTR_WIPHY_FREQ_HINT).
480  *      Background scan period can optionally be
481  *      specified in %NL80211_ATTR_BG_SCAN_PERIOD,
482  *      if not specified default background scan configuration
483  *      in driver is used and if period value is 0, bg scan will be disabled.
484  *      This attribute is ignored if driver does not support roam scan.
485  *      It is also sent as an event, with the BSSID and response IEs when the
486  *      connection is established or failed to be established. This can be
487  *      determined by the STATUS_CODE attribute.
488  * @NL80211_CMD_ROAM: request that the card roam (currently not implemented),
489  *      sent as an event when the card/driver roamed by itself.
490  * @NL80211_CMD_DISCONNECT: drop a given connection; also used to notify
491  *      userspace that a connection was dropped by the AP or due to other
492  *      reasons, for this the %NL80211_ATTR_DISCONNECTED_BY_AP and
493  *      %NL80211_ATTR_REASON_CODE attributes are used.
494  *
495  * @NL80211_CMD_SET_WIPHY_NETNS: Set a wiphy's netns. Note that all devices
496  *      associated with this wiphy must be down and will follow.
497  *
498  * @NL80211_CMD_REMAIN_ON_CHANNEL: Request to remain awake on the specified
499  *      channel for the specified amount of time. This can be used to do
500  *      off-channel operations like transmit a Public Action frame and wait for
501  *      a response while being associated to an AP on another channel.
502  *      %NL80211_ATTR_IFINDEX is used to specify which interface (and thus
503  *      radio) is used. %NL80211_ATTR_WIPHY_FREQ is used to specify the
504  *      frequency for the operation.
505  *      %NL80211_ATTR_DURATION is used to specify the duration in milliseconds
506  *      to remain on the channel. This command is also used as an event to
507  *      notify when the requested duration starts (it may take a while for the
508  *      driver to schedule this time due to other concurrent needs for the
509  *      radio).
510  *      When called, this operation returns a cookie (%NL80211_ATTR_COOKIE)
511  *      that will be included with any events pertaining to this request;
512  *      the cookie is also used to cancel the request.
513  * @NL80211_CMD_CANCEL_REMAIN_ON_CHANNEL: This command can be used to cancel a
514  *      pending remain-on-channel duration if the desired operation has been
515  *      completed prior to expiration of the originally requested duration.
516  *      %NL80211_ATTR_WIPHY or %NL80211_ATTR_IFINDEX is used to specify the
517  *      radio. The %NL80211_ATTR_COOKIE attribute must be given as well to
518  *      uniquely identify the request.
519  *      This command is also used as an event to notify when a requested
520  *      remain-on-channel duration has expired.
521  *
522  * @NL80211_CMD_SET_TX_BITRATE_MASK: Set the mask of rates to be used in TX
523  *      rate selection. %NL80211_ATTR_IFINDEX is used to specify the interface
524  *      and @NL80211_ATTR_TX_RATES the set of allowed rates.
525  *
526  * @NL80211_CMD_REGISTER_FRAME: Register for receiving certain mgmt frames
527  *      (via @NL80211_CMD_FRAME) for processing in userspace. This command
528  *      requires an interface index, a frame type attribute (optional for
529  *      backward compatibility reasons, if not given assumes action frames)
530  *      and a match attribute containing the first few bytes of the frame
531  *      that should match, e.g. a single byte for only a category match or
532  *      four bytes for vendor frames including the OUI. The registration
533  *      cannot be dropped, but is removed automatically when the netlink
534  *      socket is closed. Multiple registrations can be made.
535  * @NL80211_CMD_REGISTER_ACTION: Alias for @NL80211_CMD_REGISTER_FRAME for
536  *      backward compatibility
537  * @NL80211_CMD_FRAME: Management frame TX request and RX notification. This
538  *      command is used both as a request to transmit a management frame and
539  *      as an event indicating reception of a frame that was not processed in
540  *      kernel code, but is for us (i.e., which may need to be processed in a
541  *      user space application). %NL80211_ATTR_FRAME is used to specify the
542  *      frame contents (including header). %NL80211_ATTR_WIPHY_FREQ is used
543  *      to indicate on which channel the frame is to be transmitted or was
544  *      received. If this channel is not the current channel (remain-on-channel
545  *      or the operational channel) the device will switch to the given channel
546  *      and transmit the frame, optionally waiting for a response for the time
547  *      specified using %NL80211_ATTR_DURATION. When called, this operation
548  *      returns a cookie (%NL80211_ATTR_COOKIE) that will be included with the
549  *      TX status event pertaining to the TX request.
550  *      %NL80211_ATTR_TX_NO_CCK_RATE is used to decide whether to send the
551  *      management frames at CCK rate or not in 2GHz band.
552  *      %NL80211_ATTR_CSA_C_OFFSETS_TX is an array of offsets to CSA
553  *      counters which will be updated to the current value. This attribute
554  *      is used during CSA period.
555  * @NL80211_CMD_FRAME_WAIT_CANCEL: When an off-channel TX was requested, this
556  *      command may be used with the corresponding cookie to cancel the wait
557  *      time if it is known that it is no longer necessary.
558  * @NL80211_CMD_ACTION: Alias for @NL80211_CMD_FRAME for backward compatibility.
559  * @NL80211_CMD_FRAME_TX_STATUS: Report TX status of a management frame
560  *      transmitted with %NL80211_CMD_FRAME. %NL80211_ATTR_COOKIE identifies
561  *      the TX command and %NL80211_ATTR_FRAME includes the contents of the
562  *      frame. %NL80211_ATTR_ACK flag is included if the recipient acknowledged
563  *      the frame.
564  * @NL80211_CMD_ACTION_TX_STATUS: Alias for @NL80211_CMD_FRAME_TX_STATUS for
565  *      backward compatibility.
566  *
567  * @NL80211_CMD_SET_POWER_SAVE: Set powersave, using %NL80211_ATTR_PS_STATE
568  * @NL80211_CMD_GET_POWER_SAVE: Get powersave status in %NL80211_ATTR_PS_STATE
569  *
570  * @NL80211_CMD_SET_CQM: Connection quality monitor configuration. This command
571  *      is used to configure connection quality monitoring notification trigger
572  *      levels.
573  * @NL80211_CMD_NOTIFY_CQM: Connection quality monitor notification. This
574  *      command is used as an event to indicate the that a trigger level was
575  *      reached.
576  * @NL80211_CMD_SET_CHANNEL: Set the channel (using %NL80211_ATTR_WIPHY_FREQ
577  *      and the attributes determining channel width) the given interface
578  *      (identifed by %NL80211_ATTR_IFINDEX) shall operate on.
579  *      In case multiple channels are supported by the device, the mechanism
580  *      with which it switches channels is implementation-defined.
581  *      When a monitor interface is given, it can only switch channel while
582  *      no other interfaces are operating to avoid disturbing the operation
583  *      of any other interfaces, and other interfaces will again take
584  *      precedence when they are used.
585  *
586  * @NL80211_CMD_SET_WDS_PEER: Set the MAC address of the peer on a WDS interface.
587  *
588  * @NL80211_CMD_JOIN_MESH: Join a mesh. The mesh ID must be given, and initial
589  *      mesh config parameters may be given.
590  * @NL80211_CMD_LEAVE_MESH: Leave the mesh network -- no special arguments, the
591  *      network is determined by the network interface.
592  *
593  * @NL80211_CMD_UNPROT_DEAUTHENTICATE: Unprotected deauthentication frame
594  *      notification. This event is used to indicate that an unprotected
595  *      deauthentication frame was dropped when MFP is in use.
596  * @NL80211_CMD_UNPROT_DISASSOCIATE: Unprotected disassociation frame
597  *      notification. This event is used to indicate that an unprotected
598  *      disassociation frame was dropped when MFP is in use.
599  *
600  * @NL80211_CMD_NEW_PEER_CANDIDATE: Notification on the reception of a
601  *      beacon or probe response from a compatible mesh peer.  This is only
602  *      sent while no station information (sta_info) exists for the new peer
603  *      candidate and when @NL80211_MESH_SETUP_USERSPACE_AUTH,
604  *      @NL80211_MESH_SETUP_USERSPACE_AMPE, or
605  *      @NL80211_MESH_SETUP_USERSPACE_MPM is set.  On reception of this
606  *      notification, userspace may decide to create a new station
607  *      (@NL80211_CMD_NEW_STATION).  To stop this notification from
608  *      reoccurring, the userspace authentication daemon may want to create the
609  *      new station with the AUTHENTICATED flag unset and maybe change it later
610  *      depending on the authentication result.
611  *
612  * @NL80211_CMD_GET_WOWLAN: get Wake-on-Wireless-LAN (WoWLAN) settings.
613  * @NL80211_CMD_SET_WOWLAN: set Wake-on-Wireless-LAN (WoWLAN) settings.
614  *      Since wireless is more complex than wired ethernet, it supports
615  *      various triggers. These triggers can be configured through this
616  *      command with the %NL80211_ATTR_WOWLAN_TRIGGERS attribute. For
617  *      more background information, see
618  *      http://wireless.kernel.org/en/users/Documentation/WoWLAN.
619  *      The @NL80211_CMD_SET_WOWLAN command can also be used as a notification
620  *      from the driver reporting the wakeup reason. In this case, the
621  *      @NL80211_ATTR_WOWLAN_TRIGGERS attribute will contain the reason
622  *      for the wakeup, if it was caused by wireless. If it is not present
623  *      in the wakeup notification, the wireless device didn't cause the
624  *      wakeup but reports that it was woken up.
625  *
626  * @NL80211_CMD_SET_REKEY_OFFLOAD: This command is used give the driver
627  *      the necessary information for supporting GTK rekey offload. This
628  *      feature is typically used during WoWLAN. The configuration data
629  *      is contained in %NL80211_ATTR_REKEY_DATA (which is nested and
630  *      contains the data in sub-attributes). After rekeying happened,
631  *      this command may also be sent by the driver as an MLME event to
632  *      inform userspace of the new replay counter.
633  *
634  * @NL80211_CMD_PMKSA_CANDIDATE: This is used as an event to inform userspace
635  *      of PMKSA caching dandidates.
636  *
637  * @NL80211_CMD_TDLS_OPER: Perform a high-level TDLS command (e.g. link setup).
638  *      In addition, this can be used as an event to request userspace to take
639  *      actions on TDLS links (set up a new link or tear down an existing one).
640  *      In such events, %NL80211_ATTR_TDLS_OPERATION indicates the requested
641  *      operation, %NL80211_ATTR_MAC contains the peer MAC address, and
642  *      %NL80211_ATTR_REASON_CODE the reason code to be used (only with
643  *      %NL80211_TDLS_TEARDOWN).
644  * @NL80211_CMD_TDLS_MGMT: Send a TDLS management frame. The
645  *      %NL80211_ATTR_TDLS_ACTION attribute determines the type of frame to be
646  *      sent. Public Action codes (802.11-2012 8.1.5.1) will be sent as
647  *      802.11 management frames, while TDLS action codes (802.11-2012
648  *      8.5.13.1) will be encapsulated and sent as data frames. The currently
649  *      supported Public Action code is %WLAN_PUB_ACTION_TDLS_DISCOVER_RES
650  *      and the currently supported TDLS actions codes are given in
651  *      &enum ieee80211_tdls_actioncode.
652  *
653  * @NL80211_CMD_UNEXPECTED_FRAME: Used by an application controlling an AP
654  *      (or GO) interface (i.e. hostapd) to ask for unexpected frames to
655  *      implement sending deauth to stations that send unexpected class 3
656  *      frames. Also used as the event sent by the kernel when such a frame
657  *      is received.
658  *      For the event, the %NL80211_ATTR_MAC attribute carries the TA and
659  *      other attributes like the interface index are present.
660  *      If used as the command it must have an interface index and you can
661  *      only unsubscribe from the event by closing the socket. Subscription
662  *      is also for %NL80211_CMD_UNEXPECTED_4ADDR_FRAME events.
663  *
664  * @NL80211_CMD_UNEXPECTED_4ADDR_FRAME: Sent as an event indicating that the
665  *      associated station identified by %NL80211_ATTR_MAC sent a 4addr frame
666  *      and wasn't already in a 4-addr VLAN. The event will be sent similarly
667  *      to the %NL80211_CMD_UNEXPECTED_FRAME event, to the same listener.
668  *
669  * @NL80211_CMD_PROBE_CLIENT: Probe an associated station on an AP interface
670  *      by sending a null data frame to it and reporting when the frame is
671  *      acknowleged. This is used to allow timing out inactive clients. Uses
672  *      %NL80211_ATTR_IFINDEX and %NL80211_ATTR_MAC. The command returns a
673  *      direct reply with an %NL80211_ATTR_COOKIE that is later used to match
674  *      up the event with the request. The event includes the same data and
675  *      has %NL80211_ATTR_ACK set if the frame was ACKed.
676  *
677  * @NL80211_CMD_REGISTER_BEACONS: Register this socket to receive beacons from
678  *      other BSSes when any interfaces are in AP mode. This helps implement
679  *      OLBC handling in hostapd. Beacons are reported in %NL80211_CMD_FRAME
680  *      messages. Note that per PHY only one application may register.
681  *
682  * @NL80211_CMD_SET_NOACK_MAP: sets a bitmap for the individual TIDs whether
683  *      No Acknowledgement Policy should be applied.
684  *
685  * @NL80211_CMD_CH_SWITCH_NOTIFY: An AP or GO may decide to switch channels
686  *      independently of the userspace SME, send this event indicating
687  *      %NL80211_ATTR_IFINDEX is now on %NL80211_ATTR_WIPHY_FREQ and the
688  *      attributes determining channel width.  This indication may also be
689  *      sent when a remotely-initiated switch (e.g., when a STA receives a CSA
690  *      from the remote AP) is completed;
691  *
692  * @NL80211_CMD_CH_SWITCH_STARTED_NOTIFY: Notify that a channel switch
693  *      has been started on an interface, regardless of the initiator
694  *      (ie. whether it was requested from a remote device or
695  *      initiated on our own).  It indicates that
696  *      %NL80211_ATTR_IFINDEX will be on %NL80211_ATTR_WIPHY_FREQ
697  *      after %NL80211_ATTR_CH_SWITCH_COUNT TBTT's.  The userspace may
698  *      decide to react to this indication by requesting other
699  *      interfaces to change channel as well.
700  *
701  * @NL80211_CMD_START_P2P_DEVICE: Start the given P2P Device, identified by
702  *      its %NL80211_ATTR_WDEV identifier. It must have been created with
703  *      %NL80211_CMD_NEW_INTERFACE previously. After it has been started, the
704  *      P2P Device can be used for P2P operations, e.g. remain-on-channel and
705  *      public action frame TX.
706  * @NL80211_CMD_STOP_P2P_DEVICE: Stop the given P2P Device, identified by
707  *      its %NL80211_ATTR_WDEV identifier.
708  *
709  * @NL80211_CMD_CONN_FAILED: connection request to an AP failed; used to
710  *      notify userspace that AP has rejected the connection request from a
711  *      station, due to particular reason. %NL80211_ATTR_CONN_FAILED_REASON
712  *      is used for this.
713  *
714  * @NL80211_CMD_SET_MCAST_RATE: Change the rate used to send multicast frames
715  *      for IBSS or MESH vif.
716  *
717  * @NL80211_CMD_SET_MAC_ACL: sets ACL for MAC address based access control.
718  *      This is to be used with the drivers advertising the support of MAC
719  *      address based access control. List of MAC addresses is passed in
720  *      %NL80211_ATTR_MAC_ADDRS and ACL policy is passed in
721  *      %NL80211_ATTR_ACL_POLICY. Driver will enable ACL with this list, if it
722  *      is not already done. The new list will replace any existing list. Driver
723  *      will clear its ACL when the list of MAC addresses passed is empty. This
724  *      command is used in AP/P2P GO mode. Driver has to make sure to clear its
725  *      ACL list during %NL80211_CMD_STOP_AP.
726  *
727  * @NL80211_CMD_RADAR_DETECT: Start a Channel availability check (CAC). Once
728  *      a radar is detected or the channel availability scan (CAC) has finished
729  *      or was aborted, or a radar was detected, usermode will be notified with
730  *      this event. This command is also used to notify userspace about radars
731  *      while operating on this channel.
732  *      %NL80211_ATTR_RADAR_EVENT is used to inform about the type of the
733  *      event.
734  *
735  * @NL80211_CMD_GET_PROTOCOL_FEATURES: Get global nl80211 protocol features,
736  *      i.e. features for the nl80211 protocol rather than device features.
737  *      Returns the features in the %NL80211_ATTR_PROTOCOL_FEATURES bitmap.
738  *
739  * @NL80211_CMD_UPDATE_FT_IES: Pass down the most up-to-date Fast Transition
740  *      Information Element to the WLAN driver
741  *
742  * @NL80211_CMD_FT_EVENT: Send a Fast transition event from the WLAN driver
743  *      to the supplicant. This will carry the target AP's MAC address along
744  *      with the relevant Information Elements. This event is used to report
745  *      received FT IEs (MDIE, FTIE, RSN IE, TIE, RICIE).
746  *
747  * @NL80211_CMD_CRIT_PROTOCOL_START: Indicates user-space will start running
748  *      a critical protocol that needs more reliability in the connection to
749  *      complete.
750  *
751  * @NL80211_CMD_CRIT_PROTOCOL_STOP: Indicates the connection reliability can
752  *      return back to normal.
753  *
754  * @NL80211_CMD_GET_COALESCE: Get currently supported coalesce rules.
755  * @NL80211_CMD_SET_COALESCE: Configure coalesce rules or clear existing rules.
756  *
757  * @NL80211_CMD_CHANNEL_SWITCH: Perform a channel switch by announcing the
758  *      the new channel information (Channel Switch Announcement - CSA)
759  *      in the beacon for some time (as defined in the
760  *      %NL80211_ATTR_CH_SWITCH_COUNT parameter) and then change to the
761  *      new channel. Userspace provides the new channel information (using
762  *      %NL80211_ATTR_WIPHY_FREQ and the attributes determining channel
763  *      width). %NL80211_ATTR_CH_SWITCH_BLOCK_TX may be supplied to inform
764  *      other station that transmission must be blocked until the channel
765  *      switch is complete.
766  *
767  * @NL80211_CMD_VENDOR: Vendor-specified command/event. The command is specified
768  *      by the %NL80211_ATTR_VENDOR_ID attribute and a sub-command in
769  *      %NL80211_ATTR_VENDOR_SUBCMD. Parameter(s) can be transported in
770  *      %NL80211_ATTR_VENDOR_DATA.
771  *      For feature advertisement, the %NL80211_ATTR_VENDOR_DATA attribute is
772  *      used in the wiphy data as a nested attribute containing descriptions
773  *      (&struct nl80211_vendor_cmd_info) of the supported vendor commands.
774  *      This may also be sent as an event with the same attributes.
775  *
776  * @NL80211_CMD_SET_QOS_MAP: Set Interworking QoS mapping for IP DSCP values.
777  *      The QoS mapping information is included in %NL80211_ATTR_QOS_MAP. If
778  *      that attribute is not included, QoS mapping is disabled. Since this
779  *      QoS mapping is relevant for IP packets, it is only valid during an
780  *      association. This is cleared on disassociation and AP restart.
781  *
782  * @NL80211_CMD_ADD_TX_TS: Ask the kernel to add a traffic stream for the given
783  *      %NL80211_ATTR_TSID and %NL80211_ATTR_MAC with %NL80211_ATTR_USER_PRIO
784  *      and %NL80211_ATTR_ADMITTED_TIME parameters.
785  *      Note that the action frame handshake with the AP shall be handled by
786  *      userspace via the normal management RX/TX framework, this only sets
787  *      up the TX TS in the driver/device.
788  *      If the admitted time attribute is not added then the request just checks
789  *      if a subsequent setup could be successful, the intent is to use this to
790  *      avoid setting up a session with the AP when local restrictions would
791  *      make that impossible. However, the subsequent "real" setup may still
792  *      fail even if the check was successful.
793  * @NL80211_CMD_DEL_TX_TS: Remove an existing TS with the %NL80211_ATTR_TSID
794  *      and %NL80211_ATTR_MAC parameters. It isn't necessary to call this
795  *      before removing a station entry entirely, or before disassociating
796  *      or similar, cleanup will happen in the driver/device in this case.
797  *
798  * @NL80211_CMD_GET_MPP: Get mesh path attributes for mesh proxy path to
799  *      destination %NL80211_ATTR_MAC on the interface identified by
800  *      %NL80211_ATTR_IFINDEX.
801  *
802  * @NL80211_CMD_JOIN_OCB: Join the OCB network. The center frequency and
803  *      bandwidth of a channel must be given.
804  * @NL80211_CMD_LEAVE_OCB: Leave the OCB network -- no special arguments, the
805  *      network is determined by the network interface.
806  *
807  * @NL80211_CMD_TDLS_CHANNEL_SWITCH: Start channel-switching with a TDLS peer,
808  *      identified by the %NL80211_ATTR_MAC parameter. A target channel is
809  *      provided via %NL80211_ATTR_WIPHY_FREQ and other attributes determining
810  *      channel width/type. The target operating class is given via
811  *      %NL80211_ATTR_OPER_CLASS.
812  *      The driver is responsible for continually initiating channel-switching
813  *      operations and returning to the base channel for communication with the
814  *      AP.
815  * @NL80211_CMD_TDLS_CANCEL_CHANNEL_SWITCH: Stop channel-switching with a TDLS
816  *      peer given by %NL80211_ATTR_MAC. Both peers must be on the base channel
817  *      when this command completes.
818  *
819  * @NL80211_CMD_WIPHY_REG_CHANGE: Similar to %NL80211_CMD_REG_CHANGE, but used
820  *      as an event to indicate changes for devices with wiphy-specific regdom
821  *      management.
822  *
823  * @NL80211_CMD_ABORT_SCAN: Stop an ongoing scan. Returns -ENOENT if a scan is
824  *      not running. The driver indicates the status of the scan through
825  *      cfg80211_scan_done().
826  *
827  * @NL80211_CMD_MAX: highest used command number
828  * @__NL80211_CMD_AFTER_LAST: internal use

1401  *      the current channel. If the current channel doesn't match and this
1402  *      flag isn't set, the frame will be rejected. This is also used as an
1403  *      nl80211 capability flag.
1404  *
1405  * @NL80211_ATTR_BSS_HT_OPMODE: HT operation mode (u16)

1417  *      the @NL80211_MESH_SETUP_USERSPACE_AUTH flag.
1418  * @NL80211_ATTR_STA_PLINK_STATE: The state of a mesh peer link as defined in
1419  *      &enum nl80211_plink_state. Used when userspace is driving the peer link

1436  *      pass-thru filter rules.
1437  *      For a match to succeed, the BSS must match all attributes of a
1438  *      set.  Since not every hardware supports matching all types of
1439  *      attributes, there is no guarantee that the reported BSSs are
1440  *      fully complying with the match sets and userspace needs to be
1441  *      able to ignore them by itself.
1442  *      Thus, the implementation is somewhat hardware-dependent, but
1443  *      this is only an optimization and the userspace application
1444  *      needs to handle all the non-filtered results anyway.
1445  *      If the match attributes don't make sense when combined with
1446  *      the values passed in @NL80211_ATTR_SCAN_SSIDS (eg. if an SSID
1447  *      is included in the probe request, but the match attributes
1448  *      will never let it go through), -EINVAL may be returned.
1449  *      If ommited, no filtering is done.

1474  *      driver (or firmware) replies to Probe Request frames.
1475  * @NL80211_ATTR_IE_ASSOC_RESP: Information element(s) for (Re)Association
1476  *      Response frames. This is used with %NL80211_CMD_NEW_BEACON and

1490  *      candidate information, see &enum nl80211_pmksa_candidate_attr.
1491  *
1492  * @NL80211_ATTR_TX_NO_CCK_RATE: Indicates whether to use CCK rate or not
1493  *      for management frames transmission. In order to avoid p2p probe/action
1494  *      frames are being transmitted at CCK rate in 2GHz band, the user space
1495  *      applications use this attribute.
1496  *      This attribute is used with %NL80211_CMD_TRIGGER_SCAN and

1511  *      used for asking the driver to perform a TDLS operation.
1512  *
1513  * @NL80211_ATTR_DEVICE_AP_SME: This u32 attribute may be listed for devices
1514  *      that have AP support to indicate that they have the AP SME integrated

3924  * DOC: TCP connection wakeup
3925  *
3926  * Some devices can establish a TCP connection in order to be woken up by a
3927  * packet coming in from outside their network segment, or behind NAT. If
3928  * configured, the device will establish a TCP connection to the given
3929  * service, and periodically send data to that service. The first data
3930  * packet is usually transmitted after SYN/ACK, also ACKing the SYN/ACK.
3931  * The data packets can optionally include a (little endian) sequence
3932  * number (in the TCP payload!) that is generated by the device, and, also
3933  * optionally, a token from a list of tokens. This serves as a keep-alive
3934  * with the service, and for NATed connections, etc.
3935  *
3936  * During this keep-alive period, the server doesn't send any data to the
3937  * client. When receiving data, it is compared against the wakeup pattern
3938  * (and mask) and if it matches, the host is woken up. Similarly, if the
3939  * connection breaks or cannot be established to start with, the host is
3940  * also woken up.
3941  *
3942  * Developer's note: ARP offload is required for this, otherwise TCP
3943  * response packets might not go through correctly.

4323  * @NL80211_FEATURE_HT_IBSS: This driver supports IBSS with HT datarates.
4324  * @NL80211_FEATURE_INACTIVITY_TIMER: This driver takes care of freeing up
4325  *      the connected inactive stations in AP mode.
4326  * @NL80211_FEATURE_CELL_BASE_REG_HINTS: This driver has been tested
4327  *      to work properly to suppport receiving regulatory hints from
4328  *      cellular base stations.
4329  * @NL80211_FEATURE_P2P_DEVICE_NEEDS_CHANNEL: (no longer available, only
4330  *      here to reserve the value for API/ABI compatibility)
4331  * @NL80211_FEATURE_SAE: This driver supports simultaneous authentication of

4333  *      mode
4334  * @NL80211_FEATURE_LOW_PRIORITY_SCAN: This driver supports low priority scan
4335  * @NL80211_FEATURE_SCAN_FLUSH: Scan flush is supported
4336  * @NL80211_FEATURE_AP_SCAN: Support scanning using an AP vif
4337  * @NL80211_FEATURE_VIF_TXPOWER: The driver supports per-vif TX power setting
4338  * @NL80211_FEATURE_NEED_OBSS_SCAN: The driver expects userspace to perform
4339  *      OBSS scans and generate 20/40 BSS coex reports. This flag is used only
4340  *      for drivers implementing the CONNECT API, for AUTH/ASSOC it is implied.

4359  *      Peering Management entity which may be implemented by registering for
4360  *      beacons or NL80211_CMD_NEW_PEER_CANDIDATE events. The mesh beacon is
4361  *      still generated by the driver.
4362  * @NL80211_FEATURE_ACTIVE_MONITOR: This driver supports an active monitor
4363  *      interface. An active monitor interface behaves like a normal monitor
4364  *      interface, but gets added to the driver. It ensures that incoming
4365  *      unicast packets directed at the configured interface address get ACKed.
4366  * @NL80211_FEATURE_AP_MODE_CHAN_WIDTH_CHANGE: This driver supports dynamic
4367  *      channel bandwidth change (e.g., HT 20 <-> 40 MHz channel) during the
4368  *      lifetime of a BSS.
4369  * @NL80211_FEATURE_DS_PARAM_SET_IE_IN_PROBES: This device adds a DS Parameter
4370  *      Set IE to probe requests.
4371  * @NL80211_FEATURE_WFA_TPC_IE_IN_PROBES: This device adds a WFA TPC Report IE
4372  *      to probe requests.
4373  * @NL80211_FEATURE_QUIET: This device, in client mode, supports Quiet Period
4374  *      requests sent to it by an AP.
4375  * @NL80211_FEATURE_TX_POWER_INSERTION: This device is capable of inserting the
4376  *      current tx power value into the TPC Report IE in the spectrum
4377  *      management TPC Report action frame, and in the Radio Measurement Link
4378  *      Measurement Report action frame.
4379  * @NL80211_FEATURE_ACKTO_ESTIMATION: This driver supports dynamic ACK timeout
4380  *      estimation (dynack). %NL80211_ATTR_WIPHY_DYN_ACK flag attribute is used
4381  *      to enable dynack.
4382  * @NL80211_FEATURE_STATIC_SMPS: Device supports static spatial
4383  *      multiplexing powersave, ie. can turn off all but one chain
4384  *      even on HT connections that should be using more chains.
4385  * @NL80211_FEATURE_DYNAMIC_SMPS: Device supports dynamic spatial
4386  *      multiplexing powersave, ie. can turn off all but one chain
4387  *      and then wake the rest up as required after, for example,
4388  *      rts/cts handshake.
4389  * @NL80211_FEATURE_SUPPORTS_WMM_ADMISSION: the device supports setting up WMM
4390  *      TSPEC sessions (TID aka TSID 0-7) with the %NL80211_CMD_ADD_TX_TS
4391  *      command. Standard IEEE 802.11 TSPEC setup is not yet supported, it
4392  *      needs to be able to handle Block-Ack agreements and other things.
4393  * @NL80211_FEATURE_MAC_ON_CREATE: Device supports configuring
4394  *      the vif's MAC address upon creation.
4395  *      See 'macaddr' field in the vif_params (cfg80211.h).

4397  *      operating as a TDLS peer.
4398  * @NL80211_FEATURE_SCAN_RANDOM_MAC_ADDR: This device/driver supports using a
4399  *      random MAC address during scan (if the device is unassociated); the
4400  *      %NL80211_SCAN_FLAG_RANDOM_ADDR flag may be set for scans and the MAC
4401  *      address mask/value will be used.
