* @dot11MeshGateAnnouncementProtocol: whether to advertise that this mesh

* missnamed in draft 12.0: dot11MeshGateAnnouncementProtocol set to true
* only means that the station will announce others it's a mesh gate, but
* not necessarily using the gate announcement protocol. Still keeping the

* @dot11MeshForwarding: whether the Mesh STA is forwarding or non-forwarding

* @dot11MeshNolearn: Try to avoid multi-hop path discovery (e.g. PREQ/PREP

* DOC: Scanning and BSS list handling

* a bit of helper functionality. To start a scan, the scan operation will
* be invoked with a scan definition. This scan definition contains the
* channels to scan, and the SSIDs to send probe requests for (including the

* probe. Additionally, a scan request may contain extra information elements
* that should be added to the probe request. The IEs are guaranteed to be
* well-formed, and will not exceed the maximum length the driver advertised
* in the wiphy structure.
*
* When scanning finds a BSS, cfg80211 needs to be notified of that, because
* it is responsible for maintaining the BSS list; the driver should not
* maintain a list itself. For this notification, various functions exist.
*
* Since drivers do not maintain a BSS list, there are also a number of
* functions to search for a BSS and obtain information about it from the
* BSS structure cfg80211 maintains. The BSS list is also made available
* to userspace.

* struct cfg80211_assoc_request - (Re)Association request data
*
* This structure provides information needed to complete IEEE 802.11
* (re)association.
* @bss: The BSS to associate with. If the call is successful the driver is
* given a reference that it must give back to cfg80211_send_rx_assoc()
* or to cfg80211_assoc_timeout(). To ensure proper refcounting, new
* association requests while already associating must be rejected.
* This also applies to the @links.bss parameter, which is used instead
* of this one (it is %NULL) for MLO associations.
* @ie: Extra IEs to add to (Re)Association Request frame or %NULL
* @ie_len: Length of ie buffer in octets
* @use_mfp: Use management frame protection (IEEE 802.11w) in this association
* @crypto: crypto settings
* @prev_bssid: previous BSSID, if not %NULL use reassociate frame. This is used
* to indicate a request to reassociate within the ESS instead of a request
* do the initial association with the ESS. When included, this is set to
* the BSSID of the current association, i.e., to the value that is
* included in the Current AP address field of the Reassociation Request
* frame.
* @flags: See &enum cfg80211_assoc_req_flags
* @supported_selectors: supported BSS selectors in IEEE 802.11 format
* (or %NULL for no change).
* If %NULL, then support for SAE_H2E should be assumed.
* @supported_selectors_len: number of supported BSS selectors
* @ht_capa: HT Capabilities over-rides. Values set in ht_capa_mask
* will be used in ht_capa. Un-supported values will be ignored.
* @ht_capa_mask: The bits of ht_capa which are to be used.
* @vht_capa: VHT capability override
* @vht_capa_mask: VHT capability mask indicating which fields to use
* @fils_kek: FILS KEK for protecting (Re)Association Request/Response frame or
* %NULL if FILS is not used.
* @fils_kek_len: Length of fils_kek in octets
* @fils_nonces: FILS nonces (part of AAD) for protecting (Re)Association
* Request/Response frame or %NULL if FILS is not used. This field starts
* with 16 octets of STA Nonce followed by 16 octets of AP Nonce.
* @s1g_capa: S1G capability override
* @s1g_capa_mask: S1G capability override mask
* @links: per-link information for MLO connections
* @link_id: >= 0 for MLO connections, where links are given, and indicates
* the link on which the association request should be sent
* @ap_mld_addr: AP MLD address in case of MLO association request,
* valid iff @link_id >= 0
* @ext_mld_capa_ops: extended MLD capabilities and operations set by
* userspace for the association

* RSN IE. It allows for faster roaming between WPA2 BSSIDs.
* @del_pmksa: Delete a cached PMKID.
* @flush_pmksa: Flush all cached PMKIDs.
* @set_power_mgmt: Configure WLAN power management. A timeout value of -1
* allows the driver to adjust the dynamic ps timeout value.
* @set_cqm_rssi_config: Configure connection quality monitor RSSI threshold.
* After configuration, the driver should (soon) send an event indicating
* the current level is above/below the configured threshold; this may
* need some care when the configuration is changed (without first being
* disabled.)
* @set_cqm_rssi_range_config: Configure two RSSI thresholds in the
* connection quality monitor. An event is to be sent only when the
* signal level is found to be outside the two values. The driver should
* set %NL80211_EXT_FEATURE_CQM_RSSI_LIST ifthis method is implemented.
* If it is provided then there's no point providing @set_cqm_rssi_config.
* @set_cqm_txe_config: Configure connection quality monitor TX error
* thresholds.
* @sched_scan_start: Tell the driver to start a scheduled scan.
* @sched_scan_stop: Tell the driver to stop an ongoing scheduled scan with
* given request id. This call must stop the scheduled scan and be ready
* for starting a new one before it returns, i.e. @sched_scan_start may be
* called immediately after that again and should not fail in that case.
* The driver should not call cfg80211_sched_scan_stopped() for a requested
* stop (when this method returns 0).
*
* @update_mgmt_frame_registrations: Notify the driver that management frame
* registrations were updated. The callback is allowed to sleep.
*
* @set_antenna: Set antenna configuration (tx_ant, rx_ant) on the device.
* Parameters are bitmaps of allowed antennas to use for TX/RX. Drivers may
* reject TX/RX mask combinations they cannot support by returning -EINVAL
* (also see nl80211.h @NL80211_ATTR_WIPHY_ANTENNA_TX).
*
* @get_antenna: Get current antenna configuration from device (tx_ant, rx_ant).
*
* @tdls_mgmt: Transmit a TDLS management frame.
* @tdls_oper: Perform a high-level TDLS operation (e.g. TDLS link setup).
*
* @probe_client: probe an associated client, must return a cookie that it
* later passes to cfg80211_probe_status().
*
* @set_noack_map: Set the NoAck Map for the TIDs.
*
* @get_channel: Get the current operating channel for the virtual interface.
* For monitor interfaces, it should return %NULL unless there's a single
* current monitoring channel.
*
* @start_p2p_device: Start the given P2P device.
* @stop_p2p_device: Stop the given P2P device.
*
* @set_mac_acl: Sets MAC address control list in AP and P2P GO mode.
* Parameters include ACL policy, an array of MAC address of stations
* and the number of MAC addresses. If there is already a list in driver
* thisnew list replaces the existing one. Driver has to clear its ACL
* when number of MAC addresses entries is passed as 0. Drivers which
* advertise the support for MAC based ACL have to implement this callback.
*
* @start_radar_detection: Start radar detection in the driver.
*
* @end_cac: End running CAC, probably because a related CAC
* was finished on another phy.
*
* @update_ft_ies: Provide updated Fast BSS Transition information to the
* driver. If the SME is in the driver/firmware, this information can be
* used in building Authentication and Reassociation Request frames.
*
* @crit_proto_start: Indicates a critical protocol needs more link reliability
* for a given duration (milliseconds). The protocol is provided so the
* driver can take the most appropriate actions.
* @crit_proto_stop: Indicates critical protocol no longer needs increased link
* reliability. This operation can not fail.
* @set_coalesce: Set coalesce parameters.
*
* @channel_switch: initiate channel-switch procedure (with CSA). Driver is
* responsible for veryfing if the switch is possible. Since this is
* inherently tricky driver may decide to disconnect an interface later
* with cfg80211_stop_iface(). This doesn't mean driver can accept
* everything. It should do it's best to verify requests and reject them
* as soon as possible.
*
* @set_qos_map: Set QoS mapping information to the driver
*
* @set_ap_chanwidth: Set the AP (including P2P GO) mode channel width for the
* given interface This is used e.g. for dynamic HT 20/40 MHz channel width
* changes during the lifetime of the BSS.
*
* @add_tx_ts: validate (if admitted_time is 0) or add a TX TS to the device
* with the given parameters; action frame exchange has been handled by
* userspace so this just has to modify the TX path to take the TS into
* account.
* If the admitted time is 0 just validate the parameters to make sure
