- * DOC: Introduction
- *
- * cfg80211 is the configuration API for 802.11 devices in Linux. It bridges
- * userspace and drivers, and offers some utility functionality associated
- * with 802.11. cfg80211 must, directly or indirectly via mac80211, be used
- * by all modern wireless drivers in Linux, so that they offer a consistent
- * API through nl80211. For backward compatibility, cfg80211 also offers
- * wireless extensions to userspace, but hides them from drivers completely.
- *
- * Additionally, cfg80211 contains code to help enforce regulatory spectrum
- * use restrictions.
- */
- /**
- * DOC: Device registration
- *
- * In order for a driver to use cfg80211, it must register the hardware device
- * with cfg80211. This happens through a number of hardware capability structs
- * described below.
- *
- * The fundamental structure for each device is the 'wiphy', of which each
- * instance describes a physical wireless device connected to the system. Each
- * such wiphy can have zero, one, or many virtual interfaces associated with
- * it, which need to be identified as such by pointing the network interface's
- * @ieee80211_ptr pointer to a &struct wireless_dev which further describes
- * the wireless part of the interface, normally this struct is embedded in the
- * network interface's private data area. Drivers can optionally allow creating
- * or destroying virtual interfaces on the fly, but without at least one or the
- * ability to create some the wireless device isn't useful.
- *
- * Each wiphy structure contains device capability information, and also has
- * a pointer to the various operations the driver offers. The definitions and
- * structures here describe these capabilities in detail.

- *
- * @add_virtual_intf: create a new virtual interface with the given name,
- * must set the struct wireless_dev's iftype. Beware: You must create
- * the new netdev in the wiphy's network namespace! Returns the struct
- * wireless_dev, or an ERR_PTR. For P2P device wdevs, the driver must
- * also set the address member in the wdev.
- * This additionally holds the RTNL to be able to do netdev changes.
- *

- * This additionally holds the RTNL to be able to do netdev changes.
- *
- * @add_intf_link: Add a new MLO link to the given interface. Note that

- * @del_key: remove a key given the @mac_addr (%NULL for a group key)
- * and @key_index, return -ENOENT if the key doesn't exist. @link_id will

- * @stop_ap: Stop being an AP, including stopping beaconing.
- *
- * @add_station: Add a new station.
- * @del_station: Remove a station
- * @change_station: Modify a given station. Note that flags changes are not much
- * validated in cfg80211, in particular the auth/assoc/authorized flags
- * might come to the driver in invalid combinations -- make sure to check
- * them, also against the existing state! Drivers must call
- * cfg80211_check_station_change() to validate the information.
- * @get_station: get station information for the station identified by @mac
- * @dump_station: dump station callback -- resume dump at index @idx
- *
- * @add_mpath: add a fixed mesh path
- * @del_mpath: delete a given mesh path
- * @change_mpath: change a given mesh path

- * (invoked with the wireless_dev mutex held)
- *
- * @get_mesh_config: Get the current mesh configuration
- *
- * @update_mesh_config: Update mesh parameters on a running mesh.
- * The mask is a bitfield which tells us which parameters to
- * set, and which to leave alone.
- *
- * @change_bss: Modify parameters for a given BSS.
- *
- * @set_txq_params: Set TX queue parameters
- *
- * @libertas_set_mesh_channel: Only for backward compatibility for libertas,
- * as it doesn't implement join_mesh and needs to set the channel to
- * join the mesh instead.
- *
- * @set_monitor_channel: Set the monitor mode channel for the device. If other
- * interfaces are active this callback should reject the configuration.
- * If no interfaces are active or the device is down, the channel should
- * be stored for when a monitor interface becomes active.
- *
- * @scan: Request to do a scan. If returning zero, the scan request is given
- * the driver, and will be valid until passed to cfg80211_scan_done().
- * For scan results, call cfg80211_inform_bss(); you can call this outside
- * the scan/scan_done bracket too.
- * @abort_scan: Tell the driver to abort an ongoing scan. The driver shall
- * indicate the status of the scan through cfg80211_scan_done().
- *
- * @auth: Request to authenticate with the specified peer

- * (invoked with the wireless_dev mutex held)
- * @disassoc: Request to disassociate from the specified peer
- * (invoked with the wireless_dev mutex held)
- *
- * @connect: Connect to the ESS with the specified parameters. When connected,
- * call cfg80211_connect_result()/cfg80211_connect_bss() with status code
- * %WLAN_STATUS_SUCCESS. If the connection fails for some reason, call
- * cfg80211_connect_result()/cfg80211_connect_bss() with the status code
- * from the AP or cfg80211_connect_timeout() if no frame with status code
- * was received.
- * The driver is allowed to roam to other BSSes within the ESS when the
- * other BSS matches the connect parameters. When such roaming is initiated
- * by the driver, the driver is expected to verify that the target matches
- * the configured security parameters and to use Reassociation Request
- * frame instead of Association Request frame.
- * The connect function can also be used to request the driver to perform a
- * specific roam when connected to an ESS. In that case, the prev_bssid
- * parameter is set to the BSSID of the currently associated BSS as an
- * indication of requesting reassociation.
- * In both the driver-initiated and new connect() call initiated roaming
- * cases, the result of roaming is indicated with a call to
- * cfg80211_roamed(). (invoked with the wireless_dev mutex held)
- * @update_connect_params: Update the connect parameters while connected to a
- * BSS. The updated parameters can be used by driver/firmware for
- * subsequent BSS selection (roaming) decisions and to form the
- * Authentication/(Re)Association Request frames. This call does not
- * request an immediate disassociation or reassociation with the current
- * BSS, i.e., this impacts only subsequent (re)associations. The bits in
- * changed are defined in &enum cfg80211_connect_params_changed.
- * (invoked with the wireless_dev mutex held)
- * @disconnect: Disconnect from the BSS/ESS or stop connection attempts if
- * connection is in progress. Once done, call cfg80211_disconnected() in
- * case connection was already established (invoked with the
- * wireless_dev mutex held), otherwise call cfg80211_connect_timeout().
- *
- * @join_ibss: Join the specified IBSS (or create if necessary). Once done, call
- * cfg80211_ibss_joined(), also call that function when changing BSSID due
- * to a merge.
- * (invoked with the wireless_dev mutex held)
- * @leave_ibss: Leave the IBSS.
- * (invoked with the wireless_dev mutex held)
- *
- * @set_mcast_rate: Set the specified multicast rate (only if vif is in ADHOC or
- * MESH mode)
- *
- * @set_wiphy_params: Notify that wiphy parameters have changed;
- * @changed bitfield (see &enum wiphy_params_flags) describes which values
- * have changed. The actual parameter values are available in
- * struct wiphy. If returning an error, no value should be changed.
- *
- * @set_tx_power: set the transmit power according to the parameters,
- * the power passed is in mBm, to get dBm use MBM_TO_DBM(). The
- * wdev may be %NULL if power was set for the wiphy, and will
- * always be %NULL unless the driver supports per-vif TX power
- * (as advertised by the nl80211 feature flag.)
- * @get_tx_power: store the current TX power into the dbm variable;
- * return 0 if successful
- *
- * @rfkill_poll: polls the hw rfkill line, use cfg80211 reporting
- * functions to adjust rfkill hw state
- *
- * @dump_survey: get site survey information.
- *
- * @remain_on_channel: Request the driver to remain awake on the specified
- * channel for the specified duration to complete an off-channel
- * operation (e.g., public action frame exchange). When the driver is
- * ready on the requested channel, it must indicate this with an event
- * notification by calling cfg80211_ready_on_channel().
- * @cancel_remain_on_channel: Cancel an on-going remain-on-channel operation.
- * This allows the operation to be terminated prior to timeout based on
- * the duration value.
- * @mgmt_tx: Transmit a management frame.
- * @mgmt_tx_cancel_wait: Cancel the wait time from transmitting a management
- * frame on another channel
- *
- * @testmode_cmd: run a test mode command; @wdev may be %NULL
- * @testmode_dump: Implement a test mode dump. The cb->args[2] and up may be
- * used by the function, but 0 and 1 must not be touched. Additionally,
- * return error codes other than -ENOBUFS and -ENOENT will terminate the
- * dump and return to userspace with an error, so be careful. If any data
- * was passed in from userspace then the data/len arguments will be present
- * and point to the data contained in %NL80211_ATTR_TESTDATA.
- *
- * @set_bitrate_mask: set the bitrate mask configuration
- *
- * @set_pmksa: Cache a PMKID for a BSSID. This is mostly useful for fullmac
- * devices running firmwares capable of generating the (re) 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 if this 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
- * this new 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
- * the session can be created at all; it is valid to just always return
- * success for that but that may result in inefficient behaviour (handshake
- * with the peer followed by immediate teardown when the addition is later
- * rejected)

- *
- * @join_ocb: join the OCB network with the specified parameters
- * (invoked with the wireless_dev mutex held)
- * @leave_ocb: leave the current OCB network
- * (invoked with the wireless_dev mutex held)
- *
- * @tdls_channel_switch: Start channel-switching with a TDLS peer. The driver
- * is responsible for continually initiating channel-switching operations
- * and returning to the base channel for communication with the AP.
- * @tdls_cancel_channel_switch: Stop channel-switching with a TDLS peer. Both
- * peers must be on the base channel when the call completes.
- * @start_nan: Start the NAN interface.
- * @stop_nan: Stop the NAN interface.
- * @add_nan_func: Add a NAN function. Returns negative value on failure.
- * On success @nan_func ownership is transferred to the driver and
- * it may access it outside of the scope of this function. The driver
- * should free the @nan_func when no longer needed by calling
- * cfg80211_free_nan_func().
- * On success the driver should assign an instance_id in the
- * provided @nan_func.
- * @del_nan_func: Delete a NAN function.
- * @nan_change_conf: changes NAN configuration. The changed parameters must
- * be specified in @changes (using &enum cfg80211_nan_conf_changes);
- * All other parameters must be ignored.
- *
- * @set_multicast_to_unicast: configure multicast to unicast conversion for BSS
- *
- * @get_txq_stats: Get TXQ stats for interface or phy. If wdev is %NULL, this
- * function should return phy stats, and interface stats otherwise.
- *
- * @set_pmk: configure the PMK to be used for offloaded 802.1X 4-Way handshake.
- * If not deleted through @del_pmk the PMK remains valid until disconnect
- * upon which the driver should clear it.
- * (invoked with the wireless_dev mutex held)
- * @del_pmk: delete the previously configured PMK for the given authenticator.
- * (invoked with the wireless_dev mutex held)
- *
- * @external_auth: indicates result of offloaded authentication processing from
- * user space
- *
- * @tx_control_port: TX a control port frame (EAPoL). The noencrypt parameter
- * tells the driver that the frame should not be encrypted.
- *
- * @get_ftm_responder_stats: Retrieve FTM responder statistics, if available.
- * Statistics should be cumulative, currently no way to reset is provided.
- * @start_pmsr: start peer measurement (e.g. FTM)
- * @abort_pmsr: abort peer measurement
- *
- * @update_owe_info: Provide updated OWE info to driver. Driver implementing SME
- * but offloading OWE processing to the user space will get the updated
- * DH IE through this interface.
- *
- * @probe_mesh_link: Probe direct Mesh peer's link quality by sending data frame
- * and overrule HWMP path selection algorithm.
- * @set_tid_config: TID specific configuration, this can be peer or BSS specific
- * This callback may sleep.

- * given TIDs. This callback may sleep.
- *
- * @set_sar_specs: Update the SAR (TX power) settings.
- *
- * @color_change: Initiate a color change.
- *
- * @set_fils_aad: Set FILS AAD data to the AP driver so that the driver can use
- * those to decrypt (Re)Association Request and encrypt (Re)Association
- * Response frame.
- *
- * @set_radar_background: Configure dedicated offchannel chain available for
- * radar/CAC detection on some hw. This chain can't be used to transmit
- * or receive frames and it is bounded to a running wdev.
- * Background radar/CAC detection allows to avoid the CAC downtime
- * switching to a different channel during CAC detection on the selected
- * radar channel.
- * The caller is expected to set chandef pointer to NULL in order to
- * disable background CAC/radar detection.
- * @add_link_station: Add a link to a station.
- * @mod_link_station: Modify a link of a station.
- * @del_link_station: Remove a link of a station.

- * reason to override the default
- * @WIPHY_FLAG_4ADDR_AP: supports 4addr mode even on AP (with a single station

- * supporting 4ADDR AP mode on devices which do not support AP/VLAN iftype.
- * @WIPHY_FLAG_4ADDR_STATION: supports 4addr mode even as a station
- * @WIPHY_FLAG_CONTROL_PORT_PROTOCOL: This device supports setting the

- * control_port_no_encrypt flag.
- * @WIPHY_FLAG_IBSS_RSN: The device supports IBSS RSN.
- * @WIPHY_FLAG_MESH_AUTH: The device supports mesh authentication by routing
- * auth frames to userspace. See @NL80211_MESH_SETUP_USERSPACE_AUTH.

- * @WIPHY_FLAG_TDLS_EXTERNAL_SETUP: The device does not handle TDLS (802.11z)
- * link setup/discovery operations internally. Setup, discovery and
- * teardown packets should be sent through the @NL80211_CMD_TDLS_MGMT
- * command. When this flag is not set, @NL80211_CMD_TDLS_OPER should be
- * used for asking the driver/firmware to perform a TDLS operation.

- * @WIPHY_FLAG_REPORTS_OBSS: the device will report beacons from other BSSes
- * when there are virtual interfaces in AP mode by calling

- * @WIPHY_FLAG_OFFCHAN_TX: Device supports direct off-channel TX.
- * @WIPHY_FLAG_HAS_REMAIN_ON_CHANNEL: Device supports remain-on-channel call.
