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

841 * DOC: Scanning and BSS list handling
843 * The scanning process itself is fairly simple, but cfg80211 offers quite
844 * a bit of helper functionality. To start a scan, the scan operation will
845 * be invoked with a scan definition. This scan definition contains the
846 * channels to scan, and the SSIDs to send probe requests for (including the
847 * wildcard, if desired). A passive scan is indicated by having no SSIDs to
848 * probe. Additionally, a scan request may contain extra information elements
849 * that should be added to the probe request. The IEs are guaranteed to be
850 * well-formed, and will not exceed the maximum length the driver advertised
851 * in the wiphy structure.
853 * When scanning finds a BSS, cfg80211 needs to be notified of that, because
854 * it is responsible for maintaining the BSS list; the driver should not
855 * maintain a list itself. For this notification, various functions exist.
857 * Since drivers do not maintain a BSS list, there are also a number of
858 * functions to search for a BSS and obtain information about it from the
859 * BSS structure cfg80211 maintains. The BSS list is also made available

1336 * @update_mesh_config: Update mesh parameters on a running mesh.
1337 * The mask is a bitfield which tells us which parameters to
1338 * set, and which to leave alone.
1340 * @change_bss: Modify parameters for a given BSS.
1342 * @set_txq_params: Set TX queue parameters
1344 * @set_channel: Set channel for a given wireless interface. Some devices
1345 * may support multi-channel operation (by channel hopping) so cfg80211
1346 * doesn't verify much. Note, however, that the passed netdev may be
1347 * %NULL as well if the user requested changing the channel for the
1348 * device itself, or for a monitor interface.
1349 * @get_channel: Get the current operating channel, should return %NULL if
1350 * there's no single defined operating channel if for example the
1351 * device implements channel hopping for multi-channel virtual interfaces.
1353 * @scan: Request to do a scan. If returning zero, the scan request is given
1354 * the driver, and will be valid until passed to cfg80211_scan_done().
1355 * For scan results, call cfg80211_inform_bss(); you can call this outside
1356 * the scan/scan_done bracket too.
1358 * @auth: Request to authenticate with the specified peer
1359 * @assoc: Request to (re)associate with the specified peer
1360 * @deauth: Request to deauthenticate from the specified peer
1361 * @disassoc: Request to disassociate from the specified peer
1363 * @connect: Connect to the ESS with the specified parameters. When connected,
1364 * call cfg80211_connect_result() with status code %WLAN_STATUS_SUCCESS.
1365 * If the connection fails for some reason, call cfg80211_connect_result()
1366 * with the status from the AP.
1367 * @disconnect: Disconnect from the BSS/ESS.
1369 * @join_ibss: Join the specified IBSS (or create if necessary). Once done, call
1370 * cfg80211_ibss_joined(), also call that function when changing BSSID due
1372 * @leave_ibss: Leave the IBSS.
1374 * @set_wiphy_params: Notify that wiphy parameters have changed;
1375 * @changed bitfield (see &enum wiphy_params_flags) describes which values
1376 * have changed. The actual parameter values are available in
1377 * struct wiphy. If returning an error, no value should be changed.
1379 * @set_tx_power: set the transmit power according to the parameters
1380 * @get_tx_power: store the current TX power into the dbm variable;
1381 * return 0 if successful
1383 * @set_wds_peer: set the WDS peer for a WDS interface
1385 * @rfkill_poll: polls the hw rfkill line, use cfg80211 reporting
1386 * functions to adjust rfkill hw state
1388 * @dump_survey: get site survey information.
1390 * @remain_on_channel: Request the driver to remain awake on the specified
1391 * channel for the specified duration to complete an off-channel
1392 * operation (e.g., public action frame exchange). When the driver is
1393 * ready on the requested channel, it must indicate this with an event
1394 * notification by calling cfg80211_ready_on_channel().
1395 * @cancel_remain_on_channel: Cancel an on-going remain-on-channel operation.
1396 * This allows the operation to be terminated prior to timeout based on
1397 * the duration value.
1398 * @mgmt_tx: Transmit a management frame.
1399 * @mgmt_tx_cancel_wait: Cancel the wait time from transmitting a management
1400 * frame on another channel
1402 * @testmode_cmd: run a test mode command
1403 * @testmode_dump: Implement a test mode dump. The cb->args[2] and up may be
1404 * used by the function, but 0 and 1 must not be touched. Additionally,
1405 * return error codes other than -ENOBUFS and -ENOENT will terminate the
1406 * dump and return to userspace with an error, so be careful. If any data
1407 * was passed in from userspace then the data/len arguments will be present
1408 * and point to the data contained in %NL80211_ATTR_TESTDATA.
1410 * @set_bitrate_mask: set the bitrate mask configuration
1412 * @set_pmksa: Cache a PMKID for a BSSID. This is mostly useful for fullmac
1413 * devices running firmwares capable of generating the (re) association
1414 * RSN IE. It allows for faster roaming between WPA2 BSSIDs.
1415 * @del_pmksa: Delete a cached PMKID.
1416 * @flush_pmksa: Flush all cached PMKIDs.
1417 * @set_power_mgmt: Configure WLAN power management. A timeout value of -1
1418 * allows the driver to adjust the dynamic ps timeout value.
1419 * @set_cqm_rssi_config: Configure connection quality monitor RSSI threshold.
1420 * @sched_scan_start: Tell the driver to start a scheduled scan.
1421 * @sched_scan_stop: Tell the driver to stop an ongoing scheduled
1422 * scan. The driver_initiated flag specifies whether the driver
1423 * itself has informed that the scan has stopped.
1425 * @mgmt_frame_register: Notify driver that a management frame type was
1426 * registered. Note that this callback may not sleep, and cannot run
1427 * concurrently with itself.
1429 * @set_antenna: Set antenna configuration (tx_ant, rx_ant) on the device.
1430 * Parameters are bitmaps of allowed antennas to use for TX/RX. Drivers may
1431 * reject TX/RX mask combinations they cannot support by returning -EINVAL
1432 * (also see nl80211.h @NL80211_ATTR_WIPHY_ANTENNA_TX).
1434 * @get_antenna: Get current antenna configuration from device (tx_ant, rx_ant).
1436 * @set_ringparam: Set tx and rx ring sizes.
1438 * @get_ringparam: Get tx and rx ring current and maximum sizes.
1440 * @tdls_mgmt: Transmit a TDLS management frame.
1441 * @tdls_oper: Perform a high-level TDLS operation (e.g. TDLS link setup).
1443 * @probe_client: probe an associated client, must return a cookie that it
1444 * later passes to cfg80211_probe_status().
1446 * @notify_btcoex_inq_status: Notify the Bluetooth inquiry status in
1447 * case of a Bleutooth co-ex device.
1449 * @notify_btcoex_sco_status: Notify the Bluetooth SCO connection status in
1450 * case of a Bluetooth co-ex device.
