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

1349 * DOC: Scanning and BSS list handling
1351 * The scanning process itself is fairly simple, but cfg80211 offers quite
1352 * a bit of helper functionality. To start a scan, the scan operation will
1353 * be invoked with a scan definition. This scan definition contains the
1354 * channels to scan, and the SSIDs to send probe requests for (including the
1355 * wildcard, if desired). A passive scan is indicated by having no SSIDs to
1356 * probe. Additionally, a scan request may contain extra information elements
1357 * that should be added to the probe request. The IEs are guaranteed to be
1358 * well-formed, and will not exceed the maximum length the driver advertised
1359 * in the wiphy structure.
1361 * When scanning finds a BSS, cfg80211 needs to be notified of that, because
1362 * it is responsible for maintaining the BSS list; the driver should not
1363 * maintain a list itself. For this notification, various functions exist.
1365 * Since drivers do not maintain a BSS list, there are also a number of
1366 * functions to search for a BSS and obtain information about it from the
1367 * BSS structure cfg80211 maintains. The BSS list is also made available

2278 * @remain_on_channel: Request the driver to remain awake on the specified
2279 * channel for the specified duration to complete an off-channel
2280 * operation (e.g., public action frame exchange). When the driver is
2281 * ready on the requested channel, it must indicate this with an event
2282 * notification by calling cfg80211_ready_on_channel().
2283 * @cancel_remain_on_channel: Cancel an on-going remain-on-channel operation.
2284 * This allows the operation to be terminated prior to timeout based on

2293 * return error codes other than -ENOBUFS and -ENOENT will terminate the
2294 * dump and return to userspace with an error, so be careful. If any data
2295 * was passed in from userspace then the data/len arguments will be present
2296 * and point to the data contained in %NL80211_ATTR_TESTDATA.
2298 * @set_bitrate_mask: set the bitrate mask configuration
2300 * @set_pmksa: Cache a PMKID for a BSSID. This is mostly useful for fullmac

2310 * @sched_scan_start: Tell the driver to start a scheduled scan.
2311 * @sched_scan_stop: Tell the driver to stop an ongoing scheduled scan. This
2312 * call must stop the scheduled scan and be ready for starting a new one
2313 * before it returns, i.e. @sched_scan_start may be called immediately
2314 * after that again and should not fail in that case. The driver should
2315 * not call cfg80211_sched_scan_stopped() for a requested stop (when this
2316 * method returns 0.)
2318 * @mgmt_frame_register: Notify driver that a management frame type was
2319 * registered. Note that this callback may not sleep, and cannot run
2320 * concurrently with itself.
2322 * @set_antenna: Set antenna configuration (tx_ant, rx_ant) on the device.
2323 * Parameters are bitmaps of allowed antennas to use for TX/RX. Drivers may
2324 * reject TX/RX mask combinations they cannot support by returning -EINVAL
2325 * (also see nl80211.h @NL80211_ATTR_WIPHY_ANTENNA_TX).
2327 * @get_antenna: Get current antenna configuration from device (tx_ant, rx_ant).
2329 * @tdls_mgmt: Transmit a TDLS management frame.
2330 * @tdls_oper: Perform a high-level TDLS operation (e.g. TDLS link setup).
2332 * @probe_client: probe an associated client, must return a cookie that it
2333 * later passes to cfg80211_probe_status().
2335 * @set_noack_map: Set the NoAck Map for the TIDs.
2337 * @get_channel: Get the current operating channel for the virtual interface.
2338 * For monitor interfaces, it should return %NULL unless there's a single
2339 * current monitoring channel.
2341 * @start_p2p_device: Start the given P2P device.
2342 * @stop_p2p_device: Stop the given P2P device.
2344 * @set_mac_acl: Sets MAC address control list in AP and P2P GO mode.
2345 * Parameters include ACL policy, an array of MAC address of stations
2346 * and the number of MAC addresses. If there is already a list in driver
2347 * this new list replaces the existing one. Driver has to clear its ACL
2348 * when number of MAC addresses entries is passed as 0. Drivers which
2349 * advertise the support for MAC based ACL have to implement this callback.
2351 * @start_radar_detection: Start radar detection in the driver.
2353 * @update_ft_ies: Provide updated Fast BSS Transition information to the
2354 * driver. If the SME is in the driver/firmware, this information can be
2355 * used in building Authentication and Reassociation Request frames.
2357 * @crit_proto_start: Indicates a critical protocol needs more link reliability
2358 * for a given duration (milliseconds). The protocol is provided so the
2359 * driver can take the most appropriate actions.
2360 * @crit_proto_stop: Indicates critical protocol no longer needs increased link
2361 * reliability. This operation can not fail.
2362 * @set_coalesce: Set coalesce parameters.
2364 * @channel_switch: initiate channel-switch procedure (with CSA). Driver is
2365 * responsible for veryfing if the switch is possible. Since this is
2366 * inherently tricky driver may decide to disconnect an interface later
2367 * with cfg80211_stop_iface(). This doesn't mean driver can accept
2368 * everything. It should do it's best to verify requests and reject them
2369 * as soon as possible.
2371 * @set_qos_map: Set QoS mapping information to the driver
2373 * @set_ap_chanwidth: Set the AP (including P2P GO) mode channel width for the
2374 * given interface This is used e.g. for dynamic HT 20/40 MHz channel width
2375 * changes during the lifetime of the BSS.
2377 * @add_tx_ts: validate (if admitted_time is 0) or add a TX TS to the device
2378 * with the given parameters; action frame exchange has been handled by
2379 * userspace so this just has to modify the TX path to take the TS into
2381 * If the admitted time is 0 just validate the parameters to make sure
2382 * the session can be created at all; it is valid to just always return
2383 * success for that but that may result in inefficient behaviour (handshake
2384 * with the peer followed by immediate teardown when the addition is later
2386 * @del_tx_ts: remove an existing TX TS
2388 * @join_ocb: join the OCB network with the specified parameters
2389 * (invoked with the wireless_dev mutex held)
2390 * @leave_ocb: leave the current OCB network
2391 * (invoked with the wireless_dev mutex held)
2393 * @tdls_channel_switch: Start channel-switching with a TDLS peer. The driver
2394 * is responsible for continually initiating channel-switching operations
2395 * and returning to the base channel for communication with the AP.
2396 * @tdls_cancel_channel_switch: Stop channel-switching with a TDLS peer. Both
2397 * peers must be on the base channel when the call completes.
