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

1074 * DOC: Scanning and BSS list handling
1076 * The scanning process itself is fairly simple, but cfg80211 offers quite
1077 * a bit of helper functionality. To start a scan, the scan operation will
1078 * be invoked with a scan definition. This scan definition contains the
1079 * channels to scan, and the SSIDs to send probe requests for (including the
1080 * wildcard, if desired). A passive scan is indicated by having no SSIDs to
1081 * probe. Additionally, a scan request may contain extra information elements
1082 * that should be added to the probe request. The IEs are guaranteed to be
1083 * well-formed, and will not exceed the maximum length the driver advertised
1084 * in the wiphy structure.
1086 * When scanning finds a BSS, cfg80211 needs to be notified of that, because
1087 * it is responsible for maintaining the BSS list; the driver should not
1088 * maintain a list itself. For this notification, various functions exist.
1090 * Since drivers do not maintain a BSS list, there are also a number of
1091 * functions to search for a BSS and obtain information about it from the
1092 * BSS structure cfg80211 maintains. The BSS list is also made available

1614 * might come to the driver in invalid combinations -- make sure to check
1615 * them, also against the existing state! Also, supported_rates changes are

1643 * @set_monitor_channel: Set the monitor mode channel for the device. If other
1644 * interfaces are active this callback should reject the configuration.
1645 * If no interfaces are active or the device is down, the channel should
1646 * be stored for when a monitor interface becomes active.
1648 * @scan: Request to do a scan. If returning zero, the scan request is given
1649 * the driver, and will be valid until passed to cfg80211_scan_done().

1661 * with the status from the AP.
1662 * @disconnect: Disconnect from the BSS/ESS.
1664 * @join_ibss: Join the specified IBSS (or create if necessary). Once done, call

1672 * @set_wiphy_params: Notify that wiphy parameters have changed;
1673 * @changed bitfield (see &enum wiphy_params_flags) describes which values
1674 * have changed. The actual parameter values are available in
1675 * struct wiphy. If returning an error, no value should be changed.
1677 * @set_tx_power: set the transmit power according to the parameters,
1678 * the power passed is in mBm, to get dBm use MBM_TO_DBM(). The
1679 * wdev may be %NULL if power was set for the wiphy, and will

1688 * functions to adjust rfkill hw state
1690 * @dump_survey: get site survey information.
1692 * @remain_on_channel: Request the driver to remain awake on the specified
1693 * channel for the specified duration to complete an off-channel
1694 * operation (e.g., public action frame exchange). When the driver is
1695 * ready on the requested channel, it must indicate this with an event
1696 * notification by calling cfg80211_ready_on_channel().
1697 * @cancel_remain_on_channel: Cancel an on-going remain-on-channel operation.
1698 * This allows the operation to be terminated prior to timeout based on
1699 * the duration value.
1700 * @mgmt_tx: Transmit a management frame.
1701 * @mgmt_tx_cancel_wait: Cancel the wait time from transmitting a management
1702 * frame on another channel
1704 * @testmode_cmd: run a test mode command
1705 * @testmode_dump: Implement a test mode dump. The cb->args[2] and up may be
1706 * used by the function, but 0 and 1 must not be touched. Additionally,
1707 * return error codes other than -ENOBUFS and -ENOENT will terminate the
1708 * dump and return to userspace with an error, so be careful. If any data
1709 * was passed in from userspace then the data/len arguments will be present
1710 * and point to the data contained in %NL80211_ATTR_TESTDATA.
1712 * @set_bitrate_mask: set the bitrate mask configuration
1714 * @set_pmksa: Cache a PMKID for a BSSID. This is mostly useful for fullmac
1715 * devices running firmwares capable of generating the (re) association

1717 * @del_pmksa: Delete a cached PMKID.
1718 * @flush_pmksa: Flush all cached PMKIDs.
1719 * @set_power_mgmt: Configure WLAN power management. A timeout value of -1

1722 * @set_cqm_txe_config: Configure connection quality monitor TX error
1724 * @sched_scan_start: Tell the driver to start a scheduled scan.
1725 * @sched_scan_stop: Tell the driver to stop an ongoing scheduled scan.
1727 * @mgmt_frame_register: Notify driver that a management frame type was
1728 * registered. Note that this callback may not sleep, and cannot run
1729 * concurrently with itself.
1731 * @set_antenna: Set antenna configuration (tx_ant, rx_ant) on the device.
1732 * Parameters are bitmaps of allowed antennas to use for TX/RX. Drivers may
1733 * reject TX/RX mask combinations they cannot support by returning -EINVAL
1734 * (also see nl80211.h @NL80211_ATTR_WIPHY_ANTENNA_TX).

2203 * the reg_notifier's request can be passed as NULL
2204 * @regd: the driver's regulatory domain, if one was requested via
2205 * the regulatory_hint() API. This can be used by the driver
2206 * on the reg_notifier() if it chooses to ignore future
2207 * regulatory domain changes caused by other drivers.
2208 * @signal_type: signal type reported in &struct cfg80211_bss.

2221 * variable bits shall be determined by the interfaces added, with
2222 * interfaces not matching the mask being rejected to be brought up.
2223 * @n_addresses: number of addresses in @addresses.

2245 * @features: features advertised to nl80211, see &enum nl80211_feature_flags.
2246 * @bss_priv_size: each BSS struct has private data allocated with it,
2247 * this variable determines its size

3265 * However, devices may have a hard RFkill line, in which case they
