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.

1131 * a bit of helper functionality. To start a scan, the scan operation will
1132 * be invoked with a scan definition. This scan definition contains the

1134 * wildcard, if desired). A passive scan is indicated by having no SSIDs to
1135 * probe. Additionally, a scan request may contain extra information elements
1136 * that should be added to the probe request. The IEs are guaranteed to be
1137 * well-formed, and will not exceed the maximum length the driver advertised
1138 * in the wiphy structure.
1140 * When scanning finds a BSS, cfg80211 needs to be notified of that, because
1141 * it is responsible for maintaining the BSS list; the driver should not
1142 * maintain a list itself. For this notification, various functions exist.
1144 * Since drivers do not maintain a BSS list, there are also a number of

1700 * interfaces are active this callback should reject the configuration.
1701 * If no interfaces are active or the device is down, the channel should
1702 * be stored for when a monitor interface becomes active.
1704 * @scan: Request to do a scan. If returning zero, the scan request is given
1705 * the driver, and will be valid until passed to cfg80211_scan_done().

1728 * @set_wiphy_params: Notify that wiphy parameters have changed;
1729 * @changed bitfield (see &enum wiphy_params_flags) describes which values
1730 * have changed. The actual parameter values are available in
1731 * struct wiphy. If returning an error, no value should be changed.
1733 * @set_tx_power: set the transmit power according to the parameters,
1734 * the power passed is in mBm, to get dBm use MBM_TO_DBM(). The
1735 * wdev may be %NULL if power was set for the wiphy, and will
1736 * always be %NULL unless the driver supports per-vif TX power
1737 * (as advertised by the nl80211 feature flag.)

1748 * @remain_on_channel: Request the driver to remain awake on the specified
1749 * channel for the specified duration to complete an off-channel
1750 * operation (e.g., public action frame exchange). When the driver is
1751 * ready on the requested channel, it must indicate this with an event
1752 * notification by calling cfg80211_ready_on_channel().
1753 * @cancel_remain_on_channel: Cancel an on-going remain-on-channel operation.
1754 * This allows the operation to be terminated prior to timeout based on
1755 * the duration value.
1756 * @mgmt_tx: Transmit a management frame.
1757 * @mgmt_tx_cancel_wait: Cancel the wait time from transmitting a management
1758 * frame on another channel
1760 * @testmode_cmd: run a test mode command
1761 * @testmode_dump: Implement a test mode dump. The cb->args[2] and up may be
1762 * used by the function, but 0 and 1 must not be touched. Additionally,
1763 * return error codes other than -ENOBUFS and -ENOENT will terminate the
1764 * dump and return to userspace with an error, so be careful. If any data
1765 * was passed in from userspace then the data/len arguments will be present
1766 * and point to the data contained in %NL80211_ATTR_TESTDATA.
1768 * @set_bitrate_mask: set the bitrate mask configuration
1770 * @set_pmksa: Cache a PMKID for a BSSID. This is mostly useful for fullmac

1773 * @del_pmksa: Delete a cached PMKID.
1774 * @flush_pmksa: Flush all cached PMKIDs.

1783 * @mgmt_frame_register: Notify driver that a management frame type was
1784 * registered. Note that this callback may not sleep, and cannot run
1785 * concurrently with itself.
1787 * @set_antenna: Set antenna configuration (tx_ant, rx_ant) on the device.
1788 * Parameters are bitmaps of allowed antennas to use for TX/RX. Drivers may
1789 * reject TX/RX mask combinations they cannot support by returning -EINVAL
1790 * (also see nl80211.h @NL80211_ATTR_WIPHY_ANTENNA_TX).
