-/**
- * 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.

- * channels to scan, and the SSIDs to send probe requests for (including the

- * in the wiphy structure.
- *
- * When scanning finds a BSS, cfg80211 needs to be notified of that, because
- * it is responsible for maintaining the BSS list; the driver should not
- * maintain a list itself. For this notification, various functions exist.
- *
- * Since drivers do not maintain a BSS list, there are also a number of

- * BSS structure cfg80211 maintains. The BSS list is also made available

- * @set_txq_params: Set TX queue parameters
- *
- * @set_channel: Set channel for a given wireless interface. Some devices

- * %NULL as well if the user requested changing the channel for the
- * device itself, or for a monitor interface.
- * @get_channel: Get the current operating channel, should return %NULL if
- * there's no single defined operating channel if for example the
- * device implements channel hopping for multi-channel virtual interfaces.
- *
- * @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.
- *
- * @auth: Request to authenticate with the specified peer
- * @assoc: Request to (re)associate with the specified peer
- * @deauth: Request to deauthenticate from the specified peer

- *
- * @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

- * 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().

- * 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
- * @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.

- * registered. Note that this callback may not sleep, and cannot run
- * concurrently with itself.
- *
- * @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).

- * @WIPHY_FLAG_CUSTOM_REGULATORY: tells us the driver for this device
- * has its own custom regulatory domain and cannot identify the
- * ISO / IEC 3166 alpha2 it belongs to. When this is enabled
- * we will disregard the first regulatory hint (when the
- * initiator is %REGDOM_SET_BY_CORE).
- * @WIPHY_FLAG_STRICT_REGULATORY: tells us the driver for this device will
- * ignore regulatory domain settings until it gets its own regulatory
- * domain via its regulatory_hint() unless the regulatory hint is
- * from a country IE. After its gets its own regulatory domain it will
- * only allow further regulatory domain settings to further enhance
- * compliance. For example if channel 13 and 14 are disabled by this
- * regulatory domain no user regulatory domain can enable these channels
- * at a later time. This can be used for devices which do not have
- * calibration information guaranteed for frequencies or settings
- * outside of its regulatory domain.
- * @WIPHY_FLAG_DISABLE_BEACON_HINTS: enable this if your driver needs to ensure
- * that passive scan flags and beaconing flags may not be lifted by
- * cfg80211 due to regulatory beacon hints. For more information on beacon
- * hints read the documenation for regulatory_hint_found_beacon()
- * @WIPHY_FLAG_NETNS_OK: if not set, do not allow changing the netns of this
- * wiphy at all
- * @WIPHY_FLAG_ENFORCE_COMBINATIONS: Set this flag to enforce interface
- * combinations for this device. This flag is used for backward
- * compatibility only until all drivers advertise combinations and
- * they will always be enforced.
- * @WIPHY_FLAG_PS_ON_BY_DEFAULT: if set to true, powersave will be enabled
- * by default -- this flag will be set depending on the kernel's default
- * on wiphy_new(), but can be changed by the driver if it has a good
- * reason to override the default
- * @WIPHY_FLAG_4ADDR_AP: supports 4addr mode even on AP (with a single station
- * on a VLAN interface)
- * @WIPHY_FLAG_4ADDR_STATION: supports 4addr mode even as a station
- * @WIPHY_FLAG_CONTROL_PORT_PROTOCOL: This device supports setting the
- * control port protocol ethertype. The device also honours 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_SUPPORTS_SCHED_SCAN: The device supports scheduled scans.
- * @WIPHY_FLAG_SUPPORTS_FW_ROAM: The device supports roaming feature in the
- * firmware.
- * @WIPHY_FLAG_AP_UAPSD: The device supports uapsd on AP.
- * @WIPHY_FLAG_SUPPORTS_TDLS: The device supports TDLS (802.11z) operation.
- * @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_HAVE_AP_SME: device integrates AP SME
- * @WIPHY_FLAG_REPORTS_OBSS: the device will report beacons from other BSSes
- * when there are virtual interfaces in AP mode by calling
- * cfg80211_report_obss_beacon().
- * @WIPHY_FLAG_AP_PROBE_RESP_OFFLOAD: When operating as an AP, the device
