| /** |
| * 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 |

| * maintain a list itself. For this notification, various functions exist. |

| * on success or a negative error code. |
| * |
| * All operations are currently invoked under rtnl for consistency with the |
| * wireless extensions but this is subject to reevaluation as soon as this |
| * code is used more widely and we have a first user without wext. |
| * |
| * @suspend: wiphy device needs to be suspended. The variable @wow will |
| * be %NULL or contain the enabled Wake-on-Wireless triggers that are |
| * configured for the device. |
| * @resume: wiphy device needs to be resumed |
| * |
| * @add_virtual_intf: create a new virtual interface with the given name, |
| * must set the struct wireless_dev's iftype. Beware: You must create |
| * the new netdev in the wiphy's network namespace! Returns the netdev, |
| * or an ERR_PTR. |
| * |
| * @del_virtual_intf: remove the virtual interface determined by ifindex. |
| * |
| * @change_virtual_intf: change type/configuration of virtual interface, |
| * keep the struct wireless_dev's iftype updated. |
| * |
| * @add_key: add a key with the given parameters. @mac_addr will be %NULL |
| * when adding a group key. |
| * |
| * @get_key: get information about the key with the given parameters. |
| * @mac_addr will be %NULL when requesting information for a group |
| * key. All pointers given to the @callback function need not be valid |
| * after it returns. This function should return an error if it is |
| * not possible to retrieve the key, -ENOENT if it doesn't exist. |
| * |
| * @del_key: remove a key given the @mac_addr (%NULL for a group key) |
| * and @key_index, return -ENOENT if the key doesn't exist. |
| * |
| * @set_default_key: set the default key on an interface |
| * |
| * @set_default_mgmt_key: set the default management frame key on an interface |
| * |
| * @set_rekey_data: give the data necessary for GTK rekeying to the driver |
| * |
| * @add_beacon: Add a beacon with given parameters, @head, @interval |
| * and @dtim_period will be valid, @tail is optional. |
| * @set_beacon: Change the beacon parameters for an access point mode |
| * interface. This should reject the call when no beacon has been |
| * configured. |
| * @del_beacon: Remove beacon configuration and stop sending the beacon. |
| * |
| * @add_station: Add a new station. |
| * @del_station: Remove a station; @mac may be NULL to remove all stations. |
| * @change_station: Modify a given station. |

| * @leave_mesh: leave the current mesh network |
| * |
| * @get_mesh_config: Get the current mesh configuration |
| * |
| * @update_mesh_config: Update mesh parameters on a running mesh. |
| * The mask is a bitfield which tells us which parameters to |
| * set, and which to leave alone. |
| * |
| * @change_bss: Modify parameters for a given BSS. |
| * |
| * @set_txq_params: Set TX queue parameters |
| * |
| * @set_channel: Set channel for a given wireless interface. Some devices |
| * may support multi-channel operation (by channel hopping) so cfg80211 |
| * doesn't verify much. Note, however, that the passed netdev may be |
| * %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 |
| * @disassoc: Request to disassociate from the specified peer |
| * |
| * @connect: Connect to the ESS with the specified parameters. When connected, |
| * call cfg80211_connect_result() with status code %WLAN_STATUS_SUCCESS. |
| * If the connection fails for some reason, call cfg80211_connect_result() |
| * with the status from the AP. |
| * @disconnect: Disconnect from the BSS/ESS. |
| * |
| * @join_ibss: Join the specified IBSS (or create if necessary). Once done, call |
| * cfg80211_ibss_joined(), also call that function when changing BSSID due |
| * to a merge. |
| * @leave_ibss: Leave the IBSS. |
| * |
| * @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, |
| * the power passed is in mBm, to get dBm use MBM_TO_DBM(). |
| * @get_tx_power: store the current TX power into the dbm variable; |
| * return 0 if successful |
| * |
| * @set_wds_peer: set the WDS peer for a WDS interface |
| * |
| * @rfkill_poll: polls the hw rfkill line, use cfg80211 reporting |
| * functions to adjust rfkill hw state |
| * |
| * @dump_survey: get site survey information. |
| * |
| * @remain_on_channel: Request the driver to remain awake on the specified |
| * 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(). |
| * @cancel_remain_on_channel: Cancel an on-going remain-on-channel operation. |
| * 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. |
| * @set_power_mgmt: Configure WLAN power management. A timeout value of -1 |

| * @sched_scan_start: Tell the driver to start a scheduled scan. |
| * @sched_scan_stop: Tell the driver to stop an ongoing scheduled |
| * scan. The driver_initiated flag specifies whether the driver |
| * itself has informed that the scan has stopped. |
| * |
| * @mgmt_frame_register: Notify driver that a management frame type was |
| * 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). |
| * |
| * @get_antenna: Get current antenna configuration from device (tx_ant, rx_ant). |
| * |
| * @set_ringparam: Set tx and rx ring sizes. |
| * |
| * @get_ringparam: Get tx and rx ring current and maximum sizes. |
| * |

| * |
| * @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 |
