Beware: You must create the new netdev in the wiphy\*(Aqs network namespace! Returns the struct wireless_dev, or an ERR_PTR\&. For P2P device wdevs, the driver must also set the address member in the wdev\&. .RE .PP del_virtual_intf .RS 4 remove the virtual interface .RE .PP change_virtual_intf .RS 4 change type/configuration of virtual interface, keep the struct wireless_dev\*(Aqs iftype updated\&. .RE .PP add_key .RS 4 add a key with the given parameters\&. \fImac_addr\fR will be \fBNULL\fR when adding a group key\&. .RE .PP get_key .RS 4 get information about the key with the given parameters\&. \fImac_addr\fR will be \fBNULL\fR when requesting information for a group key\&. All pointers given to the \fIcallback\fR 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\*(Aqt exist\&. .RE .PP del_key .RS 4 remove a key given the \fImac_addr\fR (\fBNULL\fR for a group key) and \fIkey_index\fR, return \-ENOENT if the key doesn\*(Aqt exist\&. .RE .PP set_default_key .RS 4 set the default key on an interface .RE .PP set_default_mgmt_key .RS 4 set the default management frame key on an interface .RE .PP start_ap .RS 4 Start acting in AP mode defined by the parameters\&. .RE .PP change_beacon .RS 4 Change the beacon parameters for an access point mode interface\&.

Note that flags changes are not much validated in cfg80211, in particular the auth/assoc/authorized flags might come to the driver in invalid combinations \-\- make sure to check them, also against the existing state! Drivers must call \fBcfg80211_check_station_change\fR to validate the information\&. .RE .PP get_station .RS 4 get station information for the station identified by \fImac\fR .RE .PP dump_station .RS 4 dump station callback \-\- resume dump at index \fIidx\fR .RE .PP add_mpath .RS 4 add a fixed mesh path .RE .PP del_mpath .RS 4 delete a given mesh path .RE .PP change_mpath .RS 4 change a given mesh path .RE .PP get_mpath .RS 4 get a mesh path for the given parameters .RE .PP dump_mpath .RS 4 dump mesh path callback \-\- resume dump at index \fIidx\fR .RE .PP get_mpp .RS 4 get a mesh proxy path for the given parameters .RE .PP dump_mpp .RS 4 dump mesh proxy path callback \-\- resume dump at index \fIidx\fR .RE .PP get_mesh_config .RS 4 Get the current mesh configuration .RE .PP update_mesh_config .RS 4 Update mesh parameters on a running mesh\&. The mask is a bitfield which tells us which parameters to set, and which to leave alone\&. .RE .PP join_mesh .RS 4 join the mesh network with the specified parameters (invoked with the wireless_dev mutex held) .RE .PP leave_mesh .RS 4 leave the current mesh network (invoked with the wireless_dev mutex held) .RE .PP join_ocb .RS 4 join the OCB network with the specified parameters (invoked with the wireless_dev mutex held) .RE .PP leave_ocb .RS 4 leave the current OCB network (invoked with the wireless_dev mutex held) .RE .PP change_bss .RS 4 Modify parameters for a given BSS\&. .RE .PP set_txq_params .RS 4 Set TX queue parameters .RE .PP libertas_set_mesh_channel .RS 4 Only for backward compatibility for libertas, as it doesn\*(Aqt implement join_mesh and needs to set the channel to join the mesh instead\&. .RE .PP set_monitor_channel .RS 4 Set the monitor mode channel for the device\&. If other interfaces are active this callback should reject the configuration\&. If no interfaces are active or the device is down, the channel should be stored for when a monitor interface becomes active\&. .RE .PP scan .RS 4 Request to do a scan\&. If returning zero, the scan request is given the driver, and will be valid until passed to \fBcfg80211_scan_done\fR\&. For scan results, call \fBcfg80211_inform_bss\fR; you can call this outside the scan/scan_done bracket too\&. .RE .PP abort_scan .RS 4 Tell the driver to abort an ongoing scan\&. The driver shall indicate the status of the scan through \fBcfg80211_scan_done\fR\&. .RE .PP auth .RS 4 Request to authenticate with the specified peer (invoked with the wireless_dev mutex held) .RE .PP assoc .RS 4 Request to (re)associate with the specified peer (invoked with the wireless_dev mutex held) .RE .PP deauth .RS 4 Request to deauthenticate from the specified peer (invoked with the wireless_dev mutex held) .RE .PP disassoc .RS 4 Request to disassociate from the specified peer (invoked with the wireless_dev mutex held) .RE .PP connect .RS 4 Connect to the ESS with the specified parameters\&. When connected, call \fBcfg80211_connect_result\fR/\fBcfg80211_connect_bss\fR with status code \fBWLAN_STATUS_SUCCESS\fR\&. If the connection fails for some reason, call \fBcfg80211_connect_result\fR/\fBcfg80211_connect_bss\fR with the status code from the AP or \fBcfg80211_connect_timeout\fR if no frame with status code was received\&. The driver is allowed to roam to other BSSes within the ESS when the other BSS matches the connect parameters\&. When such roaming is initiated by the driver, the driver is expected to verify that the target matches the configured security parameters and to use Reassociation Request frame instead of Association Request frame\&. The connect function can also be used to request the driver to perform a specific roam when connected to an ESS\&. In that case, the prev_bssid parameter is set to the BSSID of the currently associated BSS as an indication of requesting reassociation\&. In both the driver\-initiated and new \fBconnect\fR call initiated roaming cases, the result of roaming is indicated with a call to \fBcfg80211_roamed\fR or \fBcfg80211_roamed_bss\fR\&. (invoked with the wireless_dev mutex held) .RE .PP disconnect .RS 4 Disconnect from the BSS/ESS\&. (invoked with the wireless_dev mutex held) .RE .PP join_ibss .RS 4 Join the specified IBSS (or create if necessary)\&. Once done, call \fBcfg80211_ibss_joined\fR, also call that function when changing BSSID due to a merge\&. (invoked with the wireless_dev mutex held) .RE .PP leave_ibss .RS 4 Leave the IBSS\&. (invoked with the wireless_dev mutex held) .RE .PP set_mcast_rate .RS 4 Set the specified multicast rate (only if vif is in ADHOC or MESH mode) .RE .PP set_wiphy_params .RS 4 Notify that wiphy parameters have changed; \fIchanged\fR 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\&. .RE .PP set_tx_power .RS 4 set the transmit power according to the parameters, the power passed is in mBm, to get dBm use \fBMBM_TO_DBM\fR\&. The wdev may be \fBNULL\fR if power was set for the wiphy, and will always be \fBNULL\fR unless the driver supports per\-vif TX power (as advertised by the nl80211 feature flag\&.) .RE .PP get_tx_power .RS 4 store the current TX power into the dbm variable; return 0 if successful .RE .PP set_wds_peer .RS 4 set the WDS peer for a WDS interface .RE .PP rfkill_poll .RS 4 polls the hw rfkill line, use cfg80211 reporting functions to adjust rfkill hw state .RE .PP testmode_cmd .RS 4 run a test mode command; \fIwdev\fR may be \fBNULL\fR .RE .PP testmode_dump .RS 4 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 \fBNL80211_ATTR_TESTDATA\fR\&. .RE .PP set_bitrate_mask .RS 4 set the bitrate mask configuration .RE .PP dump_survey .RS 4 get site survey information\&. .RE .PP set_pmksa .RS 4 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\&. .RE .PP del_pmksa .RS 4 Delete a cached PMKID\&. .RE .PP flush_pmksa .RS 4 Flush all cached PMKIDs\&. .RE .PP remain_on_channel .RS 4 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 \fBcfg80211_ready_on_channel\fR\&. .RE .PP cancel_remain_on_channel .RS 4 Cancel an on\-going remain\-on\-channel operation\&. This allows the operation to be terminated prior to timeout based on the duration value\&. .RE .PP mgmt_tx .RS 4 Transmit a management frame\&. .RE .PP mgmt_tx_cancel_wait .RS 4 Cancel the wait time from transmitting a management frame on another channel .RE .PP set_power_mgmt .RS 4 Configure WLAN power management\&. A timeout value of \-1 allows the driver to adjust the dynamic ps timeout value\&. .RE .PP set_cqm_rssi_config .RS 4 Configure connection quality monitor RSSI threshold\&. After configuration, the driver should (soon) send an event indicating the current level is above/below the configured threshold; this may need some care when the configuration is changed (without first being disabled\&.) .RE .PP set_cqm_txe_config .RS 4 Configure connection quality monitor TX error thresholds\&. .RE .PP mgmt_frame_register .RS 4 Notify driver that a management frame type was registered\&. The callback is allowed to sleep\&. .RE .PP set_antenna .RS 4 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 \fINL80211_ATTR_WIPHY_ANTENNA_TX\fR)\&. .RE .PP get_antenna .RS 4 Get current antenna configuration from device (tx_ant, rx_ant)\&. .RE .PP sched_scan_start .RS 4 Tell the driver to start a scheduled scan\&. .RE .PP sched_scan_stop .RS 4 Tell the driver to stop an ongoing scheduled scan\&. This call must stop the scheduled scan and be ready for starting a new one before it returns, i\&.e\&. \fIsched_scan_start\fR may be called immediately after that again and should not fail in that case\&. The driver should not call \fBcfg80211_sched_scan_stopped\fR for a requested stop (when this method returns 0\&.) .RE .PP set_rekey_data .RS 4 give the data necessary for GTK rekeying to the driver .RE .PP tdls_mgmt .RS 4 Transmit a TDLS management frame\&. .RE .PP tdls_oper .RS 4 Perform a high\-level TDLS operation (e\&.g\&. TDLS link setup)\&. .RE .PP probe_client .RS 4 probe an associated client, must return a cookie that it later passes to \fBcfg80211_probe_status\fR\&. .RE .PP set_noack_map .RS 4 Set the NoAck Map for the TIDs\&. .RE .PP get_channel .RS 4 Get the current operating channel for the virtual interface\&. For monitor interfaces, it should return \fBNULL\fR unless there\*(Aqs a single current monitoring channel\&. .RE .PP start_p2p_device .RS 4 Start the given P2P device\&. .RE .PP stop_p2p_device .RS 4 Stop the given P2P device\&. .RE .PP set_mac_acl .RS 4 Sets MAC address control list in AP and P2P GO mode\&. Parameters include ACL policy, an array of MAC address of stations and the number of MAC addresses\&. If there is already a list in driver this new list replaces the existing one\&. Driver has to clear its ACL when number of MAC addresses entries is passed as 0\&. Drivers which advertise the support for MAC based ACL have to implement this callback\&. .RE .PP start_radar_detection .RS 4 Start radar detection in the driver\&. .RE .PP update_ft_ies .RS 4 Provide updated Fast BSS Transition information to the driver\&. If the SME is in the driver/firmware, this information can be used in building Authentication and Reassociation Request frames\&. .RE .PP crit_proto_start .RS 4 Indicates a critical protocol needs more link reliability for a given duration (milliseconds)\&. The protocol is provided so the driver can take the most appropriate actions\&. .RE .PP crit_proto_stop .RS 4 Indicates critical protocol no longer needs increased link reliability\&. This operation can not fail\&. .RE .PP set_coalesce .RS 4 Set coalesce parameters\&. .RE .PP channel_switch .RS 4 initiate channel\-switch procedure (with CSA)\&. Driver is responsible for veryfing if the switch is possible\&. Since this is inherently tricky driver may decide to disconnect an interface later with \fBcfg80211_stop_iface\fR\&. This doesn\*(Aqt mean driver can accept everything\&. It should do it\*(Aqs best to verify requests and reject them as soon as possible\&. .RE .PP set_qos_map .RS 4 Set QoS mapping information to the driver .RE .PP set_ap_chanwidth .RS 4 Set the AP (including P2P GO) mode channel width for the given interface This is used e\&.g\&. for dynamic HT 20/40 MHz channel width changes during the lifetime of the BSS\&. .RE .PP add_tx_ts .RS 4 validate (if admitted_time is 0) or add a TX TS to the device with the given parameters; action frame exchange has been handled by userspace so this just has to modify the TX path to take the TS into account\&. If the admitted time is 0 just validate the parameters to make sure the session can be created at all; it is valid to just always return success for that but that may result in inefficient behaviour (handshake with the peer followed by immediate teardown when the addition is later rejected) .RE .PP del_tx_ts .RS 4 remove an existing TX TS .RE .PP tdls_channel_switch .RS 4 Start channel\-switching with a TDLS peer\&. The driver is responsible for continually initiating channel\-switching operations and returning to the base channel for communication with the AP\&. .RE .PP tdls_cancel_channel_switch .RS 4 Stop channel\-switching with a TDLS peer\&. Both peers must be on the base channel when the call completes\&. .RE .SH "DESCRIPTION" .PP .PP This struct is registered by fullmac card drivers and/or wireless stacks in order to handle configuration requests on their interfaces\&. .PP All callbacks except where otherwise noted should return 0 on success or a negative error code\&. .PP 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\&. .SH "AUTHOR" .PP \fBJohannes Berg\fR <\&johannes@sipsolutions.net\&> .RS 4 Author. .RE .SH "COPYRIGHT" .br
