894 * @resume: wiphy device needs to be resumed
896 * @add_virtual_intf: create a new virtual interface with the given name,

898 * the new netdev in the wiphy's network namespace!
900 * @del_virtual_intf: remove the virtual interface determined by ifindex.

909 * @mac_addr will be %NULL when requesting information for a group
910 * key. All pointers given to the @callback function need not be valid
911 * after it returns. This function should return an error if it is
912 * not possible to retrieve the key, -ENOENT if it doesn't exist.

915 * and @key_index, return -ENOENT if the key doesn't exist.
917 * @set_default_key: set the default key on an interface
919 * @set_default_mgmt_key: set the default management frame key on an interface

926 * @del_beacon: Remove beacon configuration and stop sending the beacon.

938 * set, and which to leave alone.

942 * @change_bss: Modify parameters for a given BSS.
944 * @set_txq_params: Set TX queue parameters
946 * @set_channel: Set channel
948 * @scan: Request to do a scan. If returning zero, the scan request is given
949 * the driver, and will be valid until passed to cfg80211_scan_done().

955 * @deauth: Request to deauthenticate from the specified peer

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

967 * @leave_ibss: Leave the IBSS.
969 * @set_wiphy_params: Notify that wiphy parameters have changed;
970 * @changed bitfield (see &enum wiphy_params_flags) describes which values
971 * have changed. The actual parameter values are available in
972 * struct wiphy. If returning an error, no value should be changed.
974 * @set_tx_power: set the transmit power according to the parameters
975 * @get_tx_power: store the current TX power into the dbm variable;
976 * return 0 if successful

983 * @remain_on_channel: Request the driver to remain awake on the specified
984 * channel for the specified duration to complete an off-channel
985 * operation (e.g., public action frame exchange). When the driver is
986 * ready on the requested channel, it must indicate this with an event
987 * notification by calling cfg80211_ready_on_channel().
988 * @cancel_remain_on_channel: Cancel an on-going remain-on-channel operation.
989 * This allows the operation to be terminated prior to timeout based on
990 * the duration value.
992 * @testmode_cmd: run a test mode command
994 * @set_pmksa: Cache a PMKID for a BSSID. This is mostly useful for fullmac
995 * devices running firmwares capable of generating the (re) association
996 * RSN IE. It allows for faster roaming between WPA2 BSSIDs.
997 * @del_pmksa: Delete a cached PMKID.
