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

925 * and @key_index, return -ENOENT if the key doesn't exist.

977 * @leave_ibss: Leave the IBSS.
979 * @set_wiphy_params: Notify that wiphy parameters have changed;
980 * @changed bitfield (see &enum wiphy_params_flags) describes which values
981 * have changed. The actual parameter values are available in
982 * struct wiphy. If returning an error, no value should be changed.
984 * @set_tx_power: set the transmit power according to the parameters
985 * @get_tx_power: store the current TX power into the dbm variable;

997 * notification by calling cfg80211_ready_on_channel().
998 * @cancel_remain_on_channel: Cancel an on-going remain-on-channel operation.
999 * This allows the operation to be terminated prior to timeout based on
1000 * the duration value.
1002 * @testmode_cmd: run a test mode command
1004 * @set_pmksa: Cache a PMKID for a BSSID. This is mostly useful for fullmac
