961 | * the scan/scan_done bracket too. |
962 | * |
963 | * @auth: Request to authenticate with the specified peer |
964 | * @assoc: Request to (re)associate with the specified peer |
965 | * @deauth: Request to deauthenticate from the specified peer |
966 | * @disassoc: Request to disassociate from the specified peer |
967 | * |
968 | * @connect: Connect to the ESS with the specified parameters. When connected, |
969 | * call cfg80211_connect_result() with status code %WLAN_STATUS_SUCCESS. |
970 | * If the connection fails for some reason, call cfg80211_connect_result() |
971 | * with the status from the AP. |
972 | * @disconnect: Disconnect from the BSS/ESS. |
973 | * |
974 | * @join_ibss: Join the specified IBSS (or create if necessary). Once done, call |
975 | * cfg80211_ibss_joined(), also call that function when changing BSSID due |
976 | * to a merge. |
977 | * @leave_ibss: Leave the IBSS. |
978 | * |
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. |
983 | * |
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; |
986 | * return 0 if successful |
987 | * |
988 | * @rfkill_poll: polls the hw rfkill line, use cfg80211 reporting |
989 | * functions to adjust rfkill hw state |
990 | * |
991 | * @dump_survey: get site survey information. |
992 | * |
993 | * @remain_on_channel: Request the driver to remain awake on the specified |
994 | * channel for the specified duration to complete an off-channel |
995 | * operation (e.g., public action frame exchange). When the driver is |
996 | * ready on the requested channel, it must indicate this with an event |
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. |
1001 | * @action: Transmit an action frame |
1002 | * |
1003 | * @testmode_cmd: run a test mode command |
1004 | * |
1005 | * @set_pmksa: Cache a PMKID for a BSSID. This is mostly useful for fullmac |
1006 | * devices running firmwares capable of generating the (re) association |
1007 | * RSN IE. It allows for faster roaming between WPA2 BSSIDs. |
1008 | * @del_pmksa: Delete a cached PMKID. |
