76  * DOC: station table - introduction
78  * The station table is a list of data structure that reprensent the stations.
79  * In STA/P2P client mode, the driver will hold one station for the AP/ GO.
81  * All these stations are reflected in the fw's station table. The driver
82  * keeps the fw's station table up to date with the ADD_STA command. Stations
85  * All the data related to a station is held in the structure %iwl_mvm_sta
87  * This data includes the index of the station in the fw, per tid information
93  * station index. That way, the driver is able to get the tid related data in

147  * %iwl_mvm_vif includes the index of the AP station in the fw's STA table:
150  * the AP station from the fw before setting the MAC context as unassociated.
151  * Hence, %fw_id_to_mac_id[%ap_sta_id] will be NULLed when the AP station is

163  * Drain means that the fw will drop all the frames sent to a specific station.
168  * DOC: station table - fw restart
187  * When a station is asleep, the fw will set it as "asleep". All frames on

203  * When we receive a frame from that station with PM bit unset, the driver
204  * needs to let the fw know that this station isn't asleep any more. This is
