AP power save feature is enabled when the driver and hardware supports. If the driver suppots this feature then driver will advertise this flag SUPPORTS_AP_PS to enable the AP power save in mac80211. AP goes into the power save mode, if no stations are connected and it will come out of power save as and when any of the station associate to it. Also, during the power save tx chain mask is reduced to 1x1 until the any station connects with more than 1x1 chain mask. Rename NL80211_CMD_SET_BEACON to NL80211_UPDATE_AP to make use of this command to configure more AP parameters which can vary at the run time of the BSS like AP power save config. A new nl80211 attribute NL80211_ATTR_AP_PS is introduced for this AP power save configuration from user space which is used along with the NL80211_CMD_UPDATE_AP.
