Introduce NL80211_ATTR_TID_CONFIG_AMPDU_CTRL in nl80211_attr_tid_config to accept TID specific AMPDU aggregation enable/disable configuration through NL80211_CMD_SET_TID_CONFIG command. TID for which the aggregation control configuration is to be applied is passed in NL80211_ATTR_TID_CONFIG_TID attribute. When the user-space wants this configuration peer specific rather than being applied for all the connected stations, MAC address of the peer can be passed in NL80211_ATTR_MAC attribute.
Driver supporting this feature should advertise NL80211_EXT_FEATURE_PER_TID_AMPDU_CTRL and supporting per-STA data TID ampdu configuration should advertise NL80211_EXT_FEATURE_PER_STA_AMPDU_CTRL.
