On A-MPDU frames, the hardware only reports valid signal strength data for the last subframe. This patch fixes it by flagging everything but the last subframe in an A-MPDU to tell mac80211 to ignore the signal strength entirely. Otherwise the empty value (= 0 dbm) will distort the average quite badly.
