  Log:
  Phantom beacon miss workaround: track the tsf of the last received
  frame and if we get a beacon miss interrupt ignore it if we've received
  a frame within the beacon miss interval.  This should never trigger
  and the handling at the net80211 layer should likewise deal with this
  but it doesn't hurt and can suppress extranous probe request frames.
  Note that we can legtimately get a bmiss when under heavy load.
