  Maintain a history of data associated with received frames and use this to
  calculate smoothed signal quality data for each node.
  o add a 16-deep history buffer to each driver-private node storage that
    holds rssi and antenna info for received frames
  o override the default per-node "get rssi" method to return an average
    rssi value based on samples collected over the last second
  o enable beacon reception so even idle systems maintain a running history
    of signal quality
  This data may also be useful for improving the rate control algorithm.
  Based on work by Tom Marshall <tommy at> for MADWIFI.
