nl80211/mac80211: Report signal average
Extend nl80211 to report an exponential weighted moving average (EWMA) of the
signal value. Since the signal value usually fluctuates between different
packets, an average can be more useful than the value of the last packet.
This uses the recently added generic EWMA library function.
