In the batman-adv module (which implements a routing protocol for mesh networks
on layer 2) we are trying to switch metric from packet loss to throughput and
the idea is to read the estimation from the rate control component (thanks to
the API mechanism in cfg/mac80211 this can be eventually changed later).

I am not entirely sure that the value I proposed to read (the maximum in the
rate table) is the one which better plays the needed role. But the preliminar
tests demonstrated that it  :)
