(Mostly) teach ath_rate_sample about MCS rates.

Browse Source 
This is just the bare minimum needed to teach ath_rate_sample to try
and handle MCS rates. It doesn't at all attempt to find the best
rate by any means - it doesn't know anything about the MCS rate
relations, TX aggregation or any of the much sexier 11n stuff
that's out there.

It's just enough to transmit 11n frames and handle TX completion.

It shouldn't affect legacy (11abg) behaviour.
