This patch looks like it should be in the 3.9-stable tree, should we apply
it?

commit 622ebe994f6866b8d46ee5d3bcc329ed65d3722d upstream
Since driver does not use control.rates[0].count, we have never set that
variable. But currently, after rate control API rewrite, this is required
by mac80211. Otherwise legacy rates control does not work and we transmit
always at 1Mbit/s on pre 11n networks.
[same fix as for iwlegacy, thanks Stanislaw!]
