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

commit a8cf0194b7187fb65dfff28a1c5153d442e3836a 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.

mac80211: improve the rate control API
which first appear on 3.10-rc2. Sorry for not specifying that information
in the ChangeLog.
