This patch looks like it should be in the 3.9-stable tree, should we apply it? ------------------ From: "Moshe Benji <Moshe.Benji@xxxxxxxxx>" 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.
