+Subject: mac80211/drivers: rewrite the rate control API
+
+So after the previous changes we were still unhappy with how
+convoluted the API is and decided to make things simpler for
+everybody. This completely changes the rate control API, now
+taking into account 802.11n with MCS rates and more control,
+most drivers don't support that though.
