mac80211: use rate index in TX control
This patch modifies struct ieee80211_tx_control to give band info and the rate index (instead of rate pointers) to drivers. This mostly serves to reduce the TX control structure size to make it fit into skb->cb so that the fragmentation code can put it there and we can think about passing it to drivers that way in the future. The rt2x00 driver update was done by Ivo, thanks. Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.
