mac80211: notify driver of rate control updates
Devices that have internal rate control need to be notified when the bandwidth or SMPS state changes just like external rate control algorithms get a notification now. Add this notification and clarify the change bits while at it, the HT_CHANGED bit really meant only bandwidth changed. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: John W.
