mac80211: clean up rate control API
Long awaited, hard work. This patch totally cleans up the rate control API to remove the requirement to include internal headers outside of net/mac80211/. There's one internal use in the PID algorithm left for mesh networking, we'll have to figure out a way to clean that one up and decide how to do the peer link evaluation, possibly independent of the rate control algorithm or via new API. Additionally, ath9k is left using the cross-inclusion hack for now, we will add new API where necessary to make this work properly, but right now I'm not expert enough to do it. It's still off better than before. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
