cfg80211: clean up signal type
It wasn't a good idea to make the signal type a per-BSS option, although then it is closer to the actual value. Move it to be a per-wiphy setting, update mac80211 to match. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
