mac80211: deprecate RX status noise
The noise value as is won't be used, isn't filled by most drivers and doesn't really make a whole lot of sense on a per packet basis -- proper cfg80211 survey support in mac80211 will need to be different. Mark the struct member as deprecated so it will be removed from drivers. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
