To: John Linville; +Cc: linux-wireless
This patch reworks the mac80211 debug settings making them more focused
and adding help text for those that didn't have one. It also removes a
number of printks that can be triggered remotely and add no value, e.g.
"too short deauthentication frame received - ignoring".
If somebody really needs to debug that they should just add a monitor
interface and look at the frames in wireshark.
