Subject: ieee80211_radar_status?

Hi,

Is there any documentation for the arguments to ieee80211_radar_status?
I don't see anything in the header files and drivers nor any use in
wpa_supplicant and hostapd.

When moving to nl80211, this shall be handled there, but since we don't
have anybody using it right now we might as well kill it off completely
until we need it (again).

Huh, ok, but why were the arguments added then. Oh well, doesn't matter
much.

Yeah, true, but unless I see something using it I don't think I can
properly define the semantics for the nl80211 message, and thus I can't
define the semantics for cfg80211, and then not for the function that
the low-level driver calls...

Apparently not. It looks like it was only used for reporting a detected
radar and none of the arguments were really used, i.e., it is just a
callback from low-level driver to notify if a radar was detected on the
current channel.

This function is called by low-level driver and it would not have
anything to do with nl80211.. The ieee80211_msg_radar type message to
user space would be the one that would need to be replaced.
