You should probably split this into cfg80211 and mac80211.

Also, this doesn't really seem to make a lot of _sense_ since nothing in
the kernel actually acts on detection of a color collision - hostapd is
acting on that.

So since you can easily make hostapd ignore the event, why do you even
need this?
