From: Johannes Berg <[email protected]>
If allowed in a country, these channels typically require DFS
so mark them as such. Channel 144 is a bit special, it's coming
into use now to allow more VHT 80 channels, but world roaming
with passive scanning is acceptable anyway. It seems fairly
unlikely that it'll be used as the control channel for a VHT
AP, but it needs to be present to allow a full VHT connection
to an AP that uses it as one of the secondary channels.
Also enable VHT 160 on these channels, and also for channels
36-48 to be able to use VHT 160 there.

You guys all get a few more days for comments, then I'm merging this
next Monday. I really think it's the right thing to do, there's no
reason to prohibit passive scanning on radar channels that I know of.

So many months later ... I'm merging this now.
