From: Johannes Berg <johannes.berg@xxxxxxxxx>
If allowed in a country, these channels typically require
DFS so mark them as such. Channel 144 is a bit special,
it's coming in use now to allow more VHT 80 channels, but
world roaming/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.
