From: Johannes Berg <johannes.berg@xxxxxxxxx>
Instead of operating on a single channel only,
use the new channel context infrastructure in
all mac80211 code.
This enables drivers that want to use the new
channel context infrastructure to use multiple
channels, while nothing should change for all
the other drivers that don't support it.
