Technically speaking since some countries do not support
some channels in 5 GHz the world regulatory domain should not
use them however APs should *not* be shipped in those countries
which don't allow 5 GHz operation. Because of this we can
safely assume we operate correctly in STA mode by forcing
passive scan and disabling ad-hoc in 5 GHz. We leave out
all DFS channels as we don't support DFS yet.
