o only include 1/2 and 1/4 width channels when they are specified in the regulatory database description; previously we treated them as if they were part of the band and blindly added them for 11a/g o check the channel list returned in the devcaps to identify whether a device supports 1/2 or 1/4 width channels on a band; this might be better brought out as a capability bit to avoid filling the channel list w/ 1/2 and 1/4 width channels but then cards that only support these channels in a range of frequencies could not be described (though right now we don't check frequency range only band)
