Right, so that would mean you're clear regulatory wise to use the
entire 20 MHz for that channel. At a later time perhaps a custom
target bandwidth might be desired, then the regulatory bandwidth check
could be reduced. I'm not sure how we'll do this yet but if we keep
the bandwidth this lets us keep the max per channel and then easily
determine which smaller target bandwidths would be allowed.
