I should elaborate. Something like this code is needed, but right now
the regulatory database contains things like

        (5150 - 5350 @ 40), (N/A, 100 mW), NO-OUTDOOR, DFS

which means at most 40 MHz can be used.

In your patch, you don't even check this maximum bandwidth, which is a
bug, but even if you did the database would have to be changed.

Also, we probably really need to introduce handling of spectral power
limits to make this worthwhile?
