It's not a lot different from having to be in normal FCC regulations w/regard to
DFS channels, tx power, and such, but maybe having driver support is considered to make it
too easy for users to hack around restrictions?

Another part of this is that Cisco APs, at least, use fractional center
frequencies (4942.5, for instance) when using 5Mhz bandwidths on 4.9Ghz
channels, and that requires more patches that I don't think I even bothered
to post.

I'll keep this in my trees, someone needing it can just clone it and/or borrow
patches as needed.

Thanks,
Ben
