Also, if you could make sure this stuff is completely separate
conceptually and architecturally from mac80211 itself, but have mac80211
_rely_ on it, then we can rip the bits out of the fullmac drivers that
do regdomain stuff and plug them into this framework too.  I think
that's a real win.  There's not a pile of code in the fullmac drivers
for this, but there's enough that it sucks having to have these defines
all over the place.

Also having somewhere that has standard functions that map channels to
frequencies and back would rock (if you do, please use u32 here for
frequencies not floats of course, like 2412000 and such unless you think
u64 would work better to specify down to the single Hz level).
