Allowing station to over-ride default VHT-oper element?

[Ben Greear <greearb@candelatech.com>]

I'm trying to figure out how to make a VHT station with hardware capable
of 80Mhz width instead force itself to advertise/use just 40Mhz width,
but still support VHT.

Similar to how the VHT-capabilities overrides works, but for
VHT-operation.

First, is this even a valid thing to do, or does VHT imply
that stations are always available to do 80Mhz?

And second, if it is a valid thing to do, any hints on a
proper way to go about this.  I'm getting a bit tangled in
the code trying to figure out where to apply any overloads
properly.

Possibly in ieee80211_determine_chantype?

Thanks,
Ben
