Yes it works with our 12xx, in the 12xx the FW (upon channel switch

So ... you've made this kind of behaviour a mandatory part of the
userspace API. Where is it documented then? How will it work with other
devices?
It's should work the same with other devices, each device should
implement AP channel switch op according the spec, the implementation
can be hardware/driver depended. I just mentioned how we do it in our
devices, which I think is the right way without introducing any races
(as you mentioned), So no behavior enforcement here as long as it
according the spec.
I don't think that's how it works ... you should describe what is
expected of the driver in the right API documentation. Even saying
"implement the procedures as described in 802.11-2012 section ..." could
be sufficient, but I think that needs to be there.
np, I can add it.
