I suppose if you reject the NEW_STATION command, then hostapd will
reject the association though, so it's probably not hard to do.
However, I'm not really sure why you'd want that? If you do want that
then basically you're just implemented a very roundabout way of adding
this rate to the basic rates, so you might as well just add it and work
with the current basic rates check?


We'll need to be a little careful what happens with client-mode
interfaces, which is where we actually observed hitting the WARN_ON()
about not having any rates at all, but I think I already put a reset of
the rates there anyway if they're not compatible with the AP. At least
that's easier because there's only one client.
