I guess it depends how they configure the filter. :)
If they really do the beacon/probe response filter thing then yes. For
b43, for instance, they also disable CFP updates etc. so aren't just
that. And you can get FIF_BCN_PRBRESP_PROMISC even while _not_ scanning,
due to monitor interfaces, so it really depends what they do (no CFP
disabling wanted then).
