But mac80211 doesn't wait for a switch to happen. It removes the BSS and station
info immediately after sending the deauth frame to the driver and the driver doesn't
get a chance to process the pending frames for the other context. I think
this race could be avoided by making sure the driver switches to the
required context before sending deauth.
