I had a quick chat with Johannes and Sujith about this. The concurrency
requirements are for the STA PS race in AP mode (see
ieee80211_handle_filtered_frame()).
I think we should drop this frame, revisit later and properly analyse
how to fix the race. But it would be good add this to the todo list:
