Promiscuous mode has number of issues and the exact behavior may depend
on the used STA firmware version. This issue with RTS/CTS may be one of
those issues..

Who knows.. I've given up on trying to do anything with promiscuous mode
with Prism2/2.5/3 cards. This would be a question for whoever is
maintaining the firmware (if anyone) at this point. Though, I would not
expect to get any answer.
