As a matter of fact QCA6174 firmware does seem to work with IBSS as
well. I just found out (by accident, after leaving a failed test setup
for a while) that after approx. 300 seconds firmware discards all
stuck EAPOL frames and starts sending subsequent ones properly. Keys
gets exchanged, installed and traffic seems to work fine with this
patchset. I suppose this warrants an updated commit log.
