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.
