Yes, we need to be able to start WPS negotiation with EAPOL state
machines if the STA sends an EAPOL-Start message. The previous version
worked by always starting the EAPOL state machines, but that did not
work with open mode (or static WEP for that matter). I fixed this by
moving the EAPOL state machine initialization to happen only when
receiving EAPOL-Start in this kind of configuration. That seems to
resolve the issue.
