Which version of wpa_supplicant are you using? Which network card and
driver are you using?
The EAPOL frame from the wired authenticator would be a multicast packet
and wpa_supplicant subscribes for that multicast group. It sounds like
something fails to deliver the frame to wpa_supplicant in this
particular case. Could you please test whether setting the interface
manually into promiscuous mode ("ifconfig eth0 promisc") would help? It
would also be interesting to see whether a packet sniffer (e.g.,
Wireshark or tcpdump) seems the EAPOL frame on the client.
