I did not find any clear indication from the debug log other than
something being wrong and whatever it is, is likely outside the scope of
wpa_supplicant functionality.

This would require debugging at the driver level (which may be difficult
in this case) or at least taking a look with a wireless sniffer to check
whether the EAPOL frames are being sent properly (i.e., whether they are
lost somewhere since wpa_supplicant does not see them) or whether there
could be some low-level issues that prevent them from being transmitted.
