This looks very odd.. There is not really any blocking operations in
wpa_supplicant between the places that print "WPA: Sending EAPOL-Key
2/4" and "WPA: TX EAPOL-Key"... How do you generate these syslog
messages? Could there be something buffering the TX EAPOL-Key message
and the delay would actually happen only after that? This could be
caused by send() getting blocked by something and the receiption of
deauthentication triggering unblocking somehow..
