 Testing a D-Link WBR-2310 in WPA mode. Authentication completes,
 association too, but WPA PTK/GTK handshake fails.

 There are 4 handshake messages as usual (supplicant, authenticator,
 supplicant, authenticator) at which point the PTK is installed. It then
 enters group handshake mode but wpa_supplicant does not see the next
 EAPOL.

 I ran a system in monitor mode next to it and confirmed that the AP did
 send the 5th EAPOL. It did not retransmit it, suggesting that it also
 received acknowledgement (my monitor does not show acks). So the message
 is being lost somewhere.

 Interestingly, it is timing-sensitive too. If I run wpa_supplicant in
 verbose mode on the XO console, the extra delay imposed by printing a lot
 of messages results in WPA PTK+GTK completing. Odd.
