Why does supplicant lose the SSID?

[Sriharsha Vedurmudi]

Friends,
 The supplicant is losing the SSID (after associating with the AP)
when it is trying to process the received EAPOL frame 1/4. I get the
message:
WPA: No SSID info found (msg 1 of 4).
The code shows that when the state machine has NULL for SSID, this
comes up. Under what circumstances will the state machine lose the
SSID info after association? I am trying to write a driver, using
driver_wext, to test WPA-PSK feature of a new upcoming chip.
The access point is sending the first EAPOL frame 4 times (in which
one or two times the FCS check fails) and then disassociating the sta.

Here is the dump for clarity:

Please let me know if anyone has any idea why this is happening.
