/*
2008-12-16, For Corega CG-WLCB54GL 54Mbps NIC interoperability issue.
The behavior of this NIC when it connect to the other AP with WPA/TKIP is:
AP <----------------------> STA
....................
------------> Assoc Rsp (ok)
------------> EAPOL-key (4-way msg 1)
<------------ unknown TKIP encryption data
------------> EAPOL-key (4-way msg 1)
<------------ unknown TKIP encryption data
.....................
<------------ disassoc (code=8, STA is leaving) when the 5 seconds timer timeout counting from Assoc_Rsp is got.
....................
------------> Assoc Rsp (ok)
<-----------> EAPOL-key (4-way handshake success)
If MAX_RESEND_NUM=3, our AP will send disassoc (code=15, 4-way timeout) to STA before STA sending disassoc to AP.
And this NIC will always can not connect to our AP.
set MAX_RESEND_NUM=5 can fix this issue.
