Our Cisco AP's set key index 3 for the PTK. This patch removes the check
for the key index. I also tried to set idx=0 by hand, but this did not
work (presumably because the AP then discarded my unicast packets with
key index 0 instead of 3).
With these two patches I can successfully use our dynamic wep wireless
network.
