Hi!
this version works fine, but there is a null pointer exception after some loads/unloads. i tried the following test script with 2 prism2.5 pci cards and the kernel segfaulted after about 12 cycles:
CARDS="0 1" for i in $(seq 1 100);
do echo "[($i)]:";
modprobe hostap_pci;
for j in $CARDS; do echo "[wlan$j]";
ifconfig wlan$j up;
iwconfig wlan$j essid WaveHAN$j;
ifconfig wlan$j down;
done;
modprobe -r hostap_pci;
i tried it again with the following patch and it worked without problems (ok, i don't tested more than 100 cycles):
