>Description:
ndis does not work properly in BSS mode. It does not set associd.
Fake one because ndis doesnt yet support HOSTAP mode.
>How-To-Repeat:
# kldload ndis if_ndis bcmwl5.ko
# ifconfig wlan8 create wlandev ndis0
# ifconfig wlan8 ssid SSID
# ifconfig wlan8 up
# dhclient wlan0 <-- here it display following type of messages if wlan debug messages are enabled:
wlan0: [ff:ff:ff:ff:ff:ff] discard frame, sta not associated (type 0x0800)
wlan0: [ff:ff:ff:ff:ff:ff] discard frame, sta not associated (type 0x0806)
