When using wpa_supplicant in -D ndis mode, it modifies the interface
configuration directly using ioctl()s to the NDIS driver (which is
exactly what it does on Windows, only in Windows it's called
DeviceIoControl() instead of ioctl). Consequently, net80211 isn't
aware of all the state changes that it triggers. I think this can
be remedied, but for now I thought people would be more interested
in actually having WPA and WPA2 actually work, and wouldn't mind so
much that ifconfig didn't always report precisely the right state
info at all times.
I can probably fix this, but it'll have to wait until after the
release is cut before I can merge it into 6.x.
Out of curiosity, what card do you have?
