Just had a closer look at your log. wpa_supplicant is clearing keys 4
and 5, which is why you're getting invalid arguments reported. This
shouldn't affect driver behaviour.
After that, something seems to go wrong with scanning. Try a plain
scan with wpa_supplicant turned off. Do you get any results?
iw dev eth1 scan
iwlist eth1 scan
