The issue with wpa_supplicant failing is due to the wlan0 interface
being cloned from one of the new usbus/usbpf devices instead of the
actual wireless network device:
brandon@m6500[/home/brandon]
$ ifconfig -v wlan0
wlan0: flags=1<UP> metric 0 mtu 0
nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL>
groups: usbus
How this might be happening is strange to me, how can the system be
confused as to which interface to clone from? Off-by-one error
somewhere?
