This is only for tests purpose and should not be enabled in production code.
Main idea is to use wpaspy (patch 6/6) and run tests using machines
from local network. Currently there are a hwsim tests, which are used
for wpa_supplicant/hostapd testing.
In the future I think about testing whole stack also -
wpa_supplicant/hostapd + driver + hw. And for that using UDP version
of wpaspy + wpa_supplicant/hostapd with CTRL UDP iface.
