ARC SDP board sports only 1 network interface - eth0,
so to operate as an access point it requires at least
another interface (preferably wireless),
so USB Wi-Fi dongle is what we want.
And with USB Wi-Fi dongle attached ARC SDP board could be
used as a "dumb" wireless access point.
Now with modified network setup script it is only required
to enable wireless radio on the first boot with
-------------->8------------
uci set wireless.radio0.disabled=0
uci commit wireless
wifi
-------------->8------------
Note if by the time initscripts are executed USB Wi-Fi
dongle not yet recognized and set up by Linux kernel
its autodetection by "wifi" tool may not happen
automatically. In that case before issuing command above
one needs to populate /etc/config/wireless config:
-------------->8------------
wifi detect > /etc/config/wireless
-------------->8------------
