Add support for PC-card router configuration. (MFPAO)
o Add the removable_interfaces variable for list of removable network interfaces (PC-card ethernet, wireless network and USB ethernet etc). o ifconfig_<ifn>_alias0, static_routes_<ifn>, removable_route_flush, /etc/start_if.<ifn> and /etc/stop_if.<ifn> are support. o removable_route_flush variable is set to "NO" if you want to use the machine as gateway using two or more removable network cards. If static routing is needed use static_routes_<ifn> instead of static_routes or defaultrouter. o The optional static_routes_<ifn> variable is likely static_routes. o /etc/start_if.<ifn> and /etc/stop_if.<ifn> are shell script to be specified that are called when a card is inserted or removed.
