As I understand it on the Routerstation there are two ports on the AR7130 both of which are connected to the switch. eth0 is connected to the port on the switch which just connects to one external RJ54, the upstream WAN port, and then eth1 is connected to the two LAN RJ45s. For reference there is rather simple overview at http://ubnt.com/wiki/RouterStation.
So the idea would be to make the two LAN RJ45s individually configurable, as by default they operate quite well as a switch sharing a common config. It would also be useful to be able to sense link up/down transitions.
