Well, it depends on how it's wired up.

The AR8316 (and other atheros switches) have an option to peel off one
of the ports as a dedicated PHY port, for situations where you have
two MACs on the SoC and you want to have a WAN port and multiple LAN
ports.

Theres three ways to do it:

* have one MAC port, map all switch ports to it, then peel off lan/wan
via VLAN ids
* have two MAC ports, have one port dedicated as a pass-through PHY
for the WAN port and the rest be switch ports for the LAN (vlan or
otherwise)
* a hybrid - have two MAC ports, and just map them using vlan ids or
per-port vlans as required.

So it boils down to whether the RB450G wires both arge interfaces to
the switch. If so, you can peel off a dedicated WAN PHY/port by
configuring up the 'phy4cpu' option in the hints file. Otherwise it's
vlans all the way down.
