The EdgeRouter 4 (same Octeon target) uses a similar set-up; the PC 
Engines APU has a similar setup as well: 3 Ethernet ports, eth0 being 
set as WAN - see [2].

I can invert it and set eth2 as WAN port, if you'd like. The fallback 
setup for Octeon at this point is just as weird, to set eth0 as LAN 
(which is logical) and eth1 as WAN, and leave other ports unconfigured.

There's no perfect solution, but I think leaving a port unused makes 
even less sense than this.
