Yes; you look at mshX and find the ethX device that has the same MAC
address to determine which ethX and mshX are actually the same hardware
underneath.

Ok, then ignore any ethX that comes from a marvell device and you'll be
fine.  NAT + route between the mshX and the normal ethernet wired card
on the machine.
