I think you currently have tested this with PPP / Ethernet? Do you just
have an Idea how much has to be changed to be able to register two
Ethernet interfaces?

We definitely will have adapt the PHY registration in a way that a PHY
is assigned to each Ethernet driver instance and not handled global (as
it currently is).

Great work! 


PS: Do you have an idea, how much effort and resources would be needed
to implement NAT?
