Configuration of additional ethernet adapters

[sinistergfx]

I use a USB gigabit ethernet adapter for faster file transfers on my Pi.
As it is right now, I have to edit /etc/network/interfaces manually to add an entry for eth1.

It would be nice if there was a way to configure this in dietpi.txt for automated installations and also in dietpi-config.

Additionally, the welcome screen doesn't display the ip address, probably because it's finding the on-board eth0 before eth1. Is there a way to completely disable eth0?
