More than ID changes, indeed. As layout is completely different, it
looks like different source file will be needed for support.
I'm not nearly there; but I can ifconfig lanX up, already, and perform
some pings.
Any ideas how to do the work in a way to minimize code duplication are
welcome...
Best regards,
Pavel
