Yes, "ethernetif" is sort of the generic name used in the skeleton,
internals for a netif belong to the developer (that's the reason for my
'driveroutputfunction' comment on that line).
Well, if I'm not missing something important, it looks like you have a
problem on the driver/wire side. Try to find a good old Ethernet hub or
a modern switch with monitor capabilities to sniff what is going on in
the wire, if anything.
PS: Yes, I do have a couple spare hubs I did save for this reason...
