e1000 with serdes only shows a fiber port

[Pierre Ossman <drzeus-list@drzeus.cx>]

Hi!

I'm having problems with the e1000 card in a Dell Poweredge 1855. This
model has support for both copper and fiber and has two cards on the PCI
bus (might supposed to be one for each type).

The problem is that both of these cards show only FIBER as a supported
port type, but I only have plain copper connectors attached to the
machine. There is no link detected at either end, except for a small
flicker just when the e1000 module is loaded.

The hardware doesn't seem to be the problem since it works nicely in
Windows on the same machine.

The device id of both controllers is 8086:107b, meaning SERDES. However,
if I look into e1000_ethtool.c:e1000_get_settings() I can see a test for
copper media, then and else assuming that the card is a fiber card.
Since this card can do both I'm guessing this code is broken.

I'm in rather desperate here since this is a blade server (i.e. no
chance of putting in another network card). :/
