Sounds exactly like you have a new Intel EtherExpress Pro/10+ card
with one of the new hardware addresses. Unfortunately, the ex driver
uses the hardware address to decide if the card is a Pro/10 or a
Pro/10+, and I'm not capable of coming up with a better solution. So I
just added the check for an Ethernet address prefix of 00:90:27 in
addition to the existin check of a 00:A0:C9 prefix.

Nope. :(

Well, it depends on the hardware address of your card. If the ethernet
address of your Pro/10+ NIC starts with 00:90:27 I'd expect my patch
to work. If it doesn't, you'll either have to tweak the patch, or give
me the prefix and I can tweak it for you.

If it isn't the same as what I had, and I expect that it is, then I'm
clueless. :)
Brad> 2) This is just to satisfy my own curiousity, but exactly what
Brad> would I be doing by changing this stuff in the drivers?
You would change the ex driver to recognize additional hardware
addresses as a Pro/10+ card.
Hope this helps. Here is the patch:
