[Intel-wired-lan] Problem when igb is forced to 10-HD on both sides.

I think you need to read the IEEE spec on this. I'm still trying to figure out if 10-HD actually requires auto-MDI/MDI-X or if that's not covered.
I'm trying to find someone who remembers that far back. 10BASE-T is kind of historic at this time.

Hello,
Here is a related question:
Is there any way to make igb auto-negotiate at 10 and/or 100Mbps, but NOT 1Gbps?
For instance:
ethtool -s eth2 advertise 0x02
puts in into fixed 10-FD mode.
Thanks,
Ben
