Auto-Negociation fails between two Ethernet Marvell PHYs (88E1111)

The only way to connect two links directly together is with a crossover. You can either use a crossover cable, or for the Marvell PHY, you can manually enable the crossover within the PHY. I can't remember which register this is inside the PHY. I'll have to look for it tomorrow. If you go back in time (say Quartus 7.1) you may find the old MAC driver which I think would enable the crossover in the PHY automatically if it couldn't negotiate.
