[Linux-cluster] AoE does not discover

I am using a Tyan Thunder 2881 mobo with kernel 2.6.10... It has two onboard
broadcom gigabit nics that use built in driver module tg3.

Right, it seems to be not talking on the network.

I have directly connected a machine to the machine that should be doing the
aoe broadcast and I run tethereal on it and it sees nothing.

I am thinking maybe my hardware is messed up somehow. I have AoE working
properly from my disk node to my desktop workstation so I know the
technology works and that I have the server set up properly.

The server that cannot discover AoE devices is using a Tyan S2882-D Thunder
K8SD Pro motherboard. Anyone know what ethernet drivers I should be using
with this? It is very strange. It has two gigabit network ports. I
understand it has a Broadcom gigabit chipset. But apparently it also has an
Intel eepro10/100 chipset...maybe on only one of the ports. 
It is not clear. I cannot find any docs anywhere that explain this clearly.
I originally booted it with the eepro10/100 chipset and that detected a
network interface, but only one. And it did not seem to be able to do AoE
discovery over that interface for whatever reason. I removed the intel
driver and compiled the Broadcom NetXtreme II driver into the kernel and it
did not detect any ethernet devices at all.

Is anyone using one of these boards? Care to tell me what driver you are
using or exactly what kind of ethernet chipset it really has?
