By using udev rules like following, I am able to align what shows in 
BIOS to what is being configured by kernel, ie. NIC1 --> eth0, NIC2 --> 
eth1.  eth0 worked fine.
This is before I started xend though.

Once xend starts, eth0 no longer worked. It could reach out to anywhere 
from eth0.  I found someone said workaround is to disable IMPI feature 
in the NIC firmware. But they seems running into some stability problem. 
I am just wondering if such problem has been fixed by upgrading to newer 
BIOS?


# PCI device 0x14e4:0x164c (bnx2)
SUBSYSTEM=="net", DRIVERS=="?*", ATTRS{address}=="xx:xx:xx:xx:xx:d4", 
NAME="eth0"

# PCI device 0x14e4:0x164c (bnx2)
SUBSYSTEM=="net", DRIVERS=="?*", ATTRS{address}=="xx:xx:xx:xx:xx:d6", 
NAME="eth1"
