Hi Anton,
Here's the output you requested. I also have a dual 10G card on these
servers too, I've included the output for them too for completeness.

Hello, Kieran.
I saw quiet the same behaviour on Asus motheboards with integrated 82574 NIC.
The same as Supermicro (82576) wiring will lead to different interface name in
Linux. On Asus we usually have first LAN as eth1 and second LAN as eth0.
Supermicro has proper correlation: eth0 for LAN1 and eth1 for LAN2.
What model of mobo has you?
Could you please provide the output of the following commands:
# lspci -nn | fgrep 0200
# ethtool -i eth0
# ethtool -i eth1

Hi,
I have several servers withe Intel 82576 Dual Port Gigabit NICs in them.
I currently have only one port from each wired up to the network, and
the other empty. I can get iPXE to boot, and it'll get a DHCP link and
do it's thing.
The problem is, iPXE will boot from nic0 with MAC address
XX:XX:XX:XX:XX:0d, but once in linux, trying to run dhclient on the
interface that has that MAC address fails. ethtool claims no link.
Running dhclient on the interface XX:XX:XX:XX:XX:0c succeeds however. 0c
is the interface iPXE claims to be net1, which it is unable to get a
link on.
I'm using the onboard PXE boot environment to chainload iPXE. The
onboard PXE gets a link and loads iPXE through the 0c interface,
followed by iPXE getting a link on the 0d interface, followed by Linux
being able to get a link on 0c again.
I believe this problem may be linked to point 5 in this FAQ[1] relating
to the 82580
Are the MAC Addresses still automatically calculated like on the 82576?
So my guess is that the MAC Addresses are calculated when the driver
loads, and some difference between the way the BIOS, iPXE and Linux
drivers work causes the interfaces to be enumerated in different orders.
This is an issue as trying to pass anything like BOOTIF to get
installers and such to use the correct interface to install from doesn't
work.
Output from ifstat if needed:
