Hi,
After replacing the mainboard on a HP ML350G5 server the NIC port on the mainboard suddenly no
longer shows up as the first NIC eth0.
I assumed it was because udev reserved eth0 for the old NIC so I deleted the
/etc/udev/rules.d/70-persistent-net.rules file, rebooted the server and expected everything to be
ok. It was not.
Strangely the NIC on the mainboard did not show up as the last ethX port either. I have an extra NIC
card with 4 ports in that server and the mainboard port shows up in the midle. :-(
So port A and B of the PCI card are eth0 and eth1, the NIC on the mainboard is eth2, and port C and
D on the PCI card are eth3 and eth4.
The NIC on the mainboard is a Broadcom NetXtreme, the 4 extra ports are Intel
based.

Can anyone explain why this is happening?
Unfortunately I don't have the old dmesg files to see what was happening before the mainboard was
replaced.
By editing the /etc/udev/rules.d/70-persistent-net.rules file I was able to get everything as it was
supposed to be and get the firewall script propery running. Thank God for udev. ;-)
