2nd NIC named dev### instead of eth1

[Paul Raines]

We added a 2nd E1000 gig card to a box with Fedora Core 2 running
the 2.6.6-1.435smp kernel.  Instead of coming up as eth1 it comes
up as dev### where ### is a random number that changes each boot.


# lspci | grep thernet

(rev 02)

# cat /proc/net/dev | cut -d: -f1 | tail +3
     lo
dev265
   eth0

# ifconfig dev265

I can configure it with IP info and it works as ifconfig above shows.
I can create a /etc/sysconfig/network-scripts/ifcfg-dev265 for it.
But since the number changes randomly each boot, I have to do this
by hand every boot.

Why does it not come up as eth1? The kernel messages seem to refer to
eth1:

# dmesg | grep eth
divert: not allocating divert_blk for non-ethernet device lo
e1000: eth0: e1000_probe: Intel(R) PRO/1000 Network Connection
divert: allocating divert_blk for eth0
e1000: eth1: e1000_probe: Intel(R) PRO/1000 Network Connection
divert: allocating divert_blk for eth1
divert: freeing divert_blk for eth0
divert: freeing divert_blk for eth1
