NAME
nameif - name network interfaces based on MAC addresses
SYNOPSIS
nameif [-c configfile] [-s]
nameif [-c configfile] [-s] {interface macaddress}
DESCRIPTION
nameif renames network interfaces based on mac addresses. When no argu-
ments are given /etc/mactab is read. Each line of it contains an
interface name and a Ethernet MAC address. Comments are allowed start-
ing with #. Otherwise the interfaces specified on the command line are
processed. nameif looks for the interface with the given MAC address
and renames it to the name given.

> Problem Description:
>
> When upgrading from 2.4.22 to 2.6.0, my three network cards (eth0, eth1, eth2)
> were renumbered. What was eth1 on 2.4 became eth2 on 2.6, and vice versa.
>
> This happens in a lot of other cases as well (order of SCSI drivers found, etc.)

>
> All three cards are 8193too cards.
>
> Steps to reproduce:
>
> Have three network cards using 8139too. Boot in 2.4, notice which physical card
> has which device name. Boot into 2.6, notice these are now switched.
