Description Narendra K 2010-10-12 10:04:28 UTC
Description of problem:

This feature is required to fix the issue of network interfaces not getting the
expected names. i.e eth0 does not map to the Integrated NIC 1 as labelled on
the server chassis.

System firmware communicates the firmware designated order of NICs to the OS
via SMBIOS type 41 device type instance. This is available to user space by
attribute 'index' as below - 

[root@libnet-test ~]# cat /sys/class/net/eth[2-5]/device/index
1
2
3
4

Udev should produce rules containing the attribute index to rename interface
with 1 to eth0, with index 2 to eth1 and so on. For ex: 

# This file was automatically generated by the /lib/udev/write_net_rules
# program, run by the persistent-net-generator.rules rules file.
#
# You can modify it, as long as you keep each rule on a single
# line, and change only the value of the NAME= key.

# PCI device 0x14e4:0x164c (bnx2) (custom name provided by external tool)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTRS{index}=="1",
ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"

# PCI device 0x14e4:0x164c (bnx2) (custom name provided by external tool)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTRS{index}=="4",
ATTR{type}=="1", KERNEL=="eth*", NAME="eth3"

# PCI device 0x8086:0x10c9 (igb) (custom name provided by external tool)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*",
ATTR{address}=="00:1b:21:54:33:3d", ATTR{type}=="1", KERNEL=="eth*",
NAME="eth5"

# PCI device 0x14e4:0x164c (bnx2) (custom name provided by external tool)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTRS{index}=="2",
ATTR{type}=="1", KERNEL=="eth*", NAME="eth1"

# PCI device 0x14e4:0x164c (bnx2) (custom name provided by external tool)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTRS{index}=="3",
ATTR{type}=="1", KERNEL=="eth*", NAME="eth2"

# PCI device 0x8086:0x10c9 (igb) (custom name provided by external tool)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*",
ATTR{address}=="00:1b:21:54:33:3c", ATTR{type}=="1", KERNEL=="eth*",
NAME="eth4"

Comment 4 Fedora End Of Life 2012-08-16 21:17:38 UTC
This message is a notice that Fedora 14 is now at end of life. Fedora 
has stopped maintaining and issuing updates for Fedora 14. It is 
Fedora's policy to close all bug reports from releases that are no 
longer maintained.  At this time, all open bugs with a Fedora 'version'
of '14' have been closed as WONTFIX.

(Please note: Our normal process is to give advanced warning of this 
occurring, but we forgot to do that. A thousand apologies.)

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, feel free to reopen 
this bug and simply change the 'version' to a later Fedora version.

Bug Reporter: Thank you for reporting this issue and we are sorry that 
we were unable to fix it before Fedora 14 reached end of life. If you 
would still like to see this bug fixed and are able to reproduce it 
against a later version of Fedora, you are encouraged to click on 
"Clone This Bug" (top right of this page) and open it against that 
version of Fedora.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events.  Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

The process we are following is described here:
