True, the ordering is not exactly the same everytime. One will need to
provide PCI Bus related info also to a practical udev configuration to
get things sorted out in a sane way, rather than anything else.
At least in Mandriva, the order and naming of network adapters are
handled by using a this kind of udev rule which prevents for example eth0
and eth1 to swap between boots:
[lamikr@iiris rules.d]$ cat 70-persistent-net.rules
# 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.
# Drakx-net rule for eth0 (00:24:e8:9e:66:13)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*",
ATTR{address}=="00:11:22:33:44:55", ATTR{type}=="1", KERNEL=="eth*",
NAME="eth0
# PCI device 0x8086:0x4232 (iwlagn)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*",
ATTR{address}=="11:22:33:44:55:66", ATTR{type}=="1", KERNEL=="wlan*",
NAME="wlan0""
I am not sure whether udev rules itself can originally generate this file
or whether it's mandriva's own tools/scripts that will generate this file
and add all new adapters it finds that are not yet in the file.
