Description of problem:


The problem is that the bios for this machine is sending the same info for EVERY embedded device, see below for the output of udev to see the value of eno1 is being seen on each device. Unfortunately, there is no way to tell udev to use option 2 naming by default, so this makes the 1st embedded device to be named eno1, but every other interface will fail option 1-3 and end up being named the old standard eth0, eth1...

I've made a bit of a hack to my udev rules in order to ensure that the 2nd rule is used to name our interfaces, although this should not be necessary. I would like to see the bios remove it's interface naming so that udev uses rule 2 by default, much like many of our other SM hardware works.


output: Showing the BIOS sending name of eno1 to the kernel for each interface
[root@fdi ~]# udevadm info /sys/class/net/enp132s0f0 |grep ONBOARD
E: ID_NET_NAME_ONBOARD=eno1
[root@fdi ~]# udevadm info /sys/class/net/enp132s0f1 |grep ONBOARD

E: ID_NET_NAME_ONBOARD=eno1
[root@fdi ~]# udevadm info /sys/class/net/enp5s0f1 |grep ONBOARD
E: ID_NET_NAME_ONBOARD=eno1

output: current udev rules showing it using the ONBOARD name if it exists
[root@fdi ~]# cat /usr/lib/udev/rules.d/80-net-name-slot.rules

output: my hack to the ruleset to ensure that ONBOARD is skipped (I copied the rule into the "user" ruleset locale in etc, named it w/ a lower priority so that it is parsed before the built-in ruleset, and commented out the 1st rule)
