Bug Description

Found on MOS 9.2 snapshot 688

Description:
for some network card interface renaming process fails, so some interfaces end up with name renameX.

The numbers seem to depend on NIC initialization order and this can cause deployment failure.

This issue is *not* reproduced neither with kernel 3.13 nor on MOS 10.0 (build 1237) kernel 4.4

To fix fcoe renaming the following file should be added to '/etc/udev/rules.d' - 80-fcoe-net-names-generator.rules (see attachement). IMPORTANT - it's index must be not lower than 75.

With this file network interfaces 'renameX' are renamed correctly to 'enp' intefaces:
-----
root@bootstrap:/etc/udev/rules.d# ip l
...
7: enp129s0f0: <BROADCAST,MULTICAST> mtu 2158 qdisc noop state DOWN mode DEFAULT group default qlen 1000
    link/ether 68:05:ca:30:01:c4 brd ff:ff:ff:ff:ff:ff
...
9: enp129s0f1: <BROADCAST,MULTICAST> mtu 2158 qdisc noop state DOWN mode DEFAULT group default qlen 1000
    link/ether 68:05:ca:30:01:c5 brd ff:ff:ff:ff:ff:ff
-----

So this could be fixed by custom udev rule added to /etc/udev/rules.d
