Bug#890986: BIOS upgrade change main ethernet device name / regression from previous debian versions

[Laurent GUERBY]

Package: udev
Version: 232-25+deb9u1
Severity: normal

On a Asrock AB350 Gaming K4 motherboard based machine
running debian stretch we upgraded BIOS from P3.00 to P4.60 and this
changed the integrated motherboard ethernet device name from enp10s0 to
enp37s0. As a consequence we lost network connectivty and had to edit
configuration files.

Initial BIOS:
r8169 0000:0a:00.0 enp10s0: renamed from eth0

New BIOS:
r8169 0000:25:00.0 enp37s0: renamed from eth0

On older versions debian /etc/udev/rules.d/70-persistent-net.rules
would have made the ethernet device name constant and we would
not have lost network connectivity, so the current state of udev is an
unfortunate regression.

Is there a way to force generation of 70-persistent-net.rules?

Thanks in advance,

Sincerely,

Laurent
