I don't run FC31 but on all my other Fedora systems, I add net.ifnames=0

Then regenerate the grub menu:
# legacy BIOS
grub2-mkconfig -o /boot/grub2/grub.cfg
I don' have but one EFI server:
# EFI BIOS
grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg

That does not happen if I plug and unplug external, an ethernet cable.
BUT, what's really odd. I'm booting the Fc31 kernel:
kernel-5.3.11-300.fc31.x86_64
if I boot the same kernel, but FC30:
kernel-5.3.11-200.fc30.x86_64
IT WORKS !!
Any help appreciated.
I've seen the same issue some time ago (but on Centos 7).
The basic problem is that interface renaming must happen correctly
in the initramfs, where you have to be sure the network configuration
is fine;
that explains why a successive unplug/replug works.
In my case there was no NetworkManager involved, just the old
"service network start"
things, with configs in /etc/sysconfig/network-scripts/ifcfg*
No idea what can have happened between those two kernels, apart
from indeed having different intiramfs content.
You should try extracting the two initramfs and doing a comparison.
Something like:
[root@router boot]# cat z_decompress.sh
#!/bin/bash
set -e
initramfs=$1
/usr/lib/dracut/skipcpio $initramfs >z_decomp_$initramfs.cpio.gz
rm -Rf z_dir_$initramfs
mkdir z_dir_$initramfs
cd z_dir_$initramfs
gunzip <../z_decomp_$initramfs.cpio.gz | cpio -i
Best regards.
Thanks, but that's beyond my kernel skill set.
Here's what I tried, all without success:
1. put 2 .link files is /etc/systemd/network
ls /etc/systemd/network
10-external.link 10-internal.link
cat /etc/systemd/network/*
[Match]
MACAddress=50:7b:9d:0b:8a:ab
[Link]
Name=external
[Match]
MACAddress=00:0e:c6:dc:01:aa
[Link]
Name=internal
2. put 70-persistent-net.rule in /etc/udev/rules.d
cat /etc/udev/rules.d/70-persistent-net.rules
SUBSYSTEM=="net", ACTION=="add", ATTR{address}=="50:7b:9d:0b:8a:ab",
NAME="external"
SUBSYSTEM=="net", ACTION=="add", ATTR{address}=="00:0e:c6:dc:01:aa",
NAME="internal"
rebooted
One odd result of running udevadm test on the "external" interface:
enp1s0: Failed to rename network interface 2 from 'enp1s0' to
'external': Device or resource busy
There must be some trick here that I'm missing. What's the problem
with the FC31 kernel ?

I tried net.ifnames=0. That resulted in interface names eth0 and eth1.
And did not honor the persistent name request.
udevadm finds the 10-external.link file :
