ugh nics with LAA?

yeah, it can be hard to 'uniquely' identify a nic, especially since it's
so common to clone macs for bonds, bridges, vlans, and in some cases
even duplicate hw devices with the same nic (e.g. bug 1843381).

MAAS installs do and configure netplan to always use the install-time
names.

I'm generally not a fan of how MAAS configures netplan to force-rename
interfaces; that sounds to me like it's destined for interface naming
collisions. But I don't have any better immediate suggestion for
'foolproof' matching of all possible nics that might exist across all
kernel driver versions, either.
