Seems like old eth interface names cannot read name_assign_type:
cat /sys/class/net/eth0/name_assign_type
cat: /sys/class/net/eth0/name_assign_type: Invalid argument

systemd x.link needs name_assign_type

Have you done a git bisect to figure out which change broke it?

The 5.10 kernel on my Debian desktop has this issue. So it is older
than that.

No, I have not used systemd before, also on 5.10.latest, I am setting up a new FW @home and decided to try out systemd.

Debian systemd does not seem to mind not being able to read
/sys/class/net/eth0/name_assign_type. At least my Ethernet interface
is working O.K.
