Consider updating your systemd version to a newer version (or ask your
distro to backport the relevant patches). The predictable network
interface naming received a number of tweaks since 245, and it's
pretty likely this has since been fixed. Specifically, the
NAMING_SLOT_FUNCTION_ID feature flag introduced with v249 will likely
fix your case.
