As has been noted here, MAC addresses are not necessarily unique to an

On the other hand, they *tend* to be unique for a wide range of systems.
This makes them pretty comparable to LABELs on disks, and we have
a /dev/disk/by-label

Remember that udev already supports symlink stacking, and priorities and
such.

I don't think there's any danger of supporting a /dev/netdev/by-mac by
default, it'll be a benefit to most and those who don't have unique MACs
will just ignore it.
