As has been noted here, MAC addresses are not necessarily unique to an
interface.  As such, we are not proposing a net/by-mac/* symlink to
/dev/netdev/*.

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

[...]

MAC addresses are normally assigned automatically but can be overridden
if necessary.  In that respect they are more like UUIDs for disks.

I don't see any analogue of disk labels, though labels could conceivably
be added to some NICs using VPD.
