Using any software (and udev in particular) in a wrong way will give you
wrong results. As a programmer, you should be familiar with it :)

Try this link file:

[Match]
Driver=e1000e
[Link]
MACAddressPolicy=none
NamePolicy=kernel


Long story short, NIC double renaming is wrong, and matching a NIC by
its MAC alone is wrong too.

The software merely does what it's told to do.
