This information is tracked by udev in /etc/udev/rules.d/ within some
file there.

The behavior of NetworkManager in the case you seem to describe (my
apologies if I'm wrong, I only had time to read this far) is correct
here. You need to purge the udev file so when the MAC changes the
device shows up as eth0 when it boots.
