after reading the thread I think it does not cover the topic exactly.
The creator of that thread liked to change the MAC address form
the hardware/firmware given to a different one. Which was fixed during
the thread.

In this case, the hardware/firmware given MAC changes without user
interaction but with a (each?) new kernel.

As diffusae <punasipuli at t-online.de> wrote during the named thread:

The shown serial number of the board does not change. An so the MAC
for ue0 should not. Especially it should start with the fixed range.
