Not fixed; but predictable. See: https://www.freedesktop.org/wiki/Software/systemd/PredictableNetworkInterfaceNames/ It would appear you have moved from scheme 4 to scheme 3, ie from 4. Names incorporating the interfaces's MAC address (example: enx78e7d1ea46da) to 3. Names incorporating physical/geographical location of the connector of the hardware (example: enp2s0) Cheers, David.
