Thanks for this fast and precise answer!

I already tried this, and if I am not wrong in the procedure, this
produces the same error:
- dump EEPROM from working NIC on another laptop:
ethtool --eeprom-dump enp2s1 raw on > dump
- write dump file on faulty NIC:
ethtool --change-eeprom enp2s1 magic 0x100e8086 < dump

So I will have to try other ways :-(
