Yes, you are right, following is from i40e datasheet:

The EEPROM Manager tool writes a unique 32-bit eTrack_ID number in two
sequential NVM words.
The eTrack_ID is written when EEPROM Manager tool creates an image on
the Intel network. The eTrack_ID DB tracks NVM images back to a specific
SCM build

So it is unique, and can be used to identify FW version. And yes it can
be enough on its own without having major minor FW version fields.

Right, I read it wrong, i40e also has 32bits etrack-id.
