Maybe plain 'fw' should be used for this '9.30' as this is a version
of the whole software package provided by Intel for these adapters
(e.g. 
https://www.intel.com/content/www/us/en/download/18190/non-volatile-memory-nvm-update-utility-for-intel-ethernet-network-adapter-700-series.html).

Thoughts?

Combo image version (aka CIVD) is reported by nvmupdate tool and this
should be version of OROM that contains PXE, EFI images that each of
them can have specific version but this CIVD should be overall OROM 
version for this combination of PXE and EFI. I hope I'm right.

Thanks,
