When starting on both FreeBSD and Linux the latest driver complains that the NVM should be updated.
As there's no FreeBSD NVM update utility available I got the machine temporarily booted into Linux however the updater reports:
"Update not available"
The log from an inventory run identifies the card as a dual port X710:
[02:00:00]: Intel(R) Ethernet Converged Network Adapter X710

Looking in nvmupdate.cfg the device matches the XL710 but there's no match for EEPID which I believe corresponds to the EEPROM: EtrackID of 80001867.
So the question is where do I get the right NVM update from?
./nvmupdate64e -l update.log
