PS5, Line 75: This software *may* work with IFDv2 systems, if the GbE NVM data structure
I've successfully tested this on a Meteor Lake platform (Clevo V540TU), seems to work well without issues. One thing of note, is that a clean, unpopulated GbE blob there only has part 0 populated, part 1 is all 0xFFs, so I needed to run `nvm copy 0` before setting the MAC. Not sure if that's also the case for other platforms.
