Well, IIRC, this is not about the hardware. `NM` is only used by Intel's tools
and at some point they changed the meaning a little, it seems at least. I think
the best way to figure it out is to use a matching version of Intel's FIT tool,
generate one descriptor with GbE and one without. Compare `NM` to the expected
value (I guess at least 3 masters with GbE; if it actually changes with GbE
disabled, idk.).
