and albeit for a SFP g.fast module it indicates/implies that Metanoia
provides own Linux drivers (supposedly GPL licensed), plus some bits
pertaining to the EBM (Ethernet Boot Management protocol).

Has Metanoia submitted any SFP drivers to upstream kernel development?

I have also not seen any. You could ask for the sources. It is
unlikely we would use them, but they could provide documentation about
the quirks needed to make this device work properly.
