The quirk is for system BIOS's that don't fully support SR-IOV.  The quirk is for those systems with these bad BIOS's with our (and others) devices in them.  So we think the same quirk could be used but we have never test with it in a system with a Niantic device in it.  So we don't know if it would work or not.  It should but without testing there is no way to know for sure.

Cheers,
John
