On Mellanox cards, this is already possible via phys_switch_id, as
each PF has its own phys_switch_id. So all VFs with a given
phys_switch_id belong to the PF with that same phys_switch_id.

I understand this is a vendor-specific design, but if you have the
same phys_switch_id across PFs, does it really matter on which PF the
VF was created on?
