I am still not with you: are you referring to the case where each VM
is being served by a
different VF? in that case, the VF driver (mlx4_en) has no way to know
its a "loopback" packet,
and switching between VFs can be programmed to the PF by the PF driver
(modified mlx4_core).
If you are talking to the case both VMs are being served by the same
PCI function --> same NIC
then again, loopback is handled in higher level.
Is there a 3rd use case?
Or.
