Hi Benoit, sorry to hear that the SR-IOV still not working on your HW.
Have you tested the last patch from Intel?
Regarding Bhyve, you can use Vale switches (based on netmap).
On my machines, i get around ~33Gbps between VM (same local machine),
sometimes going towards 40Gbps... ( These are basic tests with iperf3
and TSO/LRO enabled).
@Michael Dexter is working on a document that contains configuration
examples and test results for the different network backend available in
bhyve.
If you need help, let me know and we can set up a call.
Take care.
Santi
