Sorry, but I don't understand your response. Both IPoIB and SRP were standardized
and implemented years before hfi was brought into the RDMA stack, so on
time of introduction they clearly supported all the devices.

Does this VNIC interface have standard? Where can I see HFI wire
protocol to implement HFI VNIC support in our HW?

Thanks.
