We believe on our HW, HFI VNIC design gives better hardware resource usage 
which is also scalable and hence room for better performance.
Also as evident in the cover letter, it gives us better manageability by 
defining virtual Ethernet switches overlaid on the fabric and
use standard Ethernet support provided by Linux.
