Not really. Why would you need the ability to route packets through the VF back to the local VF? It seems like that would give you much worse performance than just routing through the loop-back interface. Are you trying to loop-back a multicast packet of some sort from one application to another internally? Also using the VFs in this way would be quite limiting as it maxes out at roughly 25Gb/s per adapter since that is the upper limit for the PCIe bandwidth. Using loop-back you wouldn't have such a limitation. - Alex ------------------------------------------------------------------------------ Dive into the World of Parallel Programming.
