Is there any method for distributing the random IP packet stream into several VF queues evenly? For example, for each 4 VF queues, can each a quarter of the IP stream be distributed to each 4 VF queues? I checked the PFUTA register and tested it, but as far as I know, with the 4K bit hash table, the stream is directed to queues of which ROPE bit is set. So, the stream is duplicated to the queues of which ROPE bit is set. That is not what I want to do. How can I distribute the random IP packets to several VF queues without duplicating? Thanks in advance. Best Regards, J.Hwan Kim
