That's for IPv4 only? It was a while ago, when I looked at it, but as I remember you can achieve that by filling first 64 bits of RSS hash with some meaningful values, and keeping remaining RSS bits as zeroes. You probably can give it a quick try with testpmd. There is a nice article about similar subject: http://www.ndsl.kaist.edu/~kyoungsoo/papers/TR-symRSS.pdf Konstantin
