Thanks for following up on these patches. It would still be nice to have performance numbers to show the impact. These will be helpful for the next task of integrating RFS into virtio-net.I don't get why RFS need to be integrated into virtio-net since virtio-net has supported mq. Can you give some clue? thanks.
In this case RFS would be the mechanism for selecting the RX queue. We can either use the tun approach which is to match the RX queue to the TX queue for a flow, or expose it as accelerated RFS to the guest. Fine grained control of the queue selection should have value.

Since Tom Herbert's hash related patchset was modified and got merged, his pachset about adding support for RFS on tun flows also need to get adjusted accordingly. I tried to update them, and before i will start to do some perf tests, i hope to get one correct code base, so it's time to post them out now. Any constructive comments are welcome, thanks.Series applied to net-next, thanks.-- Regards, Zhi Yong Wu
