Without cross-numa-polling, VM/VHU queue traffic is evenly distributed based on

Please take a look and let us know your inputs.

Hi Kevin,
We have done extensive benchmarking and found that we get better overall
PMD load balance and resulting OVS performance when we do not statically
pin any rx queues and instead let the auto-load-balancing find the optimal

We do acknowledge the benefit of non-pinned polling of phy rx queues by
