Hello!

 

I have tried to use RSS, I do the same piece of code on NXP ls2160 and on Intel with the 82599ES, on NXP I see that incoming traffic is distributed across queues.

On Intel I see that all incoming packet still in the queue #0.

So, what I'm need to check additionally (at initialization/setup time)   ?

 

Thanks-in-advance.
