Hi Oleg, ixgbe defaults to having ATR on so Tx traffic's flow will set on the queue assigned to the CPU it was sent out on. This way incoming packet to that flow will arrive on the same queue.
It sounds like you want greater control of which queue a flow is assigned. Take a look at perfect filter and see if that will give you what you're looking for.
