There is no action like this since hardware does not support it. Multi queue support comes from the original queue support which was done as collaboration between Intel and Microsoft (for Windows). Then Linux got multi-queue (RSS) support. Then DPDK got similar multi-queue. Packet spraying across queues would be bad since it would create out of order packets, and also lots of lock contention on any shared per flow resource.
