Hi,
I don't think you can inject packets into the device queues.
However, you can achieve the same, sending mbufs between the worker
threads, using the provided ring functionality of DPDK -
http://doc.dpdk.org/guides/prog_guide/ring_lib.html.
The worker threads will need to try to dequeue regularly for the shared
ring(s).
Regards.
