DPDK is not designed for random additional threads.
You could use rte_ctrl_thread_create or do the working of creating, binding threads to cores,
and registering; but the startup does that already.
DPDK is designed for run to completion model where there is one thread bound to a core (and isolated).
You can try other things, but that makes things worse not better.
performance will be worse, can deadlock, will require additional locking etc.
