Hi there,

I'm wondering if I want to queue the same rte_mbuf to multiple rte_rings do
I need to copy the packet (rte_pktmbuf_copy) or just bumping up the
reference count (rte_pktmbuf_refcnt_update) before the queueing is enough?
The rings are consumed by separate processes. Will the ref count
work correctly across the processes and only the last process free the
given rte_mbuf?

Thanks,
Pavel.
