Olivier Matz 6d714a237d mbuf: fix performance of freeing with non atomic refcnt ... When RTE_MBUF_REFCNT_ATOMIC=n, the decrement of the mbuf reference counter uses an atomic operation. This is not necessary and impacts the performance (seen with TRex traffic generator). We cannot replace rte_atomic16_add_return() by rte_mbuf_refcnt_update() because it would add an additional check. Solves this by introducing __rte_mbuf_refcnt_update(), which updates the reference counter without doing anything else.
