+ * The caller must ensure that the mbuf is direct and properly
+ * reinitialized (refcnt=1, next=NULL, nb_segs=1), as done by
+ * rte_pktmbuf_prefree_seg().

+ * This function should be used with care, when optimization is
+ * required. For standard needs, prefer rte_pktmbuf_free() or
+ * rte_pktmbuf_free_seg().
