Yes, something like:

test_one_pktmbuf(struct rte_mbuf *m)
{
	/* same as before without the allocation/free */
}

test_pkt_mbuf(void)
{
	m = rte_pktmbuf_alloc(pool);
	test_one_pktmbuf(m);
	rte_pktmbuf_free(m);

	ret = rte_pktmbuf_alloc_bulk(pool, mtab, BULK_CNT)
	for (i = 0; i < BULK_CNT; i++) {
		m = mtab[i];
		test_one_pktmbuf(m);
		rte_pktmbuf_free(m);
	}
}

Yes, please.


Thanks,
