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.
