[dpdk-dev] [PATCH 2/3] mbuf: change free_cb interface to adapt to GSO case

From: Yi Yang In GSO case, segmented mbufs are attached to original mbuf which can't be freed when it is external. The issue is free_cb doesn't know original mbuf and doesn't free it when refcnt of shinfo is 0. Original mbuf can be freed by rte_pktmbuf_free segmented mbufs or by rte_pktmbuf_free
