Yi Yang c0d002aed9 gso: fix mbuf freeing responsibility ... rte_gso_segment decreased refcnt of pkt by one, but it is wrong if pkt is external mbuf, pkt won't be freed because of incorrect refcnt, the result is application can't allocate mbuf from mempool because mbufs in mempool are run out of. One correct way is application should call rte_pktmbuf_free after calling rte_gso_segment to free pkt explicitly. rte_gso_segment must not handle it, this should be responsibility of application. This commit changed rte_gso_segment in functional behavior and return value, so the application must take appropriate actions according to return values, "ret < 0" means it should free and drop 'pkt', "ret == 0" means 'pkt' isn't GSOed but 'pkt' can be transmitted as a normal packet, "ret > 0" means 'pkt' has been GSOed into two or multiple segments, it should use "pkts_out" to transmit these segments. The application must free 'pkt' after call rte_gso_segment when return value isn't equal to 0.
