From: Hongbo Zheng <zhenghong...@huawei.com>
Base on hns3 network engine, when the rte_eth_tx_burst API is called
by Upper Level Process, if PKT_TX_TCP_SEG flag is set and tso_segsz
is 0 in the input parameter structure rte_mbuf, hns3 PMD driver will
process this packet as an non-TSO packet, otherwise hardware will enter
an abnormal state.
