[ upstream commit b68259f775b749ae860dfa4e170dd01774bf30d7 ]
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.
Fixes: 6dca716c9e1d ("net/hns3: support TSO")
