Subject: [dpdk-stable] [PATCH 19.11.6 02/13] net/hns3: check TSO segment size during Tx
Date: Fri, 13 Nov 2020 21:36:59 +0800
Message-ID: <1605274630-23414-3-git-send-email-oulijun@huawei.com> (raw)
In-Reply-To: <1605274630-23414-1-git-send-email-oulijun@huawei.com>

From: Hongbo Zheng <zhenghongbo3@huawei.com>

[ 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")
