Subject: [dpdk-stable] [PATCH 19.11.6 06/13] net/hns3: cleanup duplicated code on processing TSO in Tx
Date: Fri, 13 Nov 2020 21:37:03 +0800 [thread overview]
Message-ID: <1605274630-23414-7-git-send-email-oulijun@huawei.com> (raw)
In-Reply-To: <1605274630-23414-1-git-send-email-oulijun@huawei.com>
From: Chengchang Tang <tangchengchang@huawei.com>
[ upstream commit a001f09d11fac91b760c038cf69af7b041bc983c ]
This patch fixes up paylen calculation twice when processing TSO request
in the '.tx_pkt_burst' ops implementation function to avoid performance
loss.
Fixes: 6dca716c9e1d ("net/hns3: support TSO")
