Subject: [dpdk-dev] [PATCH 3/8] net/hns3: fix Tx checksum with fix header length
Date: Mon, 2 Nov 2020 22:38:14 +0800 [thread overview]
Message-ID: <1604327899-60126-4-git-send-email-oulijun@huawei.com> (raw)
In-Reply-To: <1604327899-60126-1-git-send-email-oulijun@huawei.com>
From: Chengchang Tang <tangchengchang@huawei.com>
Currently, the header length of all the layers are fixed, It would
lead to a csum error when the header length changed.
This patch fixes above problem by using the header length in mbuf
instead of the fixed header length to perform the TX cksum offload.
Fixes: bba636698316 ("net/hns3: support Rx/Tx and related operations")
