Subject: [PATCH net-next 04/11] net: hns3: add l4_type check for both ipv4 and ipv6
Date: Thu, 28 Jun 2018 12:12:22 +0800 [thread overview]
Message-ID: <1530159149-122284-5-git-send-email-lipeng321@huawei.com> (raw)
In-Reply-To: <1530159149-122284-1-git-send-email-lipeng321@huawei.com>
HW supports UDP, TCP and SCTP packets checksum for both ipv4 and
ipv6, but do not support other type packets checksum for ipv4 or
ipv6.
