Subject: [PATCH net-next 4/9] net: hns3: add support for traffic class tuple support for flow director by ethtool
Date: Mon, 15 Mar 2021 20:23:46 +0800	[thread overview]
Message-ID: <1615811031-55209-5-git-send-email-tanhuazhong@huawei.com> (raw)
In-Reply-To: <1615811031-55209-1-git-send-email-tanhuazhong@huawei.com>

From: Jian Shen <shenjian15@huawei.com>

The hardware supports to parse and match the traffic class field
of IPv6 packet for flow director, uses the same tuple as ip tos.
So removes the limitation of configure 'tclass' by driver.
