Subject: [PATCH net-next v2 2/2] hinic: add support for rss parameters with ethtool
Date:   Tue, 11 Jun 2019 18:12:34 +0000
Message-ID: <20190611181234.4843-3-xuechaojing@huawei.com>

Precedence: bulk

This patch adds support rss parameters with ethtool,
user can change hash key, hash indirection table, hash
function by ethtool -X, and show rss parameters by ethtool -x.
