Subject: [PATCH 07/10] net: hisilicon: Add group field to adapt HI13X1_GMAC
Date:   Fri, 5 Jul 2019 14:12:00 +0800
Message-ID: <1562307120-103799-1-git-send-email-xiaojiangfeng@huawei.com>
MIME-Version: 1.0
Content-Type: text/plain
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

In general, group is the same as the port, but some
boards specify a special group for better load
balancing of each processing unit.
