Subject: [PATCH net-next] hinic: fix a bug in set rx mode
Date:   Mon, 27 May 2019 22:10:05 +0000
Message-ID: <20190527221005.10073-1-xuechaojing@huawei.com>
MIME-Version: 1.0
Content-Type: text/plain
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

in set_rx_mode, __dev_mc_sync and netdev_for_each_mc_addr will
repeatedly set the multicast mac address. so we delete this loop.
