Subject: [PATCH 3/4] net-next/hinic:fix a bug in set mac address
Date: Mon, 19 Nov 2018 06:12:33 +0000 [thread overview]
Message-ID: <20181119061234.12839-3-xuechaojing@huawei.com> (raw)
In-Reply-To: <20181119061234.12839-1-xuechaojing@huawei.com>
In add_mac_addr(), if the MAC address is a muliticast address,
it will not be set, which causes the network card fail to receive
the multicast packet. This patch fixes this bug.
