Subject: [Patch net-next 09/12] net: hns3: Record VF unicast and multicast tables
Date: Wed, 20 Feb 2019 10:32:48 +0800 [thread overview]
Message-ID: <1550629971-23999-10-git-send-email-tanhuazhong@huawei.com> (raw)
In-Reply-To: <1550629971-23999-1-git-send-email-tanhuazhong@huawei.com>
From: liuzhongzhu <liuzhongzhu@huawei.com>
Record the unicast and multicast tables that the VF sends to the chip.
After the VF exception, the PF actively clears the VF to chip config.
