Subject: [PATCH net-next 08/12] net: hns3: remove dcb_ops->map_update in hclge_dcb
Date: Sun, 27 Jan 2019 00:49:17 +0800	[thread overview]
Message-ID: <20190126164921.3872-9-tanhuazhong@huawei.com> (raw)
In-Reply-To: <20190126164921.3872-1-tanhuazhong@huawei.com>

From: Yunsheng Lin <linyunsheng@huawei.com>

After doing down/uninit/init/up in hclge_dcb, it is not necessary
to call dcb_ops->map_update in enet, so hclge_map_update can be
called directly in hclge_dcb.

This is for preparing to call hns3_nic_set_real_num_queue with
netdev down when user changes mqprio configuration.
