From fc7efcf44344029db0fa3b4628297c620d25641c Mon Sep 17 00:00:00 2001 From: Huazhong Tan Date: Mon, 31 Dec 2018 10:58:29 +0800 Subject: [PATCH] net: hns3: call hns3_nic_net_open() while doing HNAE3_UP_CLIENT For HNAE3_DOWN_CLIENT calling hns3_nic_net_stop(), HNAE3_UP_CLIENT should call hns3_nic_net_open(), since if the number of queue or the map of TC has is changed before HHAE3_UP_CLIENT is called, it will cause problem. Also the HNS3_NIC_STATE_RESETTING flag needs to be cleared before hns3_nic_net_open() called, and set it back while hns3_nic_net_open() failed.
