Subject[PATCH net-next 06/12] net: hns3: Set STATE_DOWN bit of hdev state when stopping net
Date
From: Fuyun Liang <liangfuyun1@huawei.com>

We clear STATE_DOWN bit of hdev state when starting net, but do not set
it again when stopping net. It causes that the net is down, but hdev state
is still up. STATE_DOWN bit of hdev state should be set when stopping net.

Fixes: 46a3df9f9718 ("net: hns3: Add HNS3 Acceleration Engine & Compatibility Layer Support")
Fixes: e2cb1dec9779 ("net: hns3: Add HNS3 VF HCL(Hardware Compatibility Layer) Support")
