Subject[PATCH net-next 08/10] net: hns3: Fix for fiber link up problem
Date
From: Yunsheng Lin <linyunsheng@huawei.com>

When hclge_ae_start is called, hdev->hw.mac.link may be set
to one after up/down multi-times, which does not correspond to
the link state of netdev when the netdev is up.

This fixes it by setting hdev->hw.mac.link to zero when
hclge_ae_start is called.

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