Subject: [PATCH net-next 08/10] net: hns3: Fix for fiber link up problem
Date: Tue, 15 May 2018 19:20:12 +0100	[thread overview]
Message-ID: <20180515182014.42196-9-salil.mehta@huawei.com> (raw)
In-Reply-To: <20180515182014.42196-1-salil.mehta@huawei.com>

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")
