Subject: [dpdk-dev] [PATCH 6/6] net/hns3: fix link speed when VF device is down
Date: Sat, 15 May 2021 08:52:38 +0800	[thread overview]
Message-ID: <1621039958-34847-7-git-send-email-humin29@huawei.com> (raw)
In-Reply-To: <1621039958-34847-1-git-send-email-humin29@huawei.com>

From: Huisong Li <lihuisong@huawei.com>

When the port is link down state, it is meaningless to display the
port link speed. It should be an undefined state.

Fixes: 59fad0f32135 ("net/hns3: support link update operation")
