[dpdk-dev] [PATCH 6/6] net/hns3: fix link speed when VF device is down

["Min Hu (Connor)" <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")
