[dpdk-dev] [PATCH 10/11] net/hns3: fix link status when failure in issuing command

[Wei Hu (Xavier)]

From: "Wei Hu (Xavier)" <xavier.huwei at huawei.com>

Currently, the hns3 PMD driver issues command to the firmware and gets link
status information.

When the driver fails to call internal interface function named
hns3_cmd_send to query the status from firmware for some reason, the link
status queried by the driver should be down.

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