Subject: [dpdk-dev] [PATCH v2 2/2] examples/ethtool: add closing port operation
Date: Thu, 6 May 2021 11:46:08 +0800
Message-ID: <1620272768-42421-3-git-send-email-humin29@huawei.com> (raw)
In-Reply-To: <1620272768-42421-1-git-send-email-humin29@huawei.com>

From: Huisong Li <lihuisong@huawei.com>

Currently, ethtool directly ends the process after 'quit' cmd. In this
case, software resources are not released and hardware resources of the
device are not uninstalled.

This patch adds closing port operation to release resources.

Fixes: bda68ab9d1e7 ("examples/ethtool: add user-space ethtool sample application")
Cc: stable@dpdk.org
