Subject: [PATCH net 2/3] net: hns3: initialize the message content in hclge_get_link_mode()
Date: Thu, 29 Apr 2021 16:34:51 +0800	[thread overview]
Message-ID: <1619685292-46644-3-git-send-email-tanhuazhong@huawei.com> (raw)
In-Reply-To: <1619685292-46644-1-git-send-email-tanhuazhong@huawei.com>

From: Yufeng Mo <moyufeng@huawei.com>

The message sent to VF should be initialized, otherwise random
value of some contents may cause improper processing by the target.
So add a initialization to message in hclge_get_link_mode().

Fixes: 9194d18b0577 ("net: hns3: fix the problem that the supported port is empty")
