Subject: [PATCH net-next 8/8] net: hns3: log and clear hardware error after reset complete
Date: Sat, 19 Oct 2019 16:03:56 +0800 [thread overview]
Message-ID: <1571472236-17401-9-git-send-email-tanhuazhong@huawei.com> (raw)
In-Reply-To: <1571472236-17401-1-git-send-email-tanhuazhong@huawei.com>
From: Jian Shen <shenjian15@huawei.com>
When device is resetting, the CMDQ service may be stopped until
reset completed. If a new RAS error occurs at this moment, it
will no be able to clear the RAS source. This patch fixes it
by clear the RAS source after reset complete.
