[PATCH net-next 12/12] net: hns3: log and clear hardware error after reset complete

From: Huazhong Tan
Date: Wed Oct 16 2019 - 03:20:29 EST

From: Jian Shen <shenjian15@xxxxxxxxxx>

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.
