[PATCH net 4/6] net: hns3: disable mac in flr process

From: Guangbin Huang
Date: Mon Sep 13 2021 - 09:14:57 EST


From: Yufeng Mo <moyufeng@xxxxxxxxxx>

The firmware will not disable mac in flr process. Therefore, the driver
needs to proactively disable mac during flr, which is the same as the
function reset.

Fixes: 35d93a30040c ("net: hns3: adjust the process of PF reset")
