Subject: net: hns3: disable mac in flr process
From: Yufeng Mo <moyufeng@xxxxxxxxxx>
commit b81d8948746520f989e86d66292ff72b5056114a upstream.
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")
