Subject: net: hns3: disable mac in flr process
Patch-mainline: v5.15-rc2
Git-commit: b81d8948746520f989e86d66292ff72b5056114a
References: bsc#1190336 stable-5.14.7

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")
