[PATCH net 4/6] net: hns3: disable mac in flr process
From: Guangbin Huang <hidden>
Date: 2021-09-13 13:14:57
Also in:
lkml
Subsystem:
hisilicon network subsystem 3 driver (hns3), hisilicon network subsystem driver, networking drivers, the rest · Maintainers:
Jian Shen, Jijie Shao, Andrew Lunn, "David S. Miller", Eric Dumazet, Jakub Kicinski, Paolo Abeni, Linus Torvalds
From: Yufeng Mo <redacted>
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")
