Subject[PATCH net-next 04/11] net: hns3: restore the MAC autoneg state after reset
Date
From: Jian Shen <shenjian15@huawei.com>

When doing global reset, the MAC autoneg state of fibre
port is set to default, which may cause user configuration
lost. This patch fixes it by restore the MAC autoneg state
after reset.
