Public bug reported:
[Impact]
If a user manually disables autonegotiation, that setting will be lost if the
link is toggled.
[Test Case]
sudo ethtool -s enp125s0f2 speed 100 duplex half autoneg off
After this, "ethtool enp125s0f2" will show:
Advertised auto-negotiation: No
If you then run:
sudo ifconfig enp125s0f2 down; sudo ifconfig enp125s0f2 up, then ethtool will
show:
Advertised auto-negotiation: Yes
[Fix]
b01b7cf19bf4a net: hns3: Fix for information of phydev lost problem when down/up
[Regression Risk]
Restricted to a single SoC on which the fix was explicitly tested.
