Bug Description

[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.

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-bionic' to 'verification-done-bionic'. If the problem still exists, change the tag 'verification-needed-bionic' to 'verification-failed-bionic'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!
