Lenovo USB3 Dock Ethernet Not Working After Upgrading to 7.6

Before 7.6 software, the Ethernet link would incorrectly auto negotoate unsupported half duplex speeds (eg if it was connected to a hub rather than a switch). The link lights would be on, but it would not have worked properly.

Now the link is correctly not connected in this state. You will be seeing the link coming up, trying to negotiate and not finding a matching speed, and disconnecting.

To solve this, connect the Ethernet of the dock to an Ethernet switch rather than a hub.
