Public bug reported:
I'm using Lenovo Thinkpad t490 with ThinkPad Thunderbolt 3 Dock Gen 2.
When I boot Ubuntu with dock connected to thunderbolt port, there is a problem
with network connection. Usb network device is available and trying to connect.
Then I get connection failed message.
Dock is authorized

Unplugging and re-plugging LAN cable, does not help. Disabling network
from network manager does not help either.
When I unplug dock from the laptop and replug thunderbolt cable, network
connects without a problem.
