After booting into 5.3.0-26 on my Lenovo X390, it has started to loose network connection when connected to the Thunderbolt 3 Gen 2 dock after a while. No traffic goes through. Enabling wifi after it works fine, but unselecting "Enable Networking" in network manager makes the whole computer hang (can move mouse, but no input from keyboard is registered anymore, or so it seems at least)

[Fix] Add support to Lenovo Dock MAC passthrough. [Test] MAC passthrough works once the patch is applied. [Regression Potential] Low. Apart from adding support to Lenovo Dock, this patch only did minor refactoring to existing behavior, no functional change to current code. === Original Bug Report === Similar to bug https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1579984 the MAC address pass through does not work with a Lenovo Thunderbolt 3 Workstation Dock. The dock's network port is recognized and working but it has its own MAC address even though MAC Address pass through is enabled in the BIOS. This is the dock in question: https://www.lenovo.com/us/en/accessories-and-monitors/top-tech /Thunderbolt-WS-230W-dock-US/p/40AN0230US and the laptop is a Lenovo P1. Debug files attached. Please let me know if further info is required. Thanks!
