I tested the above kernel on a ThinkPad X1 Carbon 7th with a Thunderbolt
Dock 2nd Gen.
Below it the result when inserting cable into local Ethernet:

Below it the result when inserting cable into Dock Ethernet and enabled Mac
Pass Through in BIOS:
u@u-ThinkPad-X1-Carbon-7th:~$ ip a

so, in the 3rd testing, the IP still get from Dock's address e0:4f:43:95:97:fa,
it seems the Mac Pass through did not work.

Title:
Lenovo dock MAC Address pass through doesn't work in Ubuntu
Status in linux package in Ubuntu:
Confirmed
Bug description:
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!
