I'm hoping I'm experiencing the same bug and the fix could be updated to
work on Mantic, and committed.
ThinkPad P16s, Hybrid dock 40AF, inbuilt ether port works fine, dock
ether port works fine in normal mode. If I enable MAC pass-through in
BIOS, only a carrier signal is detected, connection fails at DHCP step,
and no Internet connection can be established.
WiFi is unaffected.

Lenovo dock MAC Address pass through doesn't work in Ubuntu
Status in linux package in Ubuntu:

Bug description:
=== SRU Justification ===
[Impact]
Lenovo dock doesn't support MAC passthrough.
[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!
