Lenovo docking station not working

Hi, I just bought a Lenovo Hybrid USB-C/USB-A docking station for my X1 Carbon thats running FreeBSD. I can't get it to play nicely. It seems to detect the dock, lights flash etc. Can turn the laptop on/off via the button on the dock. I bought it to connect 2 external monitors and ethernet (since the laptop is missing an ethernet port).

My questions:
  • How can I make it work so that I can connect my HDMI/DisplayPort screen ?
  • How do I setup the LAN connection via the dock?

usbconfig when connected to USB-C:

xrandr doesn't detect any extra screens.

Can anyone help me out / point me in the right direction?
 
I don't dock my Thinkpads anymore. The first T61 I purchased off ebay looked like it just came out of the box. I was compiling ports and it would be busy a while so I unplugged the USB mouse from the dock.

That was the end of it. It froze and after giving it plenty of time to pick back up had to do a hard reboot IIRC. It went to laptop heaven and if I didn't shed a tear at its demise it wasn't because I didn't feel like it. It's still good for parts if I need it.
 
I just got the opportunity to test a USB-C docking (Gen2) with my X1 Carbon Gen6. I didn't pushed it too far, however the display port worked without issue. It didn't on the Gen 1 docking. Charge didn't worked, and ethernet was blinking but didn't worked either. If I have more time I'll dump the output of my dmesg here. I'm running 12.0 p12.

Were you able to get the ethernet connection working? I've got freebsd running on a thinkpad p72, and the output would be helpful.

For now, I didn't had luck with any of the docking I tried, that is Gen1 & 2 Docking from Lenovo, QDos Powerlink Grand, i-tec USB-C Metal 4K, so I kept using the dongle, which is good enough for me. Will see with updated kernel.
 
I was quite surpised to see Gen2 working in OpenBSD. Ethernet was recognized as cdce0 and worked properly. Some weird things happened to the displays and X though, I didn't figure out the problem yet.
Today tried to make it work on FreeBSD, unfortunately no success with the Ethernet so far. Displays are working great.
