Lenovo usb-c mini dock ethernet port not working

[citral23]

Describe the bug

I have a lenovo usb-c mini dock (type 40AU) that works fine for the ports, charging and display out. however the cdc_ether driver fails to load so the network card is not seen by the OS

In dmesg we can see the driver trying to load, but failing quickly.

The ethernet interface is available in the bazzite Anaconda installer, and also in regular Fedora, on 2 different laptops.

What did you expect to happen?

I expect the driver to load and ethernet to be available.
