Public bug reported:

Updating from Linux 5.15.0-88-generic to 5.15.0-90-generic breaks
ethernet support.

In my setup, the ethernet port is inside a Thunderbolt Dell WD19TB
docking station.

On 5.15.0-88 the ethernet device works and is shown with ip and on dmesg
logs :

$ sudo dmesg

On 5.15.0-90 the device cannot be found.

Thanks for looking into this regression.
