I have it working with 23.05.5 by configuring a manual MAC on the eth0 interface that matches the sticker on the device. Then configuring the device bridge with both eth0 and eth1 physical interfaces with the same MAC as the eth0 interface. Only eth0 is plugged in but shows no activity on the port lights. All activity show on teh flashing lights on the eth1 interface that is not plugged in.
I am not sure how this is working like this but it is.
If there is a better way of 'swapping' the physical interfaces then let me know. As you know these devices can only be powered from eth0.
As of now 23.05.5 is working this way on this device with manual MAC addresses configured.
Cheers
