Hi Damian

Using the conn_mgr library is not appropriate in this case since you need to choose a specific L2 layer, and conn_mgr will simply choose any L2 layer that is available.

The main problem in this case is that the eth_w5500.c driver doesn't support link detection yet, but luckily this was patched in Zephyr just weeks ago:
https://github.com/zephyrproject-rtos/zephyr/pull/68752

Once this is in place you can monitor the NET_EVENT_IF_UP and NET_EVENT_IF_DOWN events in order to check if the ethernet cable is connected or disconnected.

For an example of how to do this please have a look at this code.

Best regards
Torbjørn
