Oups, I missed, I created dummy device and modprobed again. Now I see:

$ sudo devlink port
mdio_bus/fixed-0:1f/0: type eth netdev lan1
mdio_bus/fixed-0:1f/1: type eth netdev lan2
mdio_bus/fixed-0:1f/2: type eth netdev lan3
mdio_bus/fixed-0:1f/3: type eth netdev lan4
mdio_bus/fixed-0:1f/4: type notset
mdio_bus/fixed-0:1f/5: type notset
mdio_bus/fixed-0:1f/6: type notset
mdio_bus/fixed-0:1f/7: type notset
mdio_bus/fixed-0:1f/8: type notset
mdio_bus/fixed-0:1f/9: type notset
mdio_bus/fixed-0:1f/10: type notset
mdio_bus/fixed-0:1f/11: type notset

I wonder why there are ports 4-11

Yeah, I'm a bit lost in the embedded/dsa world :)
