Okay. I added this and now the warning seems gone. Please check the below l=

Yes.

With fec0 fixed-link and 3 different switch port configurations, the
result of the link seems to be up but the ping not working and even
the packets are not transmitted via eth0.

DT Combinations:

- Port0 is ethphy0, Port1 is ethphy1, Port2 is disabled, Port3 is
disabled, Port4 is FEC
- Port0 is disabled, Port1 is ethphy0, Port2 is ethphy1, Port3 is
disabled, Port4 is FEC
- Port0 is disabled, Port1 is disabled, Port2 is ethphy0, Port3 is
ethphy1, Port4 as FEC


DT: (with Port0 is ethphy0, Port1 is ethphy1, Port2 is disabled, Port3
is disabled, Port4 is FEC)
