Thanks. Then it might be something wrong in the phy side. I found a bug with the doubly entries, and that might be the cause of "RTL8208" error messages. I'm build yet again Leap 15.2 kernel in OBS home:tiwai:bsc1173085-3 repo with the correction. Even if this still shows the same error, it'll indicate the phy number in the error message, so it might help. Let's see.
