I test it and can confirm that it does do "more" reaction on probing.
I get now:

Don't know why I get it, I use the current mainline dts files for the RPi.
Maybe somebody can help me here?

Nevetheless I think it's hurts to use an Ethernet PHY which is connected
via USB. Additional I have no good experience with RPi and USB. :-/
