And still, this is somehow broken for turned off autoneg. Not a DoS
anymore, but it seems like one can not disable duplex autoneg. No matter
what duplex settings I configure on each side, communication is still
possible.

Do you have any idea what could be missing or how to furtherly track
down the problem? Could this even be a bug in the hardware?

Best wishes, Phil
