Stefan Roese already recommended to enable the debug output in the 4xx ethernet driver - did you do this? What did it say?

Yes, Philippe had enabled debug output (#define INFO_4XX_ENET).

I've re-enable them with top-of-git u-boot version, trace looks like previous one.

Best regards

Here is the trace:
