Wolfgang, I of course am not going to argue with you - I don't have the big picture you have. So, let me take back my statement about this being useless in general :-)
But I certainly see a class of applications where it brings no value, as I described above. While I am fixing some other issues with the 570x driver, I will suggest a patch to make this switching optional.
Cheers, vadim

interface B. This automated interface skipping is actually a very harmful in some situations.
Perhaps you might be so kind as to elucidate?
The ability to register multiple interfaces and pick one of them for all communications is a great one. But the automated switch from interface to interface should definitely not be the default behavior.
THis is your opinion. Me, and others, disagree.
I wonder what is the u-boot community consensus on this issue. I guess not many people bring up boards with multiple enet interfaces...
You may be wrong. There may be more customers using this feature than you expect, and the number of systems where it's being used in production is probably in the millions by now.
Best regards,
