I think the main valid argument for a revert is that it violates the
documented dtb ordering rule. It also fails to actually do what it was
intended to do since network device probing order really isn't defined
in linux and if you care you should fix it in userspace. Fixing a
regression would be a side effect, and since the ordering isn't certain
anyhow, anyone that did see a regression was doing it "wrong" already,
although also anyone that saw a benefit from the change was also doing it

Yeah they better come up with a safer way to determine which network
device is which from user space.
