Compare implementations of rename_netif in

(traditional udev, which handles collisions) and
https://github.com/systemd/systemd/blob/main/src/udev/udev-event.c 
(systemd-udevd, which does not handle collisions).  

That explains some user reports I've been seeing :o

Then submit a change to add the logic back.  This looks like a userspace
tool breaking existing setups, so please take it up with the developers
of that tool.  The kernel has not changed or "broken" anything here.  

(I didn't mean to imply that the kernel was to blame, merely that a 
kernel change could help make things tidier.)

If you're attempting to fix this in systemd please share the PR info
so we can voice support!
