This is degenerating in an off-topic discussion. The question is how to rename the network device back to eth0. Let's focus.
At this point, "use the source, Luke" appears to be the only option :-(
I see on my system in dmesg output this string:
[ 4.173161] systemd-udevd[420]: renamed network interface eth0 to em1
If I run "strings" on /usr/lib/systemd/systemd-udevd, I find this:
renamed network interface %s to %s
So, if you really want to be fanatical, you could download the source rpm for systemd, "rpmbuild -bp" it to expand the source tree, then search the source for the string "renamed network interface" and work backward from there to see if there is a path the code can be induced to go through that won't do the rename :-).
Or maybe it would be simpler to use a binary editor on the "Matlab" code and change all "eth0" strings to "em1" :-).
