The aim of this patchset is firstly to refactor code in nr_route.c in order to make it
easier to read and maintain and, secondly, to mark some expected switch fall-throughs
in preparation to enabling -Wimplicit-fallthrough.

I have to mention that I did not implement any unit test.
If someone has any suggestions on how I could test this piece of code
it'd be greatly appreciated.

Series applied, thank you.
