The README suggests we need to change the structure of the test overall.

Reading it closely, it seems to imply that we need to specifically test with LLDP enabled before disabling it, and that we do not disable LLDP at the interface level for the 2nd test.

I am happy with that in a follow-up patch though, let's leave the re-opened bug open in that case though.
