   Interesting that you have anything in that directory at all; the one   
   on my Debian Unstable system is empty.   
      
   This symlinking to /dev/null is called “masking”. It explicitly   
   disables those service entries (originals present in   
   /lib/systemd/network in this case) so they cannot be   
   (easily/accidentally) enabled.
