commit c5e4e44b6ff332abd4db113918ce14c491bfdb57 Author: Sven Eckelmann sven@narfation.org Date: Thu Oct 25 18:22:10 2018 +0200

batctl: Move routing_algo command to separate file

More complex commands in batctl are stored in separate files which are called like the actual command name. This makes it easier to group functionality and detect which parts belong to a more complex construct.
