I don't like that because we don't need batman-adv loaded to simply forward 
(bridge) traffic between interfaces. And not being able to use RPS with 
multiple cores just because the batman-adv module (and interfaces) is not 
enabled seems to be counter-intuitive.

Thanks for the feedback. I have it now implemented like in GRE.

The change can already be found in
