This patch is not following

 * https://www.open-mesh.org/projects/open-mesh/wiki/Contribute
 * https://www.kernel.org/doc/Documentation/SubmittingPatches
 * https://www.kernel.org/doc/Documentation/CodingStyle

Please add the "batman-adv: " prefix for the Subject.

The summary in the subject itself also needs to be refined. The relevant part 
in SubmittingPatches for the subject can be found under "14) The canonical 
patch format".

An explanation in the commit message why there is an overflow would be nice.

Kind regards,
	Sven
