The following commit has been merged in the master branch: commit 4e58452b6fc391c35611693b12a3f97bd60f6da8 Author: Sven Eckelmann <sven.eckelmann(a)openmesh.com> Date: Thu Dec 21 10:17:38 2017 +0100 batman-adv: Let packet.h include its headers directly The headers used by packet.h should also be included by it directly. main.h is currently dealing with it in batman-adv, but this will no longer work when this header is moved to include/uapi/linux/.
