1 From: Sven Eckelmann <sven.eckelmann@openmesh.com>

3 Subject: [PATCH] batman-adv: Remove kernel fixed width types in packet.h
4
5 The uapi headers use the __u8/__u16/... version of the fixed width types
6 instead of u8/u16/... The use of the latter must be avoided before
7 packet.h is copied to include/uapi/linux/.
