From: Sven Eckelmann <sven.eckelmann@openmesh.com>
Date: Thu, 21 Dec 2017 10:17:40 +0100
Subject: [PATCH] batman-adv: Remove kernel fixed width types in packet.h

The uapi headers use the __u8/__u16/... version of the fixed width types
instead of u8/u16/... The use of the latter must be avoided before
packet.h is copied to include/uapi/linux/.
