From 841a5ec72c028432f716670c4a7c2e1b70ee1341 Mon Sep 17 00:00:00 2001 From: Alexander Aring Date: Thu, 12 Dec 2013 20:15:25 +0100 Subject: [PATCH] 6lowpan: fix/move/cleanup debug functions There are several issues on current debug behaviour. This patch fix the following issues: - Fix debug printout only if DEBUG is defined. - Move debug functions of 6LoWPAN code into 6lowpan header. - Cleanup codestyle of debug functions.
