Merge branch '6lowpan'

Alexander Aring says:

====================
6lowpan: trivial changes

This patch series includes some trivial changes to prepare the 6lowpan stack
for upcomming patch-series which mainly fix fragmentation according to rfc4944
and udp handling(which is currently broken).

Changes since v3:
  - really fix intendation in patch 3/5

Changes since v2:
  - change intendation in patch 3/5
  - fix typo in 5/5 unecessary -> unnecessary
  - add missing 6lowpan tag in cover-letter
