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
