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
Alexander Aring (5):
6lowpan: remove unnecessary ret variable
6lowpan: remove unnecessary check on err >= 0
6lowpan: use netdev_alloc_skb instead dev_alloc_skb
6lowpan: remove skb->dev assignment
6lowpan: remove unnecessary break
