[PATCHv3 net-next 0/6] 6lowpan: address uncompression fixes

[Alexander Aring <alex.aring-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>]

The current implementation to uncompress addresses in a 6lowpan header
is completely broken.

This patch series fixes the parsing of addresses in a 6lowpan header.
It contains a major rewrite of the uncompress address function to parse
the address in a correct way.

Tested with the ravenusbstick(contiki 6LoWPAN stack) and beaglebone
(linux 6LoWPAN Stack) on the other side. The linux side contains all
possible addresses for the uncompression cases. Then I type a ping6 for
each case and lookup in wireshark and dmesg the correct reconstruction.

Please apply this patch series on net-next in order 1/7 to 7/7.

Changes since v3:
 - Fix byte ordering problem in uncompression of short-address.
   Thanks for this hint.
 - drop pr_debug before lowpan_raw_dump_inline

Changes since v2:
 - Add tags for net-next
 - Change commit msg in Patch 1/6 that this patch depends for the following
   patches
