====================
6lowpan: fix issues with byte ordering types

I got some mail from a "kbuild test robot" and it detected some byte
ordering issues with the tag and datagram size value of 6LoWPAN IEEE
802.15.4 fragmentation header.

This patch series should fix the issues with the byte ordering.
