- which layer? MAC, 6LoWPAN?
- bit or byte ordering?
If you code something and missed byteordering handling you can check it
with:
make C=2 net/ieee802154/ net/mac802154/
this requires the software "sparse".
_But_ this works only if you use correct the byteorder typedefs such as
"__le16", etc...

Which contiki version? I tested 2.6 with some self ported board only.
I know versions below had some fragmentation issues, which you not use.
