I had 6LOWPAN support for IRIS, but only if you define the
IEEE154_6LOWPAN variable. I am suprized that the I-frames are the
default, do people really use them? The TEP does not say a thing about
TRFAMES_ENABLED!

Ok, so the expected behaviour should be:

Outgoing messages should set the NALP network code for tinyos: 63

Incoming messages should be checked, if the NALP code is incorrect
then you drop them, right? No snooping in this case.
