Yes, TEP 125 promises the implementation of an I-Frame to show up soon
in tinyos-2.x/tos/chips/cc2420. I was hoping that this would allow me to
use the whole 802.15.4 payload once it shows up without having to change
things in tinyos-2.x/tos/chips/cc2420 or at least minimize the necessary
changes. Hence, I have not tried to implement something myself.

If an I-Frame implementation would make it easier to get rid of the AM
Type field I'm happy to use it. I also have not optimized my buffers and
structures heavily, but it may be then possible to directly embed
something like a message_t in lowpan_pkt_t and use it instead of a
uint8_t[102]. lowpan_pkt_t is a struct I am using to represent a packet.
