René Hummen requested more information:
Hi,

the HIP standard specifies that the I1 packet should be minimal (i.e., no 
additional parameters). The hipfw checks for this minimality in order to 
prevent an I1-based side channel for unauthorized payload data.

Miika, can you shed some light on this issue?
