MS-Word is *not* a good format to post a picture. You're lucky I have a 
viewer for that around. If you send an image, please send only the image 
next time!

Aside from that, I still cannot really tell what's wrong. Since I don't 
have access to your hardware, you should try to debug it yourself a 
little. Here are some starters:

- Why does the assert fail? (i.e. compare increment_magnitude against 
p->len)
- is the contents of the packet correct? (compare against packet shown 
by an ethernet sniffer like wireshark)
- if that doesn't help, try going up one step in the callstack and see 
what's happening in ip_reass with the pbufs and why p->len is too short 
(if it is)

One reason could be that your pbufs are too short and the the IP header 
does not fit into the first pbuf in the queue, but I cannot tell that 
from here.
