pbuf->len is the length of this pbuf.  pbuf->tot_len is the sum of the lengths 
of this pbuf and all those chained together to form a packet using pbuf->next. 

Having pbuf->len=0 is a bit odd though.  Is this for a received packet or one 
you are sending?  Is there another pbuf linked by pbuf->next?  If so, what is 
its length?
