Please not yet, this is broken ! udp decoding and some upper layers can not
handle incomplete packets. I have fixed the udp decoding but not all other
ones the previous week-end when I tried to do the same thing and I got a
endless loop or segmentation violation in upper layer decoders... and I hate
to see the ICMP info field replaced by UDP or NBNS for instance :-)
