IPReassembler error

[David Scott Page]

Hi,

It appears that IPReassembler does not restore the packet annotation.
This click fragment (rt[0] is the output of StaticIPLookup for the local
host):

rt[0]   -> IPPrint(rt.0,CONTENTS hex,NBYTES 80)
        -> IPReassembler
        -> IPPrint(ipr.0,CONTENTS hex,NBYTES 80)
        -> ipc :: IPClassifier( icmp type echo, - ) ;

generates this output:

160 byte ping payload output (no segmentation):
