Hi,

What's the use case for save_fragmented? The documentation doesn't explain why it's there:
https://www.wireshark.org/docs/wsdg_html_chunked/ChDissectReassemble.html

The context leads me to think that save_fragmented is only relevant in this case because the example deals with a custom fragmentation protocol over UDP...
Maybe for IP-in-IP it would be significant too but could someone please 
clarify for me the intended usage?
Does something else happen using pinfo->fragmented after the IPv4/IPv6 
dissector returns?
Thanks,

João V.
