Ideally what we receive is the same as on the wire, but I think your
solution would be fine.

In addition to the reassembled packet, having an option to receive the
individual frags as well would be of use. Suricata (and Snort as well)
has it's own defrag code that does anomaly detection. I can see a use
case where just for that anomaly detection we'd still want to see the
frags. In that case it wouldn't be a problem that they would all go to
fanout 0.
