You are right on the bits. All of them get affected. My only reference for what
is expected in the data base is the code for Base. In the base_payload.php file,
the ip_frag field get pulled out of the database and is used to create a PCAP.
Since the data in that field is not the flags, the PCAP that is created is
incorrect. So, my assuption was that the database would be holding the flags.

that doesn't sound too kosher... shouldn't a PCAP be the actual data on the 
wire? fragments and all?? yes, i understand that in some cases the fragments are 
reassembled into one large packet with flags and packet size supposedly adjusted 
to match but while this is a GoodThing<tm> in some cases, it would seem to be 
not all that proper in others...
