Process payload fragment_add_check() does "heavy lifting" of reassembly • The first time this packet is seen: • Just returns NULL if fragment cut short by snaplen • Adds to reassembly based on pinfo->src, pinfo->dst, id • If all fragments found, saves as finished reassembly and returns fragment_data * for finished reassembly • Otherwise, returns NULL OK Save and apply the changes and close the dialog box, see Appendix B, Files and Folders for details.
