Hello,
pls find attached a patch file for reassemble.c/h & packet-tcp.c . The patch affects mainly these two funcs.

*fragment_add() defragments some data and once it's finished, the process can be continued by seting the FD_PARTIAL_REASSEMBLY flag. The code using fragment_add() should access this flag via fragment_set_partial_reassembly(). I tried to preserve the four error flags present in the function. The ones I think must be altered are FD_TOOLONGFRAGMENT and FD_MULTIPLETAILS.

*desegment_tcp() should be able now to handle extension requests from subdissectors, so now the subdissector can ask first for a desegment_offset and desegment_len. Once this request is completed, the subdissector can ask desegment_tcp to continue the process, using again desegment_offset and desegment_len vars. This can be repeated n times.

And thanks to Ronnie Sahlberg for the help.
Ricardo.
