Now my question is if we have have a UDP packet compiling fragmented IP
packets eg: Frame no. 33 of attached file. With the statement
"tvb->ds_tvb" we can get access to parent-level tvb. But for fragmented
and compiled frames as no. 33 this does not work. So for such fragmented
and compiled packets how to get the parent level tvb.
What do you mean by "the parent-level tvb"?
If IP reassembly is enabled, the *only* tvbuff handed to the UDP
dissector is a tvbuff containing the payload of the reassembled IP
datagram. You do not have access to the tvbuffs - plural! - for the IP
fragments that were reassembled.
What information do you need from the IP layer?
