That is completely valid... Implementations are free to fragment user
data and bundle the fragments in one packet. There are even conditions
where
this is required behaviour.
Hmmm, like when (besides retransmission)? It certainly is ugly to look at.
BTW, I also mean to check if the SCTP dissector should be catching
exceptions whenever calling a subdissector. What I fixed above was
causing me massive confusion because the peer was SACKing TSNs I
couldn't see in the trace (because M3UA exception'd out). Of course
exceptions may occur for other reasons and we should never forgot to
display all the DATA chunks.
