Dear all,

I want to add SCTP support in the 'Decode as' dialog. The src/dst
port stuff os easy to handle, because you know the src/dst port
of of the selected packet from the packet_info structure.

For SCTP it would also be very helpful to change the dissector
for the PPID field included in every DATA chunk. But there can
be more than 1 DATA chunk in one SCTP packet. How can I know
in the 'decode as' code, which PPIDs are present in the packet?
One possibility is to add an array of PPIDs to the packet_info
structure and fill that in the SCTP dissector. This would give
the information for the first N DATA chunks. A large N would
require a lot of memory, but, let us say N = 4, would be a compromise.
So is this acceptable, or is there even a better solution to the
problem?

Best regards
Michael
