Description Xin Long 2022-05-24 13:13:47 UTC 
Linux SCTP has added a couple of new types of CHUNKs in recent years, but they're not supported in tcpdump. Such as:

I-DATA and I-FORWARD-TSN chunks from RFC8260
RE-CONFIG Chunk from RFC6525

We need to add them into tcpdump and parse these packets properly when capturing SCTP packets with tcpdump.

please try to implement it on:

https://github.com/the-tcpdump-group/tcpdump.git

Thanks.

Moving to 9.3.0, still waiting for the Upstream to merge.
