You also need to look at how a 'user' can actually get SCTP to
merge data chunks in the first place.
With Nagle disabled (and it probably has to be since the data flow
is unlikely to be 'command-response' or 'unidirectional bulk')
it is currently almost impossible to get more than one chunk
into an ethernet frame.
Support for MSG_MORE would help.
Given the current implementation you can get almost the required
behaviour by turning nagle off and on repeatedly.
I did wonder whether the queued data could actually be picked up
be a Heartbeat chunk that is probing a different remote address
(which would be bad news).
