The API shouldn't change like this at all.
Is this from the RFC or elsewhere??

If the structure changes the socket option name and value
should also change.

IMHO large chunks of the sctp rfc are just horrid.
In particular all the places where is states that API functions are
implemented using setsockopt() - that should be an implementation detail.
Also ISTR that some of the structures are defined to have holes in them...
