You still need to enable sctp notifications (I think the patch deleted
that code).
Otherwise you don't get any kind of indication if the remote system
'resets' (ie sends an new INIT chunk) on an existing connection.
It is probably enough to treat the MSG_NOTIFICATION as a fatal error
and close the socket.
This is probably a bug in the sctp stack - if a connection is reset
but the user hasn't requested notifications then it should be
converted to a disconnect indication and a new incoming connection.
