	  Stream Control Transmission Protocol

	  From RFC 2960 <http://www.ietf.org/rfc/rfc2960.txt>.

	  "SCTP is a reliable transport protocol operating on top of a
	  connectionless packet network such as IP.  It offers the following
	  services to its users:

	  -- acknowledged error-free non-duplicated transfer of user data,
	  -- data fragmentation to conform to discovered path MTU size,
	  -- sequenced delivery of user messages within multiple streams,
	  with an option for order-of-arrival delivery of individual user
	  messages,
	  -- optional bundling of multiple user messages into a single SCTP
	  packet, and
	  -- network-level fault tolerance through supporting of multi-
	  homing at either or both ends of an association."

	  To compile this protocol support as a module, choose M here: the
	  module will be called sctp.

	  If in doubt, say N.

        This module allows for capturing the changes to SCTP association
        state in response to incoming packets. It is used for debugging
        SCTP congestion control algorithms. If you don't understand
