	  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.
