  16           From RFC 2960 <http://www.ietf.org/rfc/rfc2960.txt>.
  17
  18           "SCTP is a reliable transport protocol operating on top of a
  19           connectionless packet network such as IP.  It offers the following
  20           services to its users:
  21
  22           -- acknowledged error-free non-duplicated transfer of user data,
  23           -- data fragmentation to conform to discovered path MTU size,
  24           -- sequenced delivery of user messages within multiple streams,
  25           with an option for order-of-arrival delivery of individual user
  26           messages,
  27           -- optional bundling of multiple user messages into a single SCTP
  28           packet, and
  29           -- network-level fault tolerance through supporting of multi-
  30           homing at either or both ends of an association."

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

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