  15
  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."
  31
  32           To compile this protocol support as a module, choose M here: the
  33           module will be called sctp. Debug messages are handeled by the
  34           kernel's dynamic debugging framework.
  35
  36           If in doubt, say N.
