  17          From RFC 2960 <http://www.ietf.org/rfc/rfc2960.txt>.
  18
  19          "SCTP is a reliable transport protocol operating on top of a
  20          connectionless packet network such as IP.  It offers the following
  21          services to its users:
  22
  23          -- acknowledged error-free non-duplicated transfer of user data,
  24          -- data fragmentation to conform to discovered path MTU size,
  25          -- sequenced delivery of user messages within multiple streams,
  26          with an option for order-of-arrival delivery of individual user
  27          messages,
  28          -- optional bundling of multiple user messages into a single SCTP
  29          packet, and
  30          -- network-level fault tolerance through supporting of multi-
  31          homing at either or both ends of an association."
  32
  33          To compile this protocol support as a module, choose M here: the
  34          module will be called sctp.
  35
  36          If in doubt, say N.
