  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.

  51           If you say Y, this will enable debugging support for counting the
  52           type of objects that are currently allocated.  This is useful for
  53           identifying memory leaks.   If the /proc filesystem is enabled this
  54           debug information can be viewed by
  55           'cat /proc/net/sctp/sctp_dbg_objcnt'
