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

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

  43           If you say Y, this will enable verbose debugging messages.

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

  66           is strongly recommended to use HMAC-SHA1 or HMAC-MD5.  See
