  	  Stream Control Transmission Protocol
  
  	  From RFC 2960 <http://www.ietf.org/rfc/rfc2960.txt>.
  
  	  "SCTP is a reliable transport protocol operating on top of a
  	  connectionless packet network such as IP.  It offers the following
  	  services to its users:
  
  	  -- acknowledged error-free non-duplicated transfer of user data,
  	  -- data fragmentation to conform to discovered path MTU size,
  	  -- sequenced delivery of user messages within multiple streams,
  	  with an option for order-of-arrival delivery of individual user
  	  messages,
  	  -- optional bundling of multiple user messages into a single SCTP
  	  packet, and
  	  -- network-level fault tolerance through supporting of multi-
  	  homing at either or both ends of an association."
  
  	  To compile this protocol support as a module, choose M here: the

  	  module will be called sctp. Debug messages are handeled by the
  	  kernel's dynamic debugging framework.

  
  	  If in doubt, say N.

          This module allows for capturing the changes to SCTP association
          state in response to incoming packets. It is used for debugging
          SCTP congestion control algorithms. If you don't understand
          what was just said, you don't need it: say N.
