14	  Stream Control Transmission Protocol

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.
