+ 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.

+ ---help---
+ 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
