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.

config NET_SCTPPROBE
tristate "SCTP: Association probing"
depends on PROC_FS && KPROBES
---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
what was just said, you don't need it: say N.
To compile this code as a module, choose M here: the
module will be called sctp_probe.
config SCTP_DBG_TSNS
bool "SCTP: Debug transactions"
help
If you say Y, this will enable transaction debugging, visible
from the kernel's dynamic debugging framework.
If unsure, say N. However, if you are running into problems, use
this option to gather outqueue trace information.
config SCTP_DBG_OBJCNT
bool "SCTP: Debug object counts"
depends on PROC_FS
help
If you say Y, this will enable debugging support for counting the
type of objects that are currently allocated. This is useful for
identifying memory leaks. This debug information can be viewed by
'cat /proc/net/sctp/sctp_dbg_objcnt'
If unsure, say N
