9 depends on IPV6 || IPV6=n
15 Stream Control Transmission Protocol
17 From RFC 2960 <http://www.ietf.org/rfc/rfc2960.txt>.
19 "SCTP is a reliable transport protocol operating on top of a
20 connectionless packet network such as IP. It offers the following
21 services to its users:
23 -- acknowledged error-free non-duplicated transfer of user data,
24 -- data fragmentation to conform to discovered path MTU size,
25 -- sequenced delivery of user messages within multiple streams,
26 with an option for order-of-arrival delivery of individual user
28 -- optional bundling of multiple user messages into a single SCTP
30 -- network-level fault tolerance through supporting of multi-
31 homing at either or both ends of an association."
33 To compile this protocol support as a module, choose M here: the
34 module will be called sctp. Debug messages are handled by the
35 kernel's dynamic debugging framework.
41 config SCTP_DBG_OBJCNT
42 bool "SCTP: Debug object counts"
45 If you say Y, this will enable debugging support for counting the
46 type of objects that are currently allocated. This is useful for
47 identifying memory leaks. This debug information can be viewed by
48 'cat /proc/net/sctp/sctp_dbg_objcnt'
52 prompt "Default SCTP cookie HMAC encoding"
53 default SCTP_DEFAULT_COOKIE_HMAC_MD5
55 This option sets the default sctp cookie hmac algorithm
