Maintaining a modular IPv6 stack offers image size savings for specific setups, this benefit is outweighed by the architectural burden it imposes on the subsystems on implementation and maintenance. Therefore, drop it. Change CONFIG_IPV6 from tristate to bool. Remove all Kconfig dependencies across the tree that explicitly checked for IPV6=m. In addition, remove MODULE_DESCRIPTION(), MODULE_ALIAS(), MODULE_AUTHOR() and MODULE_LICENSE(). This is also replacing module_init() by device_initcall(). It is not possible to use fs_initcall() as IPv4 does because that creates a race condition on IPv6 addrconf. Finally, modify the default configs from CONFIG_IPV6=m to CONFIG_IPV6=y except for m68k as according to the bloat-o-meter the image is increasing by 330KB~ and that isn't acceptable. Instead, disable IPv6 on this architecture by default. This is aligned with m68k RAM requirements and recommendations [1].

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 handled by the
|
|
kernel's dynamic debugging framework.
|
|
|
|
If in doubt, say N.

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
