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].
