IPV6=m
DEFRAG_IPV6=m
CONNTRACK=y yields:
net/netfilter/nf_conntrack_proto.o: In function `nf_ct_netns_do_get':
net/netfilter/nf_conntrack_proto.c:802: undefined reference to `nf_defrag_ipv6_enable'
net/netfilter/nf_conntrack_proto.o:(.rodata+0x640): undefined reference to `nf_conntrack_l4proto_icmpv6'
After previous patch, DEFRAG_IPV6 and IPV6 are no longer retain any
dependencies, so we can tell Kconfig DEFRAG_IPV6 needs to be built-in as
well, this resolves missing nf_defrag_ipv6_enable.
Second error can be fixed via makefile, just make sure conntrack_proto_ipv6
is part of conntrack module.
based on earlier patch from Arnd Bergmann.
