    ipv6: remove dependency of nf_defrag_ipv6 on ipv6 module · 70b095c8
    Florian Westphal authored
    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'
    
    Setting DEFRAG_IPV6=y causes undefined references to ip6_rhash_params
    ip6_frag_init and ip6_expire_frag_queue so it would be needed to force
    IPV6=y too.
    
    This patch gets rid of the 'followup linker error' by removing
    the dependency of ipv6.ko symbols from netfilter ipv6 defrag.
    
    Shared code is placed into a header, then used from both.
