netfilter: move checksum indirection to struct nf_ipv6_ops
We cannot make a direct call to nf_ip6_checksum() because that would result in autoloading the 'ipv6' module because of symbol dependencies. Therefore, define checksum indirection in nf_ipv6_ops where this really belongs to. For IPv4, we can indeed make a direct function call, which is faster, given IPv4 is built-in in the networking code by default. Still, CONFIG_INET=n and CONFIG_NETFILTER=y is possible, so define empty inline stub for IPv4 in such case. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
