From f7dcbe2f36a660140ecb286e15f502028d96ffdf Mon Sep 17 00:00:00 2001 From: Pablo Neira Ayuso Date: Wed, 20 Dec 2017 16:04:18 +0100 Subject: netfilter: move checksum_partial indirection to struct nf_ipv6_ops We cannot make a direct call to nf_ip6_checksum_partial() because that would result in autoloading the 'ipv6' module because of symbol dependencies. Therefore, define checksum_partial 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.
