From 3f87c08c615f567799b426aff0341ea8010a0ebb Mon Sep 17 00:00:00 2001 From: Pablo Neira Ayuso Date: Mon, 27 Nov 2017 22:29:52 +0100 Subject: netfilter: move route indirection to struct nf_ipv6_ops We cannot make a direct call to nf_ip6_route() because that would result in autoloading the 'ipv6' module because of symbol dependencies. Therefore, define route 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.
