From 535b57c7c1524125444aa1b874332f6ff1608ef5 Mon Sep 17 00:00:00 2001 From: Patrick McHardy Date: Mon, 14 Apr 2008 11:15:47 +0200 Subject: [PATCH] [NETFILTER]: nf_nat: move NAT ctnetlink helpers to nf_nat_proto_common Move to nf_nat_proto_common and rename to nf_nat_proto_... since they're also used by protocols that don't have port numbers.
