From cbc9f2f4fcd70d5a627558ca9a881fa9391abf69 Mon Sep 17 00:00:00 2001 From: Patrick McHardy Date: Fri, 23 Dec 2011 13:59:49 +0100 Subject: [PATCH] netfilter: nf_nat: export NAT definitions to userspace Export the NAT definitions to userspace. So far userspace (specifically, iptables) has been copying the headers files from include/net. Also rename some structures and definitions in preparation for IPv6 NAT. Since these have never been officially exported, this doesn't affect existing userspace code.
