From 1d49144c0aaa61be4e3ccbef9cc5c40b0ec5f2fe Mon Sep 17 00:00:00 2001 From: Patrick McHardy Date: Fri, 3 Jan 2014 12:16:16 +0000 Subject: netfilter: nf_tables: add "inet" table for IPv4/IPv6 This patch adds a new table family and a new filter chain that you can use to attach IPv4 and IPv6 rules. This should help to simplify rule-set maintainance in dual-stack setups.
