From 3d7cc2ba628dcc6b55a2bafc7eaf35019fdcc201 Mon Sep 17 00:00:00 2001 From: Pavel Emelyanov Date: Wed, 9 Jan 2008 00:33:11 -0800 Subject: [NETFILTER]: Switch to using ctl_paths in nf_queue and conntrack modules This includes the most simple cases for netfilter. The first part is tne queue modules for ipv4 and ipv6, on which the net/ipv4/ and net/ipv6/ paths are reused from the appropriate ipv4 and ipv6 code. The conntrack module is also patched, but this hunk is very small and simple. Signed-off-by: Pavel Emelyanov Acked-by: Patrick McHardy Signed-off-by: David S.
