Subject: netfilter 01/29: xt_NFLOG: don't call nf_log_packet in NFLOG module.
commit 5f7340eff8f68f41b7e5c7ad47ec4cd1ea1afb40
Author: Eric Leblond <eric@....fr>
Date: Tue Nov 4 14:21:08 2008 +0100
netfilter: xt_NFLOG: don't call nf_log_packet in NFLOG module.
This patch modifies xt_NFLOG to suppress the call to nf_log_packet()
function. The call of this wrapper in xt_NFLOG was causing NFLOG to
use the first initialized module. Thus, if ipt_ULOG is loaded before
nfnetlink_log all NFLOG rules are treated as plain LOG rules.
