Subject[PATCH] netfilter/iptables: Fix log-level processing
From
Date
auto75914331@hushmail.com reports that iptables does not correctly
output the KERN_<level>.

$IPTABLES -A RULE_0_in -j LOG --log-level notice --log-prefix "DENY in: "

result with linux 3.6-rc5
Sep 12 06:37:29 xxxxx kernel: <5>DENY in: IN=eth0 OUT= MAC=.......

result with linux 3.5.3 and older:
Sep 9 10:43:01 xxxxx kernel: DENY in: IN=eth0 OUT= MAC......

commit 04d2c8c83d0
("printk: convert the format for KERN_<LEVEL> to a 2 byte pattern")
updated the syslog header style but did not update netfilter uses.

Do so.
