how to see marker value in syslog

[Marek Nawa <mnawa@sst.pl>]

Hi,
I'm using on my server Debian stable with iptables. I've configure 
traffic control (command tc from iproute2) based on filter fw (marked 
packages from iptables). I have advanced router with failover and 4 
network interfaces and I had to define more than one marking rule.
e.g.
iptables -A PREROUTING -t mangle -i eth0 -j MARK --set-mark 10

I've defined too rule for loggin results:
iptables -t mangle -A PREROUTING -i eth0 -m limit --limit 1/s -j LOG 
--log-prefix "mark testMN prerouting 10 " --log-level debug 
--log-ip-options --log-tcp-options

and I've found in syslog

Mar 28 14:50:11 routerUbuntu kernel: mark testMN prerouting 10 IN=eth0 
OUT= MAC=00:0e:0c:7f:2a:7f:00:c0:7b:a2:e7:06:08:00 SRC

but I can't find iformation about my marker value 10.
Please give me a solution, how can I investigate in log files packages 
with their marker-value.
