Comment field in Chain

[alexwbaule]

Using the iptmon, and trying to do a dashboard in grafana, i think that "${PREFIX}" in the iptables|ip6tables in comment , its not necessary, because the tx and rx separation is made by the type (the chain, iptmon_tx and iptmon_rx).

I change it the script in my openwrt to not include the "prefix" and now i can do dashboards with splited or joined rx/tx, because the type_instance is the same (the rule name), and i can group by rule name/device.
