    Well, to be honest - that's _exactly_ what I did. I've already figured
    out that traffic in Linux is counted by device driver, and there is no
    way to do it my way.
    But this is the right way or... in the future, maybe I'll try
    ipt_account patch which is already present in cvs patch-o-matic-ng.
