    I have some questions about cbq. Why are transfers so radical when limiting
    "korenje upload" to 512kbit. when watching with dumeter, the transfers are
    sometimes 600kbit/s, sometimes 300kbit/s but average still around
    480kbit/s... when I set limits to 256kbit the transfers are steady, I see
    smooth line on du-meter.
    second problem is, why limiting internet traffic sent to local linux won't
    work? I can see packets being marked so it should work, but it doesn't.
