dummynet trick

[Laszlo Zsolt Nagy]

Hello,

This is the beginning of my script:

ipfw -q flush
ipfw pipe 1 config bw 729kbit/s
ipfw pipe 2 config bw 121kbit/s
ipfw queue 1 config pipe 1 weight 94
ipfw queue 2 config pipe 1 weight 5
ipfw queue 3 config pipe 1 weight 1
ipfw queue 4 config pipe 2 weight 94
ipfw queue 5 config pipe 2 weight 5
ipfw queue 6 config pipe 2 weight 1

Everything runs okay except this:

    ipfw queue 3 config pipe 1 weight 1

results in:

   ipfw: setsockopt(IP_DUMMYNET_CONFIGURE): Invalid argument

But when I change to this:

    ipfw queue 22 config pipe 1 weight 1

then it works just fine. What the hell is this?
