I set the rate as 10mbit, 20mbit, 30mbit for easy measuring. when I set the classid to 0x10010, class 1:10's packet count was increased. But, according to your configuration, every packet has to flowed to 1:10 class. Of course I know that the net_cls can't classify all packet because of the getting classid from the current task. Even though we consider it, Many packets are flowed to 1:30 class. therefore, the rate of the socket showed about 30mbps. This is the 1:30 class's rate. I think it's because that 1:30 class is the default class. When I changed the default to 20, the rate was varied to 20mbps, class 1:20's rate. To measure this rate, I used the iperf and scp command. Two results are the same. How about your experiment's result? Would you check the accurate rate of the network using applications like a iperf? By the results of my experiments, net_cls couldn't control the network rate of the group.
