hello Nikolay Kichukov, Thank you for your help, I have fixed the problem now. I'm not using the tc in a computer, I port the tc to a embedded system, a router runing linux, and I want to control the traffic on LAN, and the WAN is connnect to the Internet by PPPoE. Today I debugged in the linux net/sched/ code and found a bug in the include/net/pkt_cls.h->tc_classify(). when I use PPPoE to access Internet by WAN, the skb->protocol is 0x8864 which is means a PPPoE session packet, so it dose not match the protocol ip which given in the filter, and all the packets will not by classified by the filter.
