Thanks for your answer! But i haved not understand it.
what is the role of traffic class in subport, and the relationship with the traffic class in pipe ?
The traffic class in function of rte_sched_port_pkt_write is subport's or pipe's ?
void rte_sched_port_pkt_write(struct rte_mbuf *pkt,
uint32_t subport, uint32_t pipe, uint32_t traffic_class,
uint32_t queue, enum rte_meter_color color);

There are 4x traffic classes. You can enforce a limit on the amount of traffic belonging to each traffic class at the subport level, as well as at the level of each pipe if you want.
