Hi,
I have a question about dpdk qos feature, in rte_sched.h,
/** Port configuration parameters. */
struct rte_sched_port_params {
const char *name; /**< String to be associated */
int socket; /**< CPU socket ID */
uint32_t rate; /**< Output port rate
* (measured in bytes per second) */
uint32_t mtu; /**< Maximum Ethernet frame
size
* (measured in bytes).
* Should not include the framing overhead. */
uint32_t frame_overhead; /**< Framing overhead per
packet
* (measured in bytes) */
uint32_t n_subports_per_port; /**< Number of subports */
uint32_t n_pipes_per_subport; /**< Number of pipes per
subport */
uint16_t qsize[RTE_SCHED_TRAFFIC_CLASSES_PER_PIPE];
/**< Packet queue size for each traffic class.
* All queues within the same pipe traffic class have the same
* size. Queues from different pipes serving the same traffic
* class have the same size. */
struct rte_sched_pipe_params *pipe_profiles;
/**< Pipe profile table.
* Every pipe is configured using one of the profiles from this
table. */
uint32_t n_pipe_profiles; /**< Profiles in the pipe
profile table */
#ifdef RTE_SCHED_RED
struct rte_red_params
red_params[RTE_SCHED_TRAFFIC_CLASSES_PER_PIPE][e_RTE_METER_COLORS]; /**< RED
parameters */
#endif
};
rate is type of uint32_t, but if physical port rate is 40G
bit/s, which is 5G byte/s, 5G already exceed the max value of uint32_t, so I
doult that 40G is not supported by dpdk qos lib, or any error of my
understanding?
Thanks and waiting for your reply!
BRs,
Kevin
