Field Documentation

◆ n_max

uint32_t n_max

Maximum number of MTR objects.

Definition at line 249 of file rte_mtr.h.

◆ n_shared_max

uint32_t n_shared_max

Maximum number of MTR objects that can be shared by multiple flows. The value of zero indicates that shared MTR objects are not supported. The maximum value is n_max.

Definition at line 255 of file rte_mtr.h.

◆ identical

int identical

When non-zero, this flag indicates that all the MTR objects that cannot be shared by multiple flows have identical capability set.

Definition at line 260 of file rte_mtr.h.

◆ shared_identical

int shared_identical

When non-zero, this flag indicates that all the MTR objects that can be shared by multiple flows have identical capability set.

Definition at line 265 of file rte_mtr.h.

◆ shared_n_flows_per_mtr_max

uint32_t shared_n_flows_per_mtr_max

Maximum number of flows that can share the same MTR object. The value of zero is invalid. The value of 1 means that shared MTR objects not supported.

Definition at line 271 of file rte_mtr.h.

◆ chaining_n_mtrs_per_flow_max

uint32_t chaining_n_mtrs_per_flow_max

Maximum number of MTR objects that can be part of the same flow. The value of zero is invalid. The value of 1 indicates that MTR object chaining is not supported. The maximum value is n_max.

Definition at line 277 of file rte_mtr.h.

◆ chaining_use_prev_mtr_color_supported

int chaining_use_prev_mtr_color_supported

When non-zero, it indicates that the packet color identified by one MTR object can be used as the packet input color by any subsequent MTR object from the same flow. When zero, it indicates that the color determined by one MTR object is always ignored by any subsequent MTR object from the same flow. Only valid when MTR chaining is supported, i.e. chaining_n_mtrs_per_flow_max is greater than 1. When non-zero, it also means that the color aware mode is supported by at least one metering algorithm.

Definition at line 289 of file rte_mtr.h.

◆ chaining_use_prev_mtr_color_enforced

int chaining_use_prev_mtr_color_enforced

When non-zero, it indicates that the packet color identified by one MTR object is always used as the packet input color by any subsequent MTR object that is part of the same flow. When zero, it indicates that whether the color determined by one MTR object is either ignored or used as the packet input color by any subsequent MTR object from the same flow is individually configurable for each MTR object. Only valid when chaining_use_prev_mtr_color_supported is non-zero.

Definition at line 300 of file rte_mtr.h.

◆ meter_srtcm_rfc2697_n_max

uint32_t meter_srtcm_rfc2697_n_max

Maximum number of MTR objects that can have their meter configured to run the srTCM RFC 2697 algorithm. The value of 0 indicates this metering algorithm is not supported. The maximum value is n_max.

Definition at line 306 of file rte_mtr.h.

◆ meter_trtcm_rfc2698_n_max

uint32_t meter_trtcm_rfc2698_n_max

Maximum number of MTR objects that can have their meter configured to run the trTCM RFC 2698 algorithm. The value of 0 indicates this metering algorithm is not supported. The maximum value is n_max.

Definition at line 312 of file rte_mtr.h.

◆ meter_trtcm_rfc4115_n_max

uint32_t meter_trtcm_rfc4115_n_max

Maximum number of MTR objects that can have their meter configured to run the trTCM RFC 4115 algorithm. The value of 0 indicates this metering algorithm is not supported. The maximum value is n_max.

Definition at line 318 of file rte_mtr.h.

◆ meter_rate_max

uint64_t meter_rate_max

Maximum traffic rate that can be metered by a single MTR object. For srTCM RFC 2697, this is the maximum CIR rate. For trTCM RFC 2698, this is the maximum PIR rate. For trTCM RFC 4115, this is the maximum value for the sum of PIR and EIR rates.

Definition at line 325 of file rte_mtr.h.

◆ color_aware_srtcm_rfc2697_supported

int color_aware_srtcm_rfc2697_supported

When non-zero, it indicates that color aware mode is supported for the srTCM RFC 2697 metering algorithm.

Definition at line 331 of file rte_mtr.h.

◆ color_aware_trtcm_rfc2698_supported

int color_aware_trtcm_rfc2698_supported

When non-zero, it indicates that color aware mode is supported for the trTCM RFC 2698 metering algorithm.

Definition at line 337 of file rte_mtr.h.

◆ color_aware_trtcm_rfc4115_supported

int color_aware_trtcm_rfc4115_supported

When non-zero, it indicates that color aware mode is supported for the trTCM RFC 4115 metering algorithm.

Definition at line 343 of file rte_mtr.h.

◆ policer_action_recolor_supported

int policer_action_recolor_supported

When non-zero, it indicates that the policer packet recolor actions are supported.

See also
enum rte_mtr_policer_action

Definition at line 349 of file rte_mtr.h.

◆ policer_action_drop_supported

int policer_action_drop_supported

When non-zero, it indicates that the policer packet drop action is supported.

See also
enum rte_mtr_policer_action

Definition at line 355 of file rte_mtr.h.

◆ stats_mask

uint64_t stats_mask

Set of supported statistics counter types.

See also
enum rte_mtr_stats_type

Definition at line 360 of file rte_mtr.h.
