Parameters for each traffic metering & policing object
| int use_prev_mtr_color |
Meter input color in case of MTR object chaining. When non-zero: if a previous MTR object is enabled in the same flow, then the color determined by the latest MTR object in the same flow is used as the input color by the current MTR object, otherwise the current MTR object uses the dscp_table to determine the input color. When zero: the color determined by any previous MTR object in same flow is ignored by the current MTR object, which uses the dscp_table to determine the input color.
| enum rte_mtr_color* dscp_table |
Meter input color. When non-NULL: it points to a pre-allocated and pre-populated table with exactly 64 elements providing the input color for each value of the IPv4/IPv6 Differentiated Services Code Point (DSCP) input packet field. When NULL: it is equivalent to setting this parameter to an all-green populated table (i.e. table with all the 64 elements set to green color). The color blind mode is configured by setting use_prev_mtr_color to 0 and dscp_table to either NULL or to an all-green populated table. When use_prev_mtr_color is non-zero value or when dscp_table contains at least one yellow or red color element, then the color aware mode is configured.
| int meter_enable |
Non-zero to enable the meter, zero to disable the meter at the time of MTR object creation. Ignored when the meter profile indicated by meter_profile_id is set to NONE.
| enum rte_mtr_policer_action action[RTE_MTR_COLORS] |
| uint64_t stats_mask |
Set of stats counters to be enabled.
