int shaper_private_supported¶

Private shaper support for the current node.

Definition at line 797 of file rte_tm.h.

int shaper_private_dual_rate_supported¶

Dual rate shaping support for private shaper of current node. Valid only when private shaper is supported by the current node.

Definition at line 802 of file rte_tm.h.

uint64_t shaper_private_rate_min¶

Minimum committed/peak rate (bytes per second) for private shaper of current node. Valid only when private shaper is supported by the current node.

Definition at line 808 of file rte_tm.h.

uint64_t shaper_private_rate_max¶

Maximum committed/peak rate (bytes per second) for private shaper of current node. Valid only when private shaper is supported by the current node.

Definition at line 814 of file rte_tm.h.

int shaper_private_packet_mode_supported¶

Shaper private packet mode supported. When non-zero, this parameter indicates private shaper of current node can be configured with packet mode. When configured in packet mode, committed/peak rate provided is interpreted in packets per second.

Definition at line 821 of file rte_tm.h.

int shaper_private_byte_mode_supported¶

Shaper private byte mode supported. When non-zero, this parameter indicates private shaper of current node can be configured with byte mode. When configured in byte mode, committed/peak rate provided is interpreted in bytes per second.

Definition at line 828 of file rte_tm.h.

uint32_t shaper_shared_n_max¶

Maximum number of shared shapers the current node can be part of. The value of zero indicates that shared shapers are not supported by the current node.

Definition at line 834 of file rte_tm.h.

int shaper_shared_packet_mode_supported¶

Shaper shared packet mode supported. When non-zero, this parameter indicates that current node can be part of shared shapers which work in packet mode.

Definition at line 840 of file rte_tm.h.

int shaper_shared_byte_mode_supported¶

Shaper shared byte mode supported. When non-zero, this parameter indicates that current node can be part of shared shapers which work in byte mode.

Definition at line 846 of file rte_tm.h.

uint32_t sched_n_children_max¶

Maximum number of children nodes.

Definition at line 852 of file rte_tm.h.

uint32_t sched_sp_n_priorities_max¶

Maximum number of supported priority levels. The value of zero is invalid. The value of 1 indicates that only priority 0 is supported, which essentially means that Strict Priority (SP) algorithm is not supported.

Definition at line 860 of file rte_tm.h.

uint32_t sched_wfq_n_children_per_group_max¶

Maximum number of sibling nodes that can have the same priority at any given time, i.e. maximum size of the WFQ sibling node group. The value of zero is invalid. The value of 1 indicates that WFQ algorithm is not supported. The maximum value is sched_n_children_max.

Definition at line 869 of file rte_tm.h.

uint32_t sched_wfq_n_groups_max¶

Maximum number of priority levels that can have more than one child node at any given time, i.e. maximum number of WFQ sibling node groups that have two or more members. The value of zero states that WFQ algorithm is not supported. The value of 1 indicates that (sched_sp_n_priorities_max - 1) priority levels have at most one child node, so there can be only one priority level with two or more sibling nodes making up a WFQ group. The maximum value is: min(floor(sched_n_children_max / 2), sched_sp_n_priorities_max).

Definition at line 883 of file rte_tm.h.

uint32_t sched_wfq_weight_max¶

Maximum WFQ weight. The value of 1 indicates that all sibling nodes with same priority have the same WFQ weight, so WFQ is reduced to FQ.

Definition at line 889 of file rte_tm.h.

int sched_wfq_packet_mode_supported¶

WFQ packet mode supported. When non-zero, this parameter indicates that current node supports packet mode for WFQ among its children. WFQ weights will be applied against packet count for scheduling children when configured appropriately.

Definition at line 897 of file rte_tm.h.

int sched_wfq_byte_mode_supported¶

WFQ byte mode supported. When non-zero, this parameter indicates that current node supports byte mode for WFQ among its children. WFQ weights will be applied against bytes for scheduling children when configured appropriately.

Definition at line 905 of file rte_tm.h.

struct { ... } nonleaf¶

Items valid only for non-leaf nodes.

int cman_wred_packet_mode_supported¶

WRED packet mode support for current node.

Definition at line 912 of file rte_tm.h.

int cman_wred_byte_mode_supported¶

WRED byte mode support for current node.

Definition at line 915 of file rte_tm.h.

int cman_head_drop_supported¶

Head drop algorithm support for current node.

Definition at line 918 of file rte_tm.h.

int cman_wred_context_private_supported¶

Private WRED context support for current node.

Definition at line 921 of file rte_tm.h.

uint32_t cman_wred_context_shared_n_max¶

Maximum number of shared WRED contexts the current node can be part of. The value of zero indicates that shared WRED contexts are not supported by the current node.

Definition at line 928 of file rte_tm.h.

struct { ... } leaf¶

Items valid only for leaf nodes.

uint64_t stats_mask¶

Mask of statistics counter types supported by the current node.
