Field Documentation

int shaper_private_supported

Private shaper support for the current node.

Definition at line 670 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 675 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 681 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 687 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 693 of file rte_tm.h.

uint32_t sched_n_children_max

Maximum number of children nodes.

Definition at line 700 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 708 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 717 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 731 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 737 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 743 of file rte_tm.h.

int cman_wred_byte_mode_supported

WRED byte mode support for current node.

Definition at line 746 of file rte_tm.h.

int cman_head_drop_supported

Head drop algorithm support for current node.

Definition at line 749 of file rte_tm.h.

int cman_wred_context_private_supported

Private WRED context support for current node.

Definition at line 752 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 759 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.
