Dual rate support for private shaper. Valid only when private shaper is supported for the leaf nodes on this level. When non-zero, it indicates there is at least one leaf node on this level with dual rate private shaper support, which may not be the case for all the leaf nodes on this level.

Definition at line 522 of file rte_tm.h.
| uint32_t shaper_shared_n_max |
Maximum number of shared shapers that any non-leaf node on this level can be part of. The value of zero indicates that shared shapers are not supported by the non-leaf nodes on this level. When non-zero, it indicates there is at least one non-leaf node on this level that meets this condition, which may not be the case for all the non-leaf nodes on this level.
Maximum number of shared shapers that any leaf node on this level can be part of. The value of zero indicates that shared shapers are not supported by the leaf nodes on this level. When non-zero, it indicates there is at least one leaf node on this level that meets this condition, which may not be the case for all the leaf nodes on this level.
Definition at line 532 of file rte_tm.h.
| uint32_t sched_n_children_max |
Maximum number of children nodes. This parameter indicates that there is at least one non-leaf node on this level that can be configured with this many children nodes, which might not be true for all the non-leaf nodes on this level.
Definition at line 540 of file rte_tm.h.
| uint32_t sched_sp_n_priorities_max |
Maximum number of supported priority levels. This parameter indicates that there is at least one non-leaf node on this level that can be configured with this many priority levels for managing its children nodes, which might not be true for all the non-leaf nodes on this level. 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 on this level.
Definition at line 553 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. This parameter indicates there is at least one non-leaf node on this level that meets this condition, which may not be true for all the non-leaf nodes on this level. The value of zero is invalid. The value of 1 indicates that WFQ algorithm is not supported on this level. The maximum value is sched_n_children_max.
Definition at line 565 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. This parameter indicates there is at least one non-leaf node on this level that meets this condition, which might not be true for all the non-leaf nodes. The value of zero states that WFQ algorithm is not supported on this level. The value of 1 indicates that (sched_sp_n_priorities_max - 1) priority levels on this level 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 on this level. The maximum value is: min(floor(sched_n_children_max / 2), sched_sp_n_priorities_max).
Definition at line 584 of file rte_tm.h.
| uint32_t sched_wfq_weight_max |
Maximum WFQ weight. The value of 1 indicates that all sibling nodes on this level with same priority have the same WFQ weight, so on this level WFQ is reduced to FQ.
Definition at line 591 of file rte_tm.h.
Mask of statistics counter types supported by the non-leaf nodes on this level. Every supported statistics counter type is supported by at least one non-leaf node on this level, which may not be true for all the non-leaf nodes on this level.

Items valid only for the non-leaf nodes on this level.
| int cman_wred_packet_mode_supported |
WRED packet mode support. When non-zero, this parameter indicates that there is atleast one leaf node on this level that supports the WRED packet mode, which might not be true for all the leaf nodes. In packet mode, the WRED thresholds specify the queue length in packets, as opposed to bytes.
Definition at line 652 of file rte_tm.h.
| int cman_wred_byte_mode_supported |
WRED byte mode support. When non-zero, this parameter indicates that there is atleast one leaf node on this level that supports the WRED byte mode, which might not be true for all the leaf nodes. In byte mode, the WRED thresholds specify the queue length in bytes, as opposed to packets.
Definition at line 661 of file rte_tm.h.
| int cman_head_drop_supported |
Head drop algorithm support. When non-zero, this parameter indicates that there is at least one leaf node on this level that supports the head drop algorithm, which might not be true for all the leaf nodes on this level.
Definition at line 669 of file rte_tm.h.
| int cman_wred_context_private_supported |
Private WRED context support. When non-zero, it indicates there is at least one node on this level with private WRED context support, which may not be true for all the leaf nodes on this level.
Definition at line 676 of file rte_tm.h.
| uint32_t cman_wred_context_shared_n_max |
Maximum number of shared WRED contexts that any leaf node on this level can be part of. The value of zero indicates that shared WRED contexts are not supported by the leaf nodes on this level. When non-zero, it indicates there is at least one leaf node on this level that meets this condition, which may not be the case for all the leaf nodes on this level.
