| 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.
| int shaper_shared_packet_mode_supported |
Shaper shared packet mode supported. When non-zero, this parameter indicates that there is at least one non-leaf node on this level that can be part of shared shapers which work in packet mode.
Shaper shared packet mode supported. When non-zero, this parameter indicates that there is at least one leaf node on this level that can be part of shared shapers which work in packet mode.
| int shaper_shared_byte_mode_supported |
Shaper shared byte mode supported. When non-zero, this parameter indicates that there is at least one non-leaf node on this level that can be part of shared shapers which work in byte mode.

| uint32_t sched_n_children_max |
| 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.
| 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.
| 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).
| uint32_t sched_wfq_weight_max |
| int sched_wfq_packet_mode_supported |
WFQ packet mode supported. When non-zero, this parameter indicates that there is at least one non-leaf node at this level that supports packet mode for WFQ among its children. WFQ weights will be applied against packet count for scheduling children when a non-leaf node is configured appropriately.
| int sched_wfq_byte_mode_supported |
WFQ byte mode supported. When non-zero, this parameter indicates that there is at least one non-leaf node at this level that supports byte mode for WFQ among its children. WFQ weights will be applied against bytes for scheduling children when a non-leaf node is configured appropriately.
| uint64_t stats_mask |
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.
Mask of statistics counter types supported by the leaf nodes on this level. Every supported statistics counter type is supported by at least one leaf node on this level, which may not be true for all the leaf nodes on this level.
| struct { ... } nonleaf |
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 at least 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.
| int cman_wred_byte_mode_supported |
WRED byte mode support. When non-zero, this parameter indicates that there is at least 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.

| int cman_wred_context_private_supported |
| 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.
| struct { ... } leaf |
Items valid only for the leaf nodes on this level.
