Maximum number of nodes.
Definition at line 239 of file rte_tm.h.
Maximum number of levels (i.e. number of nodes connecting the root node with any leaf node, including the root and the leaf).
Definition at line 244 of file rte_tm.h.
| int non_leaf_nodes_identical |
When non-zero, this flag indicates that all the non-leaf nodes (with the exception of the root node) have identical capability set.
Definition at line 249 of file rte_tm.h.
When non-zero, this flag indicates that all the leaf nodes have identical capability set.
Definition at line 254 of file rte_tm.h.
Maximum number of shapers, either private or shared. In case the implementation does not share any resources between private and shared shapers, it is typically equal to the sum of shaper_private_n_max and shaper_shared_n_max. The value of zero indicates that traffic shaping is not supported.
Definition at line 262 of file rte_tm.h.
| uint32_t shaper_private_n_max |
Maximum number of private shapers. Indicates the maximum number of nodes that can concurrently have their private shaper enabled. The value of zero indicates that private shapers are not supported.
Definition at line 268 of file rte_tm.h.
| int shaper_private_dual_rate_n_max |
Maximum number of private shapers that support dual rate shaping. Indicates the maximum number of nodes that can concurrently have their private shaper enabled with dual rate support. Only valid when private shapers are supported. The value of zero indicates that dual rate shaping is not available for private shapers. The maximum value is shaper_private_n_max.
Definition at line 277 of file rte_tm.h.
| uint64_t shaper_private_rate_min |
Minimum committed/peak rate (bytes per second) for any private shaper. Valid only when private shapers are supported.
Definition at line 282 of file rte_tm.h.
| uint64_t shaper_private_rate_max |
Maximum committed/peak rate (bytes per second) for any private shaper. Valid only when private shapers are supported.
Definition at line 287 of file rte_tm.h.
| uint32_t shaper_shared_n_max |
Maximum number of shared shapers. The value of zero indicates that shared shapers are not supported.
Definition at line 292 of file rte_tm.h.
| uint32_t shaper_shared_n_nodes_per_shaper_max |
Maximum number of nodes that can share the same shared shaper. Only valid when shared shapers are supported.
Definition at line 297 of file rte_tm.h.
| uint32_t shaper_shared_n_shapers_per_node_max |
Maximum number of shared shapers a node can be part of. This parameter indicates that there is at least one node that can be configured with this many shared shapers, which might not be true for all the nodes. Only valid when shared shapers are supported, in which case it ranges from 1 to shaper_shared_n_max.
Definition at line 305 of file rte_tm.h.
| uint32_t shaper_shared_dual_rate_n_max |
Maximum number of shared shapers that can be configured with dual rate shaping. The value of zero indicates that dual rate shaping support is not available for shared shapers.
Definition at line 311 of file rte_tm.h.
| uint64_t shaper_shared_rate_min |
Minimum committed/peak rate (bytes per second) for any shared shaper. Only valid when shared shapers are supported.
Definition at line 316 of file rte_tm.h.
| uint64_t shaper_shared_rate_max |
Maximum committed/peak rate (bytes per second) for any shared shaper. Only valid when shared shapers are supported.
Definition at line 321 of file rte_tm.h.
| int shaper_pkt_length_adjust_min |
Minimum value allowed for packet length adjustment for any private or shared shaper.
Definition at line 326 of file rte_tm.h.
| int shaper_pkt_length_adjust_max |
Maximum value allowed for packet length adjustment for any private or shared shaper.
Definition at line 331 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 that can be configured with this many children nodes, which might not be true for all the non-leaf nodes.
Definition at line 338 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 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. 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 348 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 that meets this condition, which might not be true for all the non-leaf nodes. 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 358 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 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. 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 371 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 376 of file rte_tm.h.
| int cman_wred_packet_mode_supported |
WRED packet mode support. When non-zero, this parameter indicates that there is atleast one leaf node 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 384 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 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 392 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 that supports the head drop algorithm, which might not be true for all the leaf nodes.
Definition at line 398 of file rte_tm.h.
| uint32_t cman_wred_context_n_max |
Maximum number of WRED contexts, either private or shared. In case the implementation does not share any resources between private and shared WRED contexts, it is typically equal to the sum of cman_wred_context_private_n_max and cman_wred_context_shared_n_max. The value of zero indicates that WRED is not supported.
Definition at line 407 of file rte_tm.h.
| uint32_t cman_wred_context_private_n_max |
Maximum number of private WRED contexts. Indicates the maximum number of leaf nodes that can concurrently have their private WRED context enabled. The value of zero indicates that private WRED contexts are not supported.
Definition at line 414 of file rte_tm.h.
| uint32_t cman_wred_context_shared_n_max |
Maximum number of shared WRED contexts. The value of zero indicates that shared WRED contexts are not supported.
Definition at line 419 of file rte_tm.h.

Maximum number of leaf nodes that can share the same WRED context. Only valid when shared WRED contexts are supported.
Definition at line 424 of file rte_tm.h.
| uint32_t cman_wred_context_shared_n_contexts_per_node_max |
Maximum number of shared WRED contexts a leaf node can be part of. This parameter indicates that there is at least one leaf node that can be configured with this many shared WRED contexts, which might not be true for all the leaf nodes. Only valid when shared WRED contexts are supported, in which case it ranges from 1 to cman_wred_context_shared_n_max.
