Field Documentation uint32_t n_nodes_max Maximum number of nodes. Definition at line 201 of file rte_tm.h. uint32_t n_levels_max 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 206 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 211 of file rte_tm.h. int leaf_nodes_identical When non-zero, this flag indicates that all the leaf nodes have identical capability set. Definition at line 216 of file rte_tm.h. uint32_t shaper_n_max Maximum number of shapers, either private or shared. In case the implemen- tation 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 224 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 230 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 sup- ported. 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 239 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 244 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 249 of file rte_tm.h. int shaper_private_packet_mode_supported Shaper private packet mode supported. When non-zero, this parameter indi- cates that there is at least one node that can be configured with packet mode in its private shaper. When shaper is configured in packet mode, com- mitted/peak rate provided is interpreted in packets per second. Definition at line 257 of file rte_tm.h. int shaper_private_byte_mode_supported Shaper private byte mode supported. When non-zero, this parameter indicates that there is at least one node that can be configured with byte mode in its private shaper. When shaper is configured in byte mode, committed/peak rate provided is interpreted in bytes per second. Definition at line 265 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 271 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 276 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 in- dicates 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 284 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 290 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 295 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 300 of file rte_tm.h. int shaper_shared_packet_mode_supported Shaper shared packet mode supported. When non-zero, this parameter indi- cates a shared shaper can be configured with packet mode. When shared shaper is configured in packet mode, committed/peak rate provided is inter- preted in packets per second. Definition at line 307 of file rte_tm.h. int shaper_shared_byte_mode_supported Shaper shared byte mode supported. When non-zero, this parameter indicates that a shared shaper can be configured with byte mode. When shared shaper is configured in byte mode, committed/peak rate provided is interpreted in bytes per second. Definition at line 314 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 320 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 325 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 332 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 342 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 352 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 sup- ported. The value of 1 indicates that (sched_sp_n_priorities_max - 1) pri- ority 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 365 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 370 of file rte_tm.h. 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 that supports packet mode for WFQ among its children. WFQ weights will be applied against packet count for schedul- ing children when a non-leaf node is configured appropriately. Definition at line 378 of file rte_tm.h. 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 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. Definition at line 386 of file rte_tm.h. int cman_wred_packet_mode_supported WRED packet mode support. When non-zero, this parameter indicates that there is at least one leaf node that supports the WRED packet mode, which might not be true for all the leaf nodes. In packet mode, the WRED thresh- olds specify the queue length in packets, as opposed to bytes. Definition at line 394 of file rte_tm.h. int cman_wred_byte_mode_supported WRED byte mode support. When non-zero, this parameter indicates that there is at least 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 402 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 408 of file rte_tm.h. uint32_t cman_wred_context_n_max Maximum number of WRED contexts, either private or shared. In case the im- plementation does not share any resources between private and shared WRED contexts, it is typically equal to the sum of cman_wred_context_pri- vate_n_max and cman_wred_context_shared_n_max. The value of zero indicates that WRED is not supported. Definition at line 417 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 424 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 429 of file rte_tm.h. uint32_t cman_wred_context_shared_n_nodes_per_context_max Maximum number of leaf nodes that can share the same WRED context. Only valid when shared WRED contexts are supported. Definition at line 434 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 pa- rameter indicates that there is at least one leaf node that can be config- ured 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.
