Member Function Documentation

   STAILQ_ENTRY (rte_graph_feature_register )
       Pointer to next registered feature in the same arc.

Field Documentation

   const char* arc_name
       Name of the arc which is registered either via RTE_GRAPH_FEATURE_ARC_REGISTER() or via
       rte_graph_feature_arc_create()

       Definition at line 247 of file rte_graph_feature_arc.h.

   const char* feature_name
       Name of the feature

       Definition at line 250 of file rte_graph_feature_arc.h.

   rte_node_t feature_node_id
       Node id of feature_node.

       Setting this field can be skipped if registering feature via RTE_GRAPH_FEATURE_REGISTER()

       Definition at line 258 of file rte_graph_feature_arc.h.

   rte_node_process_t feature_process_fn
       Feature node process() function calling feature fast path APIs.

       If application calls rte_graph_feature_arc_init(), node->process() provided in RTE_NODE_REGISTER() is
       overwritten by this function.

       Definition at line 267 of file rte_graph_feature_arc.h.

   struct rte_node_register* feature_node
       Pointer to Feature node registration

       Used when features are registered via RTE_GRAPH_FEATURE_REGISTER().

       Definition at line 275 of file rte_graph_feature_arc.h.

   const char* runs_after
       Feature ordering constraints runs_after: Name of the feature after which "this feature" should run

       Definition at line 280 of file rte_graph_feature_arc.h.

   const char* runs_before
       Feature ordering constraints runs_before: Name of the feature which must run after "this feature"

       Definition at line 285 of file rte_graph_feature_arc.h.

   rte_graph_feature_override_index_cb_t override_index_cb
       Allow each feature registration to override arc->max_indexes

       If set, struct rte_graph_feature_arc_register::max_indexes is calculated as follows (before calling
       rte_graph_feature_arc_create())

       FOR_EACH_FEATURE_REGISTER(arc, feat) { rte_graph_feature_arc_register::max_indexes =
       max(feat->override_index_cb(), rte_graph_feature_arc_register::max_indexes) }

       Definition at line 298 of file rte_graph_feature_arc.h.

   rte_graph_feature_change_notifier_cb_t notifier_cb
       Callback for notifying any change in feature enable/disable state

       Definition at line 303 of file rte_graph_feature_arc.h.
