🦋 DETAILED DESCRIPTION 🦋

Okay so this is the Feature registration structure that you hand over to RTE_GRAPH_FEATURE_REGISTER(). That's the whole vibe. She's the little form you fill out so your feature gets properly introduced to the arc. 💅

👑 MEMBER FUNCTION DOCUMENTATION 👑

STAILQ_ENTRY (rte_graph_feature_register)

Pointer to next registered feature in the same arc. It's giving linked list, it's giving "who's next bestie" 🌈

---

💜 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. Short, sweet, self-explanatory. 🎀

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 you're registering the feature via RTE_GRAPH_FEATURE_REGISTER() — she'll handle it, no cap.

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.

Heads up: if the application calls rte_graph_feature_arc_init(), then the node->process() you provided in RTE_NODE_REGISTER() gets overwritten by this function. Not a drill, that's literally the behavior. 😭

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. Ma'am, you're up after them. 💅

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". So like… you go first, periodt. 👑

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. She will let you know the moment something flips. 🔔

Okay bestie, that's a wrap! This page came to you from the DPDK crew, Version 25.11.3, and it lives under the manual as rte_graph_...e_register(3) — a member of the Library Functions Manual family. Now go register that feature, slay, and stay hydrated. 💖✨🧚
