💖 NAME 💖

rte_port_in_action_lb_config — it's giving load-balance-action-config energy, bestie 💅 she lives in rte_port_in_action.h and she's the per action profile config girlie, no cap.

Also hi, welcome to the rte_port_i..._lb_config(3) page 🎀 — that's the manual name, in case you were wondering why your man invocation was so mysterious about it.

✨ SYNOPSIS ✨

#include <rte_port_in_action.h>

🦋 Data Fields 🦋

Okay so she's a struct and these are her fields, in order, exactly like this:

  • uint32_t key_size
  • uint32_t key_offset
  • uint8_t key_mask [RTE_PORT_IN_ACTION_LB_KEY_SIZE_MAX]
  • rte_table_hash_op_hash f_hash
  • uint64_t seed
  • uint32_t port_id [RTE_PORT_IN_ACTION_LB_TABLE_SIZE]

🌸 DETAILED DESCRIPTION 🌸

Load balance action configuration (per action profile). That's it, that's the whole vibe — she holds the settings that describe how one load-balance action profile does its thing. 👑

💜 FIELD DOCUMENTATION 💜

⭐ uint32_t key_size

Key size, measured in number of bytes. Literally just how many bytes of key you're working with. 📏

Defined at line 124 of file rte_port_in_action.h.

⭐ uint32_t key_offset

Key offset within the input packet buffer. Heads up bestie, offset 0 points to the first byte of the MBUF structure — not the packet payload, the mbuf itself. Lowkey important, don't skip it. 🙈

Defined at line 129 of file rte_port_in_action.h.

⭐ uint8_t key_mask[RTE_PORT_IN_ACTION_LB_KEY_SIZE_MAX]

Key mask. Only key_size bytes are valid, so don't get cute with the rest of the array. 💅

Defined at line 132 of file rte_port_in_action.h.

⭐ rte_table_hash_op_hash f_hash

Hash function. She's the girl doing the hashing. 🔥

Defined at line 135 of file rte_port_in_action.h.

⭐ uint64_t seed

Seed value for f_hash. Feed her the seed, she makes the hashes. 🌱

Defined at line 138 of file rte_port_in_action.h.

⭐ uint32_t port_id[RTE_PORT_IN_ACTION_LB_TABLE_SIZE]

Table defining the weight of each pipeline output port. Okay so the weights here are set in 1/RTE_PORT_IN_ACTION_LB_TABLE_SIZE increments — that's the unit, that's the whole scale. 🎚️

The way this works: to assign a weight of N/RTE_PORT_IN_ACTION_LB_TABLE_SIZE to a given output port, where 0 <= N <= RTE_PORT_IN_ACTION_LB_TABLE_SIZE, the output port needs to show up exactly N times in this table. Exactly. Count her appearances, that's her weight. 🧮

Can be updated later. So she's not locked in forever, she's flexible, we love that for her. 💫

Okay bestie that's the whole page, mwah 😭💖 — this was DPDK, Version 25.11.3, and yeah the footer girlie says rte_port_i..._lb_config(3) too, so now you know both halves of the title. Periodt. 🌈👑
