💖 rte_table_..._lb_config(3) 💖

okay bestie, welcome to the Library Functions Manual entry for rte_table_..._lb_config(3) — yes the title has dots in it, that's just how Doxygen does, we don't question it, we respect it 💅

✨ NAME ✨

rte_table_action_lb_config — the load-ballance action config struct, and yes we're pronouncing it like that now 🎀

🌸 SYNOPSIS 🌸

#include <rte_table_action.h>

🦋 Data Fields 🦋

  • uint32_t key_size
  • uint32_t key_offset
  • uint8_t key_mask[RTE_TABLE_ACTION_LB_KEY_SIZE_MAX]
  • rte_table_hash_op_hash f_hash
  • uint64_t seed
  • uint32_t out_offset

💜 Detailed Description 💜

so this is the load balance action configuration — and it's per table action profile, meaning every action profile gets its own lil copy, no sharing, main character energy only 👑

🔥 Field Documentation 🔥

💫 uint32_t key_size

key size, bestie — as in the number of bytes, that's the unit, don't come at me with bits 🍓

Definition at line 148 of file rte_table_action.h.

💫 uint32_t key_offset

where the key starts, as an offset within the input packet buffer. And listen — offset 0 points to the first byte of the MBUF structure, not the packet payload, not the headers, the MBUF itself. write that down. tattoo it. 📝

Definition at line 153 of file rte_table_action.h.

💫 uint8_t key_mask[RTE_TABLE_ACTION_LB_KEY_SIZE_MAX]

the key mask, queen 👑 and the important bit: only key_size bytes are valid. the rest of that array is just vibes, do not read it, do not trust it, look away 🙈

Definition at line 156 of file rte_table_action.h.

💫 rte_table_hash_op_hash f_hash

your hash function. literally just the function pointer, that's the whole tea ☕

Definition at line 159 of file rte_table_action.h.

💫 uint64_t seed

the seed value for f_hash. feed it to your hash function and let it cook 🔥

Definition at line 162 of file rte_table_action.h.

💫 uint32_t out_offset

where the output value goes — an offset within the input packet buffer. Same rules as before, no cap: offset 0 points to the first byte of the MBUF structure. it's giving symmetry, it's giving consistency 🌈
