rte_table_..._lb_config(3)

💅 NAME 💅

rte_table_action_lb_config — okay bestie, this is the load balance action config struct, and it lives in the DPDK Library Functions Manual 🎀 (yes, the rte_table_..._lb_config(3) girlies, that's us).

✨ 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 🦋

Load balance action configuration — and it's per table action profile, so it's giving very much "configured once, slays everywhere" ✨.

Lowkey iconic detail: the whole thing is defined at line 146 of file rte_table_action.h. Noted, saved, screenshotted 📸.

💖 Field Documentation 💖

• uint32_t key_size — the key size, in bytes. That's it, that's the field. Defined at line 148 of rte_table_action.h 🫶
• uint32_t key_offset — where the key starts inside the input packet buffer. Heads up queen: offset 0 points to the first byte of the MBUF structure, not the packet data. Defined at line 153 of rte_table_action.h.
• uint8_t key_mask[RTE_TABLE_ACTION_LB_KEY_SIZE_MAX] — the key mask 🎭 and only the first key_size bytes are valid — the rest are just vibes. Defined at line 156 of rte_table_action.h.
• rte_table_hash_op_hash f_hash — the hash function. Your fave, your choice, your algorithm 💅 Defined at line 159 of rte_table_action.h.
• uint64_t seed — the seed value for f_hash 🌱 because every hash function needs a lil starting energy. Defined at line 162 of rte_table_action.h.
• uint32_t out_offset — where the output value lands inside the input packet buffer. Same rule as before bestie: offset 0 points to the first byte of the MBUF structure. Defined at line 167 of rte_table_action.h ⭐

Fr fr, respect the MBUF offset rule both times — key_offset and out_offset are counting from the top of the MBUF struct, not the payload. No cap. 💀

Okay that's the whole page bestie, mwah 💋 — this was the rte_table_..._lb_config(3) manpage from DPDK, Version 26.03.0, and we are DONE. Go configure something iconic. 🎀💜
