RTE_ETH_RECYCLE_RXQ_INFO(3)

💖 rte_eth_recycle_rxq_info 💖

okay bestie, welcome to the lil struct that does the mbuf recycling thing ✨ it's a 3 manpage, from the Library Functions Manual, and it's literally just... a vibe. a whole struct. let's get into it 🫶

✨ NAME ✨

rte_eth_recycle_rxq_info — the Ethernet Rx queue info struct for recycling mbufs, no cap 💅

---

🌸 SYNOPSIS 🌸

#include <rte_ethdev.h>

🎀 Data Fields

• struct rte_mbuf ** mbuf_ring
• struct rte_mempool * mp
• uint16_t * refill_head
• uint16_t * receive_tail
• uint16_t mbuf_ring_size
• uint16_t refill_requirement

---

🦋 Detailed Description 🦋

Warning ⚠️ EXPERIMENTAL: this structure may change without prior notice. so do NOT get attached, babe — it can shapeshift on you at any moment 😭

so basically this is the Ethernet device Rx queue information structure for recycling mbufs. iconic. You use it to retrieve Rx queue information when a Tx queue is reusing mbufs and moving them over into the Rx mbuf ring. like a lil relay race but for packets 🏃‍♀️💨

🔥 Field Documentation 🔥

👑 struct rte_mbuf** mbuf_ring

mbuf ring of Rx queue. the main character of the ring situation fr fr

Definition at line 1929 of file rte_ethdev.h.

👑 struct rte_mempool* mp

mempool of Rx queue. where the mbufs come from 🍼

Definition at line 1930 of file rte_ethdev.h.

👑 uint16_t* refill_head

head of Rx queue refilling mbufs.

Definition at line 1931 of file rte_ethdev.h.

👑 uint16_t* receive_tail

tail of Rx queue receiving pkts.

Definition at line 1932 of file rte_ethdev.h.

👑 uint16_t mbuf_ring_size

configured number of mbuf ring size. yes, the number of the size, it said what it said 💀

Definition at line 1933 of file rte_ethdev.h.

👑 uint16_t refill_requirement

Requirement on mbuf refilling batch size of Rx mbuf ring.

okay listen, this one's got ✨lore✨ — for some PMD drivers, the number of Rx mbuf ring refilling mbufs should be aligned with the mbuf ring size, so that ring wrapping around stays simple. Value 0 means that PMD drivers have no requirement for this — i.e. they're chill, no rules, go off 🕊️
