💖 rte_eth_rxq_info 💖

okay bestie, gather round, because today we're getting to know rte_eth_rxq_info — a lil' struct from the DPDK library gang (it lives in the Library Functions Manual, iykyk) whose entire job is telling you what's up with an Ethernet device's Rx queue. No cap. 🎀

✨ NAME ✨

rte_eth_rxq_info — the Rx queue info structure, and yes she's the main character 💅

🌸 SYNOPSIS 🌸

#include <rte_ethdev.h>

🦋 Data Fields 🦋

  • struct rte_mempool * mp
  • struct rte_eth_rxconf conf
  • uint8_t scattered_rx
  • uint8_t queue_state
  • uint16_t nb_desc
  • uint16_t rx_buf_size
  • uint8_t avail_thresh

💜 Detailed Description 💜

It's giving… Ethernet device Rx queue information structure. That's literally her whole thing. You use her to retrieve info about a queue that's already been configured. She's not here to set anything up, she's here to report, and honestly? Respect. 👑

🎀 Field Documentation 🎀

🌈 struct rte_mempool* mp

the mempool that this queue is using, fr fr.

Definition at line 1895 of file rte_ethdev.h.

🌈 struct rte_eth_rxconf conf

the queue's config parameters. all the settings, all the vibes. ✨

Definition at line 1896 of file rte_ethdev.h.

🌈 uint8_t scattered_rx

whether scattered packet Rx is supported. if packets are out here living their fragmented truth, this is the field that tells you. 🧚

Definition at line 1897 of file rte_ethdev.h.

🌈 uint8_t queue_state

one of the RTE_ETH_QUEUE_STATE_* values. that's it, that's the whole description, she's mysterious like that 💀

Definition at line 1898 of file rte_ethdev.h.

🌈 uint16_t nb_desc

the configured number of RXDs. RXD count, locked in. 🔥

Definition at line 1899 of file rte_ethdev.h.

🌈 uint16_t rx_buf_size

the hardware receive buffer size. hardware-level, no middleman. 💪

Definition at line 1900 of file rte_ethdev.h.

🌈 uint8_t avail_thresh

okay this one has LORE bestie, listen up 🫶

Available Rx descriptors threshold, defined as a percentage of the Rx queue size. If the number of available descriptors drops lower than that, the event RTE_ETH_EVENT_RX_AVAIL_THESH gets generated — so it's basically a lil' bat signal for "hey, we're running low on descriptors over here."

and a value of 0 means the threshold monitoring is disabled. zero, off, nothing, nada. don't come crying when no event fires, because you turned it off yourself. 😭
