rte_eth_pfc_queue_conf(3)

📦 version 26.03, in nixos 26.05, nixpkgs unstable

💖 NAME 💖

rte_eth_pfc_queue_conf — ok bestie, this is the rte_eth_pfc_queue_conf(3) page from the Library Functions Manual, and it's literally the struct you use to set up Ethernet priority flow control params for ethdev queues 🎀

✨ SYNOPSIS ✨

#include <rte_ethdev.h>

🫶 Data Fields

  • enum rte_eth_fc_mode mode

🌸 DETAILED DESCRIPTION 🌸

⚠️ Warning, fr fr: EXPERIMENTAL — this API may change, or be removed, without prior notice. No cap, don't build your whole personality on it staying the same 😭

So. A structure used to configure Ethernet priority flow control parameters for ethdev queues. That's the whole vibe 💅

rte_eth_pfc_queue_conf::rx_pause structure shall be used to configure given tx_qid with corresponding tc. When the ethdev device receives a PFC frame with rte_eth_pfc_queue_conf::rx_pause::tc, traffic will be paused on rte_eth_pfc_queue_conf::rx_pause::tx_qid for that tc 🦋

rte_eth_pfc_queue_conf::tx_pause structure shall be used to configure given rx_qid. When rx_qid is congested, PFC frames are generated with rte_eth_pfc_queue_conf::rx_pause::tc and rte_eth_pfc_queue_conf::rx_pause::pause_time to the peer ✨

DPDK — Version 26.03.0 🌸 that's the source and version bestie, and the date on the original footer line is just the rte_eth_pfc_queue_conf(3) manual tag itself, so consider it signed, sealed, slayed 🫶✨
