rte_eth_fc_conf(3)

📦 version 26.03, in nixos 26.05, nixpkgs unstable

💅 rte_eth_fc_conf 💅

okay bestie, so this one is from the Library Functions Manual — it's rte_eth_fc_conf, and she's a struct, not a function (I know, the name is giving function but she is NOT, so don't come for me 🫶). Buckle up, we're configuring Ethernet flow control and it's lowkey iconic.

✨ NAME ✨

rte_eth_fc_conf — the struct that holds all your Ethernet flow control parameters 🌸

🦋 SYNOPSIS 🦋

#include <rte_ethdev.h>

🎀 Data Fields 🎀

  • uint32_t high_water
  • uint32_t low_water
  • uint16_t pause_time
  • uint16_t send_xon
  • enum rte_eth_fc_mode mode
  • uint8_t mac_ctrl_frame_fwd
  • uint8_t autoneg

💖 Detailed Description 💖

So this is a structure used to configure Ethernet flow control parameter — like, that's literally her whole job, no cap. These parameters get configured straight into the register of the NIC, so it's not vibes-only, it's real hardware, periodt.

⚠️ heads up bestie: please refer to the corresponding data sheet for proper value. Do NOT just make numbers up, I'm begging you 😭 the data sheet is your bestie here.

She's defined at line 1408 of file rte_ethdev.h — iykyk.

🌈 Field Documentation 🌈

🌸 uint32_t high_water

The high threshold value that triggers XOFF 🔥

Defined at line 1409 of file rte_ethdev.h.

🌸 uint32_t low_water

The low threshold value that triggers XON ✨

Defined at line 1410 of file rte_ethdev.h.

🌸 uint16_t pause_time

The pause quota that goes inside the Pause frame 🎀

Defined at line 1411 of file rte_ethdev.h.

🌸 uint16_t send_xon

Asks the question: is XON frame need be sent? 👀 (yes, that's the original phrasing, I'm not fixing her, she's perfect)

Defined at line 1412 of file rte_ethdev.h.

🌸 enum rte_eth_fc_mode mode

The link flow control mode 👑

Defined at line 1413 of file rte_ethdev.h.

🌸 uint8_t mac_ctrl_frame_fwd

Forward MAC control frames — yep, that's the whole thing 🦋

Defined at line 1414 of file rte_ethdev.h.

🌸 uint8_t autoneg

Use Pause autoneg, because sometimes you just let the link negotiate for itself, main character energy 💅

Defined at line 1415 of file rte_ethdev.h.
