i40e_alloc_arq_bufs(9)

📦 version 7.3.1, in nixpkgs unstable

💖 NAME 💖

i40e_alloc_arq_bufs — the glow-up where we allocate all those pre-posted buffers for the receive queue ✨ (that's the ARQ bestie, she's the one receiving things, iykyk)

🌸 SYNOPSIS 🌸

int i40e_alloc_arq_bufs (struct i40e_hw *hw );

So like, one function, returns an int, takes one pointer. Simple queen behavior, no cap. 🎀

🦋 ARGUMENTS 🦋

  • hw — pointer to the hardware structure 💅 like, the actual hardware struct, she's giving main character energy, everything else is just vibing off her

👑 SEE ALSO 👑

Okay bestie, buckle up, because this is the friend group and they're all iconic in their own way 🫶

The source file, aka where she lives:

  • Kernel file ./drivers/net/ethernet/intel/i40e/i40e_adminq.c — literally her home address, go say hi 🌈

The adminq ring allocation/free squad:

The buffer besties (allocate and free, they come as a set fr fr):

The register configuration girlies:

The init girlies (setting things up ✨):

The shutdown girlies (saying bye, but make it graceful):

The caps + adminq lifecycle girlies:

The cleanup/status queens:

The send-command atomic trio (yes there's three of them, don't ask, just accept 💀):

And the last two icons:

Like, that's the whole roster. Every single one of them. Don't skip anybody, they all get along and tbh the ARQ buffers would not be allocated without them 🧚

Okay that's the whole page bestie, no notes, you ate 💅

Sign-off szn: this one lives at ./drivers/net/ethernet/intel/i40e, stamped October 2026, and yes it's the same i40e_alloc_arq_bufs(9) you started with — full circle, slay ⭐🎀
