📦 version 7.3.1, in nixpkgs unstable

💅 idpf_vport_i...st_path_txqs(9) — the Kernel API Manual page, bestie edition 🎀

okay so this page lives in the Kernel API Manual, and the title up top is idpf_vport_i...st_path_txqs(9) (yes the name is literally truncated with dots in the header, that's not me being lazy, that's just how it ships 💀). Anyway. Sit down, hydrate, let's talk txq arrays.

✨ NAME ✨

idpf_vport_init_fast_path_txqs — Initialize fast path txq array 🦋

🌸 SYNOPSIS 🌸

int idpf_vport_init_fast_path_txqs (struct idpf_vport *vport , struct
       idpf_q_vec_rsrc *rsrc );

Like, that's the whole signature. She returns an int, she takes two pointers, she's booked and busy. 👑

🫶 ARGUMENTS 🫶

  • vport — the vport we're init-ing txqs on. literally the main character of this function ngl.
  • rsrc — a pointer to the queue and vector resources. the supporting cast. 🎀

💖 DESCRIPTION 💖

okay so the vibe here is: we get a queue index from skb->queue_mapping, right? and then we need a fast way to dereference the queue from queue groups. like, fast fast. no cap.

that's what this does — it lets us quickly pull a txq based on a queue index. that's the entire personality. lowkey iconic that a lookup table gets its own manpage. 💅

⭐ RETURN ⭐

0 on success, negative on failure. so like, if you get a negative number, that's your sign to go touch grass and go fix something. 😭

🔥 SEE ALSO 🔥

the kernel file lives at ./drivers/net/ethernet/intel/idpf/idpf_txrx.c — go read her, she's long but she ate.

and here's the whole squad, fr fr, nobody left behind:

lowkey no warnings, no bugs, no copyright drama on this one — she's a clean page. the only caveat is the return value: check it. negative means something went sideways and you will be debugging at 2am. 🫶

and that's the page!! 🧚 source path is ./drivers/net/ethernet/intel/idpf and this cutie is dated October 2026 — go forth, initialize those fast path txqs, and remember: check your return value, bestie. 💜💅✨
