📦 version 7.3.1, in nixpkgs unstable

💅 idpf_ptp_request_ts — the Kernel API Manual, bestie edition 🎀

okay so this is idpf_ptp_request_ts(9) from the Kernel API Manual, and it's literally the girl whose whole job is grabbing you a Tx timestamp slot before you yeet your packet out the door ✨ no cap, she's the plug for timestamp indexes.

🌸 NAME 🌸

idpf_ptp_request_ts — request an available Tx timestamp index 🫶

⭐ SYNOPSIS ⭐

int idpf_ptp_request_ts (struct idpf_tx_queue *tx_q , struct sk_buff
*skb , u32 *idx );

like… she takes three things and hands you back an int, periodt 💅

🦋 ARGUMENTS 🦋

  • tx_q — the transmit queue where you're asking for this Tx timestamp. that's the vibes location, bestie 🎀
  • skb — the SKB you're tying to this timestamp request. your packet, your problem, your main character energy 💖
  • idx — index of the Tx timestamp latch. this is the little number that comes back out 🔥

🌈 DESCRIPTION 🌈

so what she actually does: she requests the Tx timestamp index that got negotiated during PTP init, and that index is the one that's gonna be set into the Tx descriptor. iykyk 👑

like, that's it. that's the whole job. she gets you the index, you put it in the descriptor, everybody slays ✨

👑 RETURN 👑

on success she gives you 0 and the index — the very same index you can hand straight to the Tx descriptor 🎀 otherwise you get -errno. it's giving "no notes, just vibes" when it works and "we don't talk about it" when it doesn't 😭

and now the whole friend group, alphabetically-ish, all of them, because we don't leave a single bestie out of the group chat:

that's the whole page, bestie, and yes she ate 💅 this one came from ./drivers/net/ethernet/intel/idpf, dated October 2026, and the manual it lives in is the Kernel API Manual — so go forth, request those timestamps, and slay 🔥✨🎀
