💅 ice_ptp_mark_tx_tracker_stale — Kernel API Manual, section 9

okay so bestie, welcome to the ice_ptp_mark_tx_tracker_stale(9) page 💖 this is the glow-up of a classic Kernel API Manual entry, and we're gonna get you fluent in it in like two minutes, no cap.

---

✨ NAME ✨

ice_ptp_mark_tx_tracker_stale — literally the function that marks unfinished timestamps as stale 🎀

---

🦋 SYNOPSIS 🦋

void ice_ptp_mark_tx_tracker_stale (struct ice_ptp_tx *tx );

like, that's it. that's the whole signature. she's short and she knows it 💅

---

🌸 ARGUMENTS 🌸

• tx — the tracker to mark 🫶 (yes bestie, this is the one you're marking, keep up)

---

👑 DESCRIPTION 👑

so here's the tea ☕ — this function marks all the currently outstanding Tx timestamps as stale. think of it as putting a little "expired" sticker on them 🏷️

why do we care? because marking them stale is what prevents their timestamp value from being sent up to the stack. and that matters because — and this is the important part, bestie — it's required to prevent extending the 40bit hardware timestamp incorrectly 😭 like if you don't do this, the 40bit hardware timestamp gets extended wrong, and that's a bad time.

when should you call her? whenever the PTP clock is modified — for example, after a set time request ✨ she's your little cleanup queen for that exact moment, iykyk.

no skipping this step, fr fr. it's not a vibe, it's a requirement 🙈
