ice_ptp_init_tx(9)

💖 ice_ptp_init_tx — like, the Kernel API Manual, but make it make sense 💖

okay bestie, welcome to the ice_ptp_init_tx(9) glow-up ✨ this is a page from the Kernel API Manual, and honestly? it's short, it's sweet, and it's about to be your new hyperfixation 🎀

---

🌸 NAME 🌸

ice_ptp_init_tx — literally just initializing the tracking for Tx timestamps 💅 that's the whole vibe, no cap.

---

✨ SYNOPSIS ✨

int ice_ptp_init_tx (struct ice_pf *pf , struct ice_ptp_tx *tx , u8 port );

she takes three things and gives you back an int, periodt 🫶

---

🦋 ARGUMENTS 🦋

• pf — the board private structure, aka the main character of this whole operation 👑
• tx — the Tx tracking structure you're gonna initialize (yes, this exact one, don't get it twisted 🙈)
• port — the port that this structure is tracking 🌈

---

💜 DESCRIPTION 💜

so the way this works is: ice_ptp_init_tx initializes the Tx timestamp tracker for this PF. that's it, that's the job ✨

and here's the tea 🍓 — for all PHYs except E82X, every single port has its own block of timestamps, independent of all the other ports. like, no sharing, no overlap, each port living its own best life 💅 E82X? not invited to that party, she's built different, iykyk 😭

---

⭐ RETURN ⭐

• 0 on success — slay, we ate, no notes 💖
• -ENOMEM when you're out of memory — aka the vibe check failed, sorry bestie 💀
