i40e_ptp_set_pins(9)

i40e_ptp_set_pins(9) 💅 — the Kernel API Manual, bestie edition

okay so you opened the i40e_ptp_set_pins(9) page from the Kernel API Manual and honestly? iconic choice. this is the little function that actually shoves your PTP pin settings into the hardware for a specific PF. let's get into it ✨

---

🌸 NAME 🌸

i40e_ptp_set_pins — set PTP pins in HW. that's it, that's the whole vibe 💖

---

🦋 SYNOPSIS 🦋

int i40e_ptp_set_pins (struct i40e_pf *pf , struct
       i40e_ptp_pins_settings *pins );

like, literally just two structs in and an int out. slay 🎀

---

✨ ARGUMENTS ✨

• pf — the board private structure. your main character struct 👑
• pins — the PTP pins that are gonna get applied. the whole point, fr fr 🎯

---

💜 DESCRIPTION 💜

so what it does is: validate and set PTP pins in HW for a specific PF. that's the job, no cap.

return 0 on success 🎉 or a negative value on error 😭 — so bestie, please actually check the return value, i'm begging.

ngl the negative-number-on-error thing is real: 0 means good, anything negative means something went sideways 🙈
