🌸 SYNOPSIS 🌸

int e1000e_phc_adjfine (struct ptp_clock_info *ptp , long delta );

---

🎀 ARGUMENTS 🎀

• ptp — the ptp clock structure, aka the clock’s main-character data structure 💅
• delta — Desired frequency chance in scaled parts per million. yes, “chance” is literally what the page says, I’m just relaying it bestie 😭 no cap.
