🎀 ksz8_w_phy_ctrl(9) — the MIIM PHY Control glow-up 💅

Okay bestie, so this is the manual page for ksz8_w_phy_ctrl(9) and it's literally about translating and writing to the SMI interface from a MIIM PHY Control register (Reg. 31). No cap, it's giving "I speak both languages" energy. ✨

🌸 NAME 🌸

ksz8_w_phy_ctrl — translates and writes to the SMI interface from a MIIM PHY Control register (Reg. 31). 🦋

---

✨ SYNOPSIS ✨

int ksz8_w_phy_ctrl (struct ksz_device *dev , int port , u16 val );

---

💖 ARGUMENTS 💖

• dev — the KSZ device instance. Like, the main character object you're working with. 👑
• port — the port number to be configured. Which port are we serving looks today? 💅
• val — the register value to be written. The actual data going in. 🎀

---

🔥 DESCRIPTION 🔥

This function translates control settings from a MIIM PHY Control register into their corresponding hardware register bit values for the SMI interface. So basically it's a translator bestie — it takes the MIIM PHY Control vibes and converts them into the exact bit values the SMI hardware expects. The way that it bridges two register worlds? Obsessed. 🧚✨

🌈 RETURN 🌈

• 0 on success — slay, it worked. ✅
• error code on failure — not slay, something went wrong. 😭
