🦋 genphy_check_and_restart_aneg(9) 🦋

okay so bestie, welcome to the Kernel API Manual ✨ — yes that's the manual name, and yes this page lives there. Today's main character is genphy_check_and_restart_aneg, and honestly? she's the friend who checks if the group chat is still alive and restarts it if it's not. 💅

💖 NAME 💖

genphy_check_and_restart_aneg — Enable and restart auto-negotiation 🌸

---

✨ SYNOPSIS ✨

int genphy_check_and_restart_aneg (struct phy_device *phydev , bool
restart );

---

🎀 ARGUMENTS 🎀

• phydev — the target phy_device struct 👑 like, this is the PHY we're dealing with, no cap
• restart — bool that says whether an aneg restart is requested 🙈 so basically "girl, do we actually want to restart this or not"

---

🧚 DESCRIPTION 🧚

Check, and restart auto-negotiation if needed. 🫶

That's it, that's the whole vibe — she checks, and if the situation calls for it, she restarts auto-negotiation. Lowkey iconic, highkey useful. ⭐
