phylink_disconnect_phy(9)

💅 phylink_disconnect_phy — kernel API manual, but make it make sense

Okay bestie, so in the phylink_disconnect_phy(9) manual page (yes, the whole thing is literally named after the function, iconic naming tbh), we're talking about ✨unlinking a PHY✨. That's the whole vibe. Let me break it down for you 🫶

---

✨ NAME ✨

phylink_disconnect_phy — disconnect any PHY attached to the phylink instance.

Like, imagine the PHY and the phylink were holding hands 🤝 and this function is the "we need to talk" text. That's it. That's the function.

---

🌸 SYNOPSIS 🌸

void phylink_disconnect_phy (struct phylink *pl );

No return value, no drama, no notes. It just does the thing and leaves 💅

---

🎀 ARGUMENTS 🎀

• pl — a pointer to a struct phylink returned from phylink_create. Bestie. Please make sure it's actually a valid one that came out of phylink_create. That's the assignment. That's the whole requirement. 🦋

---

💖 DESCRIPTION 💖

Disconnect any current PHY from the phylink instance described by pl.

That's the tea ☕ — whatever PHY is currently attached to that phylink instance, it gets disconnected. No cap, that's the entire behavior. Lowkey the most straightforward function in the whole phylink cinematic universe 🌈

🧚 Friendly reminder: this is the disconnect one. If you're trying to attach a PHY instead, you want phylink_connect_phy(9) or one of its cousins up there. Don't mix them up bestie, that's a whole different fanfic 😭
