phylink_mac_change(9)

💅 phylink_mac_change 💅

okay bestie, welcome to the Kernel API Manual page for phylink_mac_change — she's a tiny little notifier function and she ate, no cap ✨

---

🌸 NAME 🌸

phylink_mac_change — like, notify phylink that your MAC state changed 💖

---

🦋 SYNOPSIS 🦋

void phylink_mac_change (struct phylink *pl , bool up );

---

🎀 ARGUMENTS 🎀

• pl — a pointer to a struct phylink returned from phylink_create. yes, that struct phylink, the one you got back earlier, don't lose her 🫶
• up — a bool that says whether the link is currently up. that's it, up or not up, main character energy only 😌

---

✨ DESCRIPTION ✨

okay so here's the vibe: the MAC driver should call this function whenever the state of its link changes.

like — link failure, new negotiation results, etc. etc. 💅 all of it. the moment something shifts, you let phylink know. it's giving "keep your bestie in the loop" fr fr 🔥
