💖 ksz_wol_pre_shutdown(9) 💖

okay so bestie, welcome to the Kernel API Manual ✨ this one's a little function with a big job, and honestly? she ate. let's get into it 🫶

---

🌸 NAME 🌸

ksz_wol_pre_shutdown — she gets the switch device all cozy and ready for shutdown, while being a total overachiever and also taking Wake-on-LAN (WoL) settings into account 💅

---

✨ SYNOPSIS ✨

void ksz_wol_pre_shutdown (struct ksz_device *dev );

like, that's the whole vibe. no return value, no drama, just vibes and a pointer 🌈

---

🎀 ARGUMENTS 🎀

• dev — the switch device structure. yeah, that's the one. the main character of this whole operation 👑

---

🦋 DESCRIPTION 🦋

so here's the tea ☕ — this function preps the switch device for a safe shutdown, and while she's doing that she's also keeping an eye on the Wake-on-LAN (WoL) settings on the user ports. like, simultaneously. multitasking icon behavior, no cap 🔥

it's giving "responsible older sister who remembers to turn off the stove and check that the wifi is still on so you can wake the machine back up later" 😭💖
