ksz_handle_wake_reason(9)

💖 ksz_handle_wake_reason(9) — Kernel API Manual 💖

🌸 NAME 🌸

ksz_handle_wake_reason — literally handles the wake reason on a specified port, bestie. 💅

✨ SYNOPSIS ✨

int ksz_handle_wake_reason (struct ksz_device *dev , int port );

🧚 ARGUMENTS 🧚

• dev — the device structure, obvi.
• port — the port number, periodt.

🦋 DESCRIPTION 🦋

okay so picture this: ksz_handle_wake_reason reads the PME (Power Management Event) status register of the port you picked, all to figure out the wake reason. If there’s no wake event, it returns early and dips out. If there is one, it logs the wake reason — which could be due to a "Magic Packet", a "Link Up", or an "Energy Detect" event. Then the PME status register gets cleared to acknowledge that the wake event has been handled. iconic behavior, ngl. 😭

🔥 RETURN 🔥

0 on success, or an error code on failure. that’s the whole return vibe, no cap. 💀
