💅 fbnic_mac_request_irq(9) — like, the whole glow-up

okay so bestie, welcome to the Kernel API Manual ✨ this one's from the fbnic corner of the kernel and it's honestly so chill. buckle up 🎀

---

🌸 NAME 🌸

fbnic_mac_request_irq — the function that sets up the MAC so it can, y'know, actually advertise link 🦋

---

✨ SYNOPSIS ✨

int fbnic_mac_request_irq (struct fbnic_dev *fbd );

like yes that's the whole signature, she's short and sweet 💖

---

🫶 ARGUMENTS 🫶

• fbd — pointer to the device you're initializing. that's it, that's the arg, she's the main character 👑

---

💅 DESCRIPTION 💅

so this function does the basic bringup for the MAC/PHY IRQ. like, the starter-pack setup, the "get her ready" moment 🌈

but here's the tea: for now the IRQ will remain disabled until we actually start the MAC/PCS/PHY logic via phylink. so she's requested, she's configured, but she is not firing yet — she's waiting for her cue 🎭 no cap.

---

🔥 RETURN 🔥

• non-zero on failure 💀 — so if you get zero back, congrats, slay. if not… bestie, something went sideways.
