💅 fbnic_mac_free_irq(9) ✨

okay so bestie, welcome to the Kernel API Manual — this is the fbnic_mac_free_irq page and it's literally the cleanup era of the MAC IRQ saga 🧹💖

---

🌸 NAME 🌸

fbnic_mac_free_irq — teardown the MAC IRQ so the device can be stopped 🛑 like it's giving "pack your bags, we're closing" energy

---

⭐ SYNOPSIS ⭐

void fbnic_mac_free_irq (struct fbnic_dev *fbd );

no return value, bestie — it just does the thing and dips 🫶

---

🎀 ARGUMENTS 🎀

• fbd — pointer to the device that is stopping 👋 like, the actual struct fbnic_dev * that's on its way out

---

🦋 DESCRIPTION 🦋

so this function undoes all the work that fbnic_mac_request_irq did earlier 😭 it's the reverse uno card of IRQ setup, fr fr.

it also gets the device prepped to no longer receive traffic on the host interface — so think of it as the moment your fave goes offline. iconic, but also kind of sad 💀✨
