✨ t4vf_identify_port(9) ✨

okay so this is a page from the Kernel API Manual and honestly bestie, it's a lil cutie 💖 — it's all about making a network port physically glow so you can find it. main character energy fr.

🌸 NAME 🌸

t4vf_identify_port — identify a VI's port by blinking its LED 💡✨

---

🎀 SYNOPSIS 🎀

int t4vf_identify_port (struct adapter *adapter , unsigned int viid ,
       unsigned int nblinks );

---

🦋 ARGUMENTS 🦋

• adapter — the adapter, like, the whole card you're working with 🫶
• viid — the Virtual Interface ID, iykyk 👑
• nblinks — how many times to blink the LED at 2.5 Hz. yes, an actual blink count, not a vibe 💅

---

⭐ DESCRIPTION ⭐

Identifies a VI's port by blinking its LED. that's it, that's the whole thing — but honestly? iconic. you point at the rack, the light goes blink blink, and you found your port. slay 🌈

No cap, this is the whole function: it makes the LED do the thing so you can spot which physical port belongs to your VI. lowkey the most satisfying syscall-adjacent behaviour in existence 😭
