💅 t4vf_free_vi — free a virtual interface (kernel API manual, bestie edition)

okay so this is t4vf_free_vi(9) from the Kernel API Manual — yes, we're doing kernel manpage study time, and honestly? it's giving main character energy. stay with me 🫶

✨ NAME ✨

t4vf_free_vi — free a virtual interface. that's the whole vibe. releasing a VI back into the wild 🌈

---

🎀 SYNOPSIS 🎀

int t4vf_free_vi (struct adapter *adapter , int viid );

like, you hand it an adapter and a viid and it returns an int. no cap, that's it 💅

---

🦋 ARGUMENTS 🦋

• adapter — the adapter, bestie. the whole point. the main character of this function call ✨
• viid — the virtual interface identifier. basically the VI's name tag at the function party 🎀

---

🌸 DESCRIPTION 🌸

so what does it do? it frees a previously allocated Virtual Interface. like, you allocated a VI earlier (iconic of you), and now you're done with it, so this function takes it back. cleanup era 🧹✨

and if it fails? it returns an error. not "maybe", not "we'll see" — it literally returns an error on failure. so check your return value, bestie, fr fr 😭
