igc_free_q_vector(9)

💅 igc_free_q_vector(9) — a Kernel API Manual moment

okay so bestie, welcome to the Kernel API Manual, the igc_free_q_vector(9) page specifically, and honestly? it's a little one but it's iconic 🎀

---

🌸 NAME 🌸

igc_free_q_vector — literally just frees the memory allocated for a specific interrupt vector. that's the whole gig. slay 💅

---

✨ SYNOPSIS ✨

void igc_free_q_vector (struct igc_adapter *adapter , int v_idx );

no cap, that's the entire signature. two args, no return, in and out 🫶

---

🦋 ARGUMENTS 🦋

• adapter — the board private structure to initialize. that's your context bestie, the whole board's little private world 🌸
• v_idx — the index of the vector you want freed. pick your vector, free your vector 💖

---

💀 DESCRIPTION 💀

so what does it actually do? this function frees the memory allocated to the q_vector. that's it. that's the function. it's giving "cleanup era" and we respect it 🙈

like any free, it's a one-way vibe — once it's freed, it's freed, so don't come knocking on that q_vector afterwards, iykyk.
