igb_reset_q_vector(9)

💅 igb_reset_q_vector — the kernel API manual, but make it make sense

okay so bestie, we're in the igb (Intel gigabit ethernet) driver corner of the kernel, and this little function is literally just here to tidy up one single interrupt vector before it gets yeeted. no cap. 🌸

---

✨ NAME ✨

igb_reset_q_vector — Reset config for interrupt vector 🎀

like, it resets the config for an interrupt vector. that's the whole vibe check. 💫

---

🦋 SYNOPSIS 🦋

void igb_reset_q_vector (struct igb_adapter *adapter , int v_idx );

so it returns nothing (void), takes your board's private struct, and takes an int index. slay. 💅

---

🌸 ARGUMENTS 🌸

• adapter — the board private structure to initialize. it's giving "the whole driver's personal diary" energy 💜
• v_idx — the index of the vector you want reset. yes, you have to tell it which one. no guessing games 🎯

---

🔥 DESCRIPTION 🔥

okay so here's the tea ☕: if NAPI is enabled, this function deletes any references to the NAPI struct. that's it, that's the whole job. 🧹✨

and why? because it's literally preparation for igb_free_q_vector — think of it as the pre-game before the actual cleanup. you reset the config first so the freeing later doesn't trip over stale references. main character prep energy fr fr. 👑

ngl, if you're reading a manpage about interrupt vector reset, you're already kind of iconic. 🔥
