ixgbe_free_q_vectors(9)

💅 ixgbe_free_q_vectors — bestie edition ✨

okay so real talk, this is the ixgbe_free_q_vectors page from the Kernel API Manual, and it's literally the cleanup crew of the ixgbe world 🧹💖 she's here to free stuff, and she's gonna do it correctly.

---

🌸 NAME 🌸

ixgbe_free_q_vectors — frees the memory that got allocated for interrupt vectors, no cap 🫶

---

✨ SYNOPSIS ✨

void ixgbe_free_q_vectors (struct ixgbe_adapter *adapter );

that's it, that's the whole vibe. returns void, so like… she doesn't report back, she just does it 💅

---

🎀 ARGUMENTS 🎀

• adapter — the board private structure to initialize. yes bestie, she needs the board's private struct, that's her whole world 🌈

---

🦋 DESCRIPTION 🦋

so what she does is: this function frees the memory that was allocated to the q_vectors. simple. iconic. 💖

and in addition (the way that it's not just a free, it's a whole cleanup moment ✨), if NAPI is enabled, it will delete any references to the NAPI struct prior to freeing the q_vector. like, references first, then the free — order matters, don't come for her 🙈

lowkey important: ixgbe_alloc_q_vectors(9) is the one that sets all this up, so if you're ever confused about what got allocated in the first place, that's your girl 👑

okay that's the page!! mwah 💋 this dropped from ./drivers/net/ethernet/intel/i... (yeah the path got cut off in the original, blame the terminal bestie 😭) dated October 2026, all about ixgbe_free_q_vectors(9) — go free those vectors, slay, periodt 🌟🍓🧚‍♀️
