iavf_napi_poll(9)

💅 iavf_napi_poll — the Kernel API Manual, but make it group chat 🫶

okay so bestie, we're talking about iavf_napi_poll here — it's a kernel API manual page (section 9, iykyk) and it's literally the NAPI polling Rx/Tx cleanup routine. yes bestie, both directions. she does it all. 👑

---

✨ SYNOPSIS ✨

int iavf_napi_poll (struct napi_struct *napi , int budget );

that's the whole vibe right there. hand her a napi struct and a budget, she gives you back an int. iconic behavior honestly. 🎀

---

🌸 ARGUMENTS 🌸

• napi — the napi struct, and no cap, our device's info is living inside it. it's giving "everything you need is in this one bag" energy. 👜✨
• budget — how much work the driver is allowed to do this pass, measured in packets. think of it as her allowance for the round, and she is NOT overspending. 💸

---

💖 DESCRIPTION 💖

so this function will clean all the queues associated with a q_vector. all of them. not some, not most — all. she's thorough like that. 🧹✨

and then? she returns the amount of work done. that's it, that's the whole function. short and slay. 💅

like, that's a lot of friends, and honestly? main character energy for knowing all of them. 👑🔥

💀 friendly reminder bestie: these (9) pages are all kernel-internal API docs — this isn't a command you type in your shell, it's a function in the iavf driver source. don't go typing it into a terminal and wondering why nothing happens 😭🙈

---

anyway that's the whole page, and you ate it up, no crumbs. 🍓✨

sign-off time 🎀 — this little beauty came from the ./drivers/net/ethernet/intel/iavf source, dated October 2026, and the man page itself is iavf_napi_poll(9). mwah, love u, bye 💜🦋
