iavf_tx_timeout(9)

💅 iavf_tx_timeout — the "your Tx queue is having a moment" handler

okay so real talk, this page lives in the Kernel API Manual, section 9, and the star of the show is iavf_tx_timeout. Yes bestie, it's exactly what it sounds like: something in the transmit path went quiet for too long and now this function gets to deal with it. 🫶

---

✨ NAME ✨

iavf_tx_timeout — literally the "respond to a Tx Hang" girlie. That's the whole job description, no cap.

---

🌸 SYNOPSIS 🌸

void iavf_tx_timeout (struct net_device *netdev , unsigned int txqueue );

That's it. That's the signature. Two args, zero drama (well, some drama, see below). 🔥

---

🦋 ARGUMENTS 🦋

• netdev — the network interface device structure. you know, the whole netdev situation this hang is happening on. main character energy. 👑
• txqueue — the queue number that is timing out. like, specifically this one. not the others. this one's being extra. 💀

ngl, a "Tx Hang" is the kernel's way of saying a transmit queue stopped making progress, and this function is the one that gets called to respond to it. No inventing extra behaviour here — the page says respond, so we respond. periodt.

also, the source file itself is a whole vibe: ./drivers/net/ethernet/intel/iavf/iavf_main.c — that's where you go if you want the actual lore. 🌈

that's the whole page bestie, no filler, no skipped lines. 💜

signing off: this one came from the source tree at ./drivers/net/ethernet/intel/iavf, dated October 2026, and it's the iavf_tx_timeout(9) page — mwah, slay, go fix that transmit queue. 💅✨
