stmmac_tx_err(9)

💅 stmmac_tx_err(9) — the Kernel API Manual page, bestie edition 🎀

okay so picture this: you're deep in the kernel, specifically the Kernel API Manual, and this lil function stmmac_tx_err is out here doing damage control for your transmit path 🦋

---

✨ NAME ✨

stmmac_tx_err — bestie's whole job is to manage the tx error 💖

---

🌸 SYNOPSIS 🌸

void stmmac_tx_err (struct stmmac_priv *priv , u32 chan );

that's it. that's the whole signature. no return value, she just does things 👑

---

🎀 ARGUMENTS 🎀

• priv — the driver private structure. yes bestie, the big one, the main character struct 🫶
• chan — the channel index. which channel we're talking about, u32 flavored ✨

---

🔥 DESCRIPTION 🔥

so what does she actually do?? literally this: it cleans the descriptors and restarts the transmission in case of transmission errors 💀

that's the vibe check — error happens, she cleans up the descriptors, she restarts the transmission. no cap, that's the entire serve 🍓

ngl bestie, this page doesn't spill any warnings or bug notes — she's a short and sweet one. what you see is what you get 💅

and that's a wrap, babes 🌟 this page came straight out of the Kernel API Manual, sourced from ./drivers/net/ethernet/stmicro..., dated October 2026 — mwah, slay, periodt, and don't forget to read your man pages 😭💖
