stmmac_tx_clean(9)

💅 stmmac_tx_clean(9) — from the Kernel API Manual

okay bestie, so this page is literally called stmmac_tx_clean and it lives in the Kernel API Manual section 9 — yes, the driver-functions chapter, we love her 💖

---

✨ NAME ✨

stmmac_tx_clean — to manage the transmission completion 🌸

---

🎀 SYNOPSIS 🎀

int stmmac_tx_clean (struct stmmac_priv *priv , int budget , u32 queue ,
       bool *pending_packets );

---

🦋 ARGUMENTS 🦋

• priv — the driver private structure, aka her whole personality 🫶
• budget — the napi budget that limits how many packets this function is allowed to handle. boundaries, icon behavior
• queue — the TX queue index 🔥
• pending_packets — the signal to arm the TX coal timer ⏰

---

🌈 DESCRIPTION 🌈

So basically ✨ it reclaims the transmit resources after the transmission finishes. no cap.

And if some packets still need to be handled — which happens because of TX coalesce — you set pending_packets to true so that NAPI arms the TX coal timer 💅 periodt.

ngl bestie that SEE ALSO list is giving main character energy — like, every single stmmac function showed up to the group chat and we respect it 💀👑

this gorgeous girl came from ./drivers/net/ethernet/stmicro... and she's stamped October 2026 — put that in your calendar bestie, and remember: page stmmac_tx_clean(9), Kernel API Manual 💜✨🫶
