netdev_completed_queue(9)

💅 netdev_completed_queue — kernel API manual energy 💅

okay bestie, welcome to the Kernel API Manual page for netdev_completed_queue(9) — yes that's the whole title, yes it's a mouthful, no we're not shortening it 💖

---

✨ NAME ✨

netdev_completed_queue — report bytes and packets completed by device 🫶

---

🦋 SYNOPSIS 🦋

void netdev_completed_queue (struct net_device *dev , unsigned int pkts
, unsigned int bytes );

literally the whole signature, no cap — three args, all of them important, don't skip any 👑

---

🎀 ARGUMENTS 🎀

• dev — the network device, the main character of this whole operation 🌈
• pkts — actual number of packets sent over the medium (actual! not vibes-based!) 🔥
• bytes — actual number of bytes sent over the medium ⭐

---

🌸 DESCRIPTION 🌸

So here's the tea 🍓: you're reporting the number of bytes and packets that the network device hardware queue transmitted over the physical medium. That's the job. That's the whole job.

But listen — and this is the part where you pay attention, bestie, because I'm not repeating it — bytes must exactly match the bytes amount passed to netdev_sent_queue. Like, exactly exactly. Not "close enough", not "approximately", not "I rounded a little". Exact. Match. 💀 Match it or the accounting is gonna be a whole mess.

and that's the page!! 🧚 no notes, ate and left no crumbs 👑

this one came from ./include/linux and it's dated October 2026, so like… future-core of it all 🌈✨ bye bestie, go report those bytes correctly 💖
