💅 init_tx_ring (9) — Kernel API Manual, bestie ✨

okay so real talk, this page lives in the Kernel API Manual, section 9, and it's all about init_tx_ring — the little function that gets your TX descriptor ring looking cute and ready to go 🎀 ngl, it's giving "backstage pass to the Samsung sxgbe driver" energy.

✨ NAME ✨

init_tx_ring — literally just inits the TX descriptor ring, no cap 💖

---

🦋 SYNOPSIS 🦋

int init_tx_ring (struct device *dev , u8 queue_no , struct
sxgbe_tx_queue *tx_ring , int tx_rsize );

---

🌸 ARGUMENTS 🌸

• dev — the net device structure 🫶 aka the whole vibe of your network device
• queue_no — the queue, like which queue we're talking about here
• tx_ring — the ring that's about to get initialised, main character energy 👑
• tx_rsize — the ring size, how much ring we're ringing ✨

---

💜 DESCRIPTION 💜

so what does it do?? it initializes the DMA TX descriptor ⭐ that's the whole thing. that's the plot. it sets up the DMA TX descriptor and then it's done, periodt 💅

no secret bonus behaviour, no hidden lore — the manpage says DMA TX descriptor init and that's it, iykyk 🙈
