free_tx_ring(9)

💅 free_tx_ring(9) — from the Kernel API Manual ✨

okay so bestie, welcome to free_tx_ring 🎀 — yes, that's a section 9 kernel API page, and yes, we're gonna get through it together. Buckle up 🦋

---

🌸 NAME 🌸

free_tx_ring — free the TX descriptor ring 💫

---

⭐ SYNOPSIS ⭐

void free_tx_ring (struct device *dev , struct sxgbe_tx_queue *tx_ring ,
int tx_rsize );

that's the whole signature, no cap — copy it exactly like that 🫶

---

💖 ARGUMENTS 💖

• dev — the net device structure 🖥️ like, the actual network device we're talking about here
• tx_ring — the ring that's gonna be initialised 💍 (yes, the page literally says "initialised" for the ring you pass in — I'm just relaying the vibes)
• tx_rsize — the ring size 📏 that's it, that's the size

---

✨ DESCRIPTION ✨

so what does it actually do? per the page: this function initializes the DMA TX descriptor 🔥 that's the whole description, queen. no extra lore, no hidden paragraphs, nothing. it does the thing with the DMA TX descriptor and that's the tea ☕
