stmmac_free_rx_buffer(9)

🦋 stmmac_free_rx_buffer — free RX dma buffers

okay so this is stmmac_free_rx_buffer(9), straight out of the Kernel API Manual, and it's a lil cleanup queen 💅 she frees the RX dma buffers, periodt.

✨ NAME ✨

stmmac_free_rx_buffer — free RX dma buffers 🎀

---

🌸 SYNOPSIS 🌸

void stmmac_free_rx_buffer (struct stmmac_priv *priv , struct
       stmmac_rx_queue *rx_q , int i );

no cap, that's the whole signature — three args, returns void, she gives nothing back and that's her vibe 🫶

---

💖 ARGUMENTS 💖

• priv — the private structure. your main character struct, the one holding everything 🫶
• rx_q — the RX queue. yes bestie, the queue specifically for RX 🌸
• i — the buffer index. which one we're freeing, iykyk ⭐
