stmmac_start_rx_dma(9)

✨ stmmac_start_rx_dma — start the RX DMA channel ✨

okay so you know that Kernel API Manual thing, the stmmac_start_rx_dma(9) page? yeah. that's this. hi bestie, welcome to the group chat 💖

---

🌸 NAME 🌸

stmmac_start_rx_dma — start RX DMA channel. that's it. that's the whole vibe. 💅

---

🎀 SYNOPSIS 🎀

void stmmac_start_rx_dma (struct stmmac_priv *priv , u32 chan );

---

🦋 ARGUMENTS 🦋

• priv — the driver private structure. yeah the whole personal bag of driver stuff, your main character struct 💫
• chan — the RX channel index. which receive channel we're talking about, queen 🫶

---

🔥 DESCRIPTION 🔥

This starts a RX DMA channel. that's the entire tea, no extra lore, it literally starts the receive DMA channel and that's what it does, periodt. 🎯

lowkey the shortest description in the whole driver, and honestly? iconic for that. 😌
