stmmac_stop_tx_dma(9)

💖 NAME

okay so bestie, welcome to stmmac_stop_tx_dma(9) from the Kernel API Manual — the name is literally "stop TX DMA channel". It’s giving one-job main character energy: stop a TX DMA channel. periodt. 💅

✨ SYNOPSIS

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

That’s the whole signature, bestie — copy it exactly, no freestyle retyping. 🫶

🎀 ARGUMENTS

• priv — driver private structure. It’s the driver’s private struct, and yes, the description is that simple. slay.
• chan — TX channel index. Which TX channel? The index one. iykyk. 💖

🦋 DESCRIPTION

This stops a TX DMA channel. No cap, that’s the plot: it stops a TX DMA channel. The way this function is literally just “stop a TX DMA channel” and nothing else — iconic minimalism. ✨
