stmmac_dma_operation_mode(9)

💖 NAME 💖

stmmac_dma_operation_mode — HW DMA operation mode. bestie, this is the stmmac_dma_operation_mode(9) page from the Kernel API Manual, and it's lowkey iconic. 💅

✨ SYNOPSIS ✨

void stmmac_dma_operation_mode (struct stmmac_priv *priv );

🎀 ARGUMENTS 🎀

• priv — driver private structure. that's the whole argument, no cap. 🫶

🦋 DESCRIPTION 🦋

okay so this function is used for configuring the DMA operation mode register in order to program the tx/rx DMA thresholds or Store-And-Forward mode. it's giving "settings glow-up" energy, and that's literally it. ✨
