__free_dma_r...sc_resources(9)

💖 NAME 💖

okay so bestie, welcome to the Kernel API Manual ✨ this is the page for __free_dma_rx_desc_resources — it literally frees RX dma desc resources (per queue) 💅 no cap, that’s the whole name.

✨ SYNOPSIS ✨

here’s the signature, copy it exactly or the compiler will side-eye you 😭

void __free_dma_rx_desc_resources (struct stmmac_priv *priv , struct
       stmmac_dma_conf *dma_conf , u32 queue );

🎀 ARGUMENTS 🎀

• priv — the private structure, periodt 🫶
• dma_conf — structure to take the dma data, slay ✨
• queue — RX queue index, iykyk 🎀
