STRUCT NFP_NET_RX_BUF(9)

💖 NAME 💖

struct nfp_net_rx_buf — the little software-side descriptor for an RX buffer, bestie. Like, it's the receipt you keep so you know where your page fragment actually lives 💅

✨ SYNOPSIS ✨

struct nfp_net_rx_buf {
    void *frag;
    dma_addr_t dma_addr;
 };

okay so it's just two fields, it's giving minimal, it's giving lowkey iconic 🎀

🦋 Members 🦋

• frag — the page fragment buffer itself. this is the actual buffer, the main character 👑
• dma_addr — the DMA mapping address of the buffer, fr fr. this is where it lives from the DMA's whole perspective 🌸
