STRUCT NFP_NET_XSK_RX_BUF(9)

💅 struct nfp_net_xsk_rx_buf(9) 💅

okay bestie, welcome to the Kernel API Manual page for struct nfp_net_xsk_rx_buf — yes that's a mouthful, yes you're gonna say it out loud eventually, and yes it's literally just a software RX XSK buffer descriptor. slay. 🎀

---

✨ NAME ✨

struct nfp_net_xsk_rx_buf — software RX XSK buffer descriptor

that's it. that's the whole vibe. it's a descriptor. it lives in software. it's for RX. XSK flavored. periodt. 💅

---

🦋 SYNOPSIS 🦋

struct nfp_net_xsk_rx_buf {
    dma_addr_t dma_addr;
    struct xdp_buff *xdp;
};

look at her. two members. absolutely iconic. no notes. 👑

---

🌸 Members 🌸

• dma_addr — the DMA mapping address of the buffer. like, where the buffer actually lives as far as DMA is concerned. that's the whole gig. ✨
• xdp — the XSK buffer pool handle (for AF_XDP). yep, for AF_XDP, it says so right there, i'm not making this up. this is the handle to the XSK buffer pool. 🫶

okay so if you liked this one (and you did, don't lie), the kernel file ./drivers/net/ethernet/netronome/nfp/nfp_net.h has the whole friend group. go say hi to:

• struct nfp_net_tx_ring(9)
• struct nfp_net_rx_buf(9)
