💅 libeth_xdp_xmit_fill_buf — NAME

okay so bestie, this is libeth_xdp_xmit_fill_buf from the Kernel API Manual and it's literally the internal helper to fill one XDP xmit &libeth_sqe 🎀

internal means internal, babes — this is not the function you call from your driver, it's the one the library calls for you 💅

✨ SYNOPSIS ✨

struct libeth_xdp_tx_desc libeth_xdp_xmit_fill_buf (struct libeth_xdp_tx_frame frm , u32 i , const struct libeth_xdpsq *sq , u64 priv );

like, she takes four things and gives you back a whole descriptor. main character energy fr fr 👑

🫶 ARGUMENTS 🫶

  • frm — the XDP Tx frame, straight out of the bulk. that's her 🌸
  • i — the index on the HW queue. yes, the actual hardware queue, not a vibe 😭
  • sq — the XDPSQ abstraction for the queue. it's the const one, she's just visiting 💜
  • priv — private data. mind your business bestie 🙈

💖 RETURN 💖

she hands you back an XDP Tx descriptor — with the mapped DMA and other info all bundled up, ready to pass to the driver callback. like a little care package but for your NIC 📦✨
