🎀 libeth_xsk_tx_fill_buf(9) 🎀

okay so welcome to the Kernel API Manual page for this little internal helper bestie. It's giving backstage-kernel-energy, and we're here for it. 💅

---

🌸 NAME 🌸

libeth_xsk_tx_fill_buf — the internal helper that fills XSk XDP_TX &libeth_sqe. Like, it's literally the fill-the-sqe helper. No cap. ✨

---

✨ SYNOPSIS ✨

the signature is giving:

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

---

🎀 ARGUMENTS 🎀

• frm — XDP Tx frame from the bulk. That's the frame you're working with, bestie. 🦋
• i — index on the HW queue. Literally the spot on the hardware queue. ⭐
• sq — XDPSQ abstraction for the queue. The queue's whole abstraction situation. 🌈
• priv — private data. The private data, periodt. 💜

---

💖 RETURN 💖

Returns an XDP Tx descriptor with the synced DMA and other info to pass to the driver callback. So: descriptor, synced DMA, other info, driver callback. That's the whole vibe. Slay. 🔥
