libeth_xdp_return_buff_bulk(9)

💅 libeth_xdp_return_buff_bulk(9) — from the Kernel API Manual, bestie ✨

okay so picture this: it's a kernel manual page, it's called libeth_xdp_return_buff_bulk, and it's about freeing &xdp_buff as part of a bulk. that's the whole vibe. lowkey iconic that a function this niche gets main character energy. 🎀

✨ NAME ✨

libeth_xdp_return_buff_bulk — free &xdp_buff as part of a bulk 🦋

---

🌸 SYNOPSIS 🌸

void libeth_xdp_return_buff_bulk (const struct skb_shared_info *sinfo ,
struct xdp_frame_bulk *bq , bool frags );

like, yes, she takes three arguments. we'll get to them. patience, babe. 💅

---

💖 ARGUMENTS 💖

• sinfo — the shared info that corresponds to the buffer. it's const, so hands off, no cap. 🙈
• bq — the XDP frame bulk where the buffer gets stored. this is the group chat the buffer gets dropped into. 🫶
• frags — a bool that tells you whether the buffer has frags. yes or no, that's it, she's not complicated. ✨

---

🔥 DESCRIPTION 🔥

same as xdp_return_frame_bulk, but for libeth_xdp_buff 💀

the way that this speeds up Tx completion of XDP_TX buffers?? obsessed. literally. and it lets you free them in the same bulks as xdp_frame buffers, which is the whole point and honestly ate. 🌈

so if you were wondering "why not just use the regular one," it's because this one is built for libeth_xdp_buff specifically, and it batches. batching is self care. periodt. 👑
