libeth_xdp_load_stash(9)

💅 libeth_xdp_load_stash(9) — Kernel API Manual, bestie edition 🎀

okay so you're looking at libeth_xdp_load_stash from the kernel API manual and honestly? it's a little niche, a little mysterious, and very much an "iykyk" situation. let's get into it ✨

---

🦋 NAME 🦋

libeth_xdp_load_stash — the glow-up where we recreate an &xdp_buff from a libeth_xdp buffer stash 💖

like, the stash had a whole makeover era and now it's coming back as a real buff. main character energy fr.

---

✨ SYNOPSIS ✨

void libeth_xdp_load_stash (struct libeth_xdp_buff *dst , const struct
libeth_xdp_buff_stash *src );

no cap, that's the whole signature. two pointers, one void, zero drama. 🌸

---

🎀 ARGUMENTS 🎀

• dst — the target libeth_xdp_buff you're initializing. this is the one getting the fitting room treatment, bestie 💅
• src — the source stash. this is where the vibes (and the data) are coming from 🫶

💀 DESCRIPTION 💀

okay so important heads up first: this is an external helper used by libeth_xdp_init_buff, and you should not call it directly. it's giving backstage-pass-only, not general admission 🙈

what it actually does: it recreates an onstack libeth_xdp_buff using the stash that got saved earlier. so like, the stash was the save file and this function is the "continue game" button. iconic 🎮✨

the only field left untouched is rxq, and that's because it gets initialized later, inside that function we mentioned a second ago (libeth_xdp_init_buff). so it's not forgotten, it's just on its own schedule, living its truth 🦋
