libeth_xdp_save_stash(9)

💅 libeth_xdp_save_stash(9) — bestie's guide to the Kernel API Manual 🎀

okay so picture this: you're deep in the Kernel API Manual (yes, that's the manual name, we're fancy like that ✨) and you've stumbled onto libeth_xdp_save_stash. no cap, this one is a whole little moment. let me break it down for you 🫶

---

✨ NAME ✨

libeth_xdp_save_stash — literally converts an &xdp_buff into a libeth_xdp buffer stash 💖

---

🦋 SYNOPSIS 🦋

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

that's the whole signature, bestie. keep it verbatim, she's a specific girlie 💅

---

🌸 ARGUMENTS 🌸

• dst — the target libeth_xdp_buff_stash that we're gonna initialize. this is the little stash being born ✨
• src — the source XDP buffer. the origin story, the main character 👑

---

💜 DESCRIPTION 💜

so this is an external helper used by libeth_xdp_save_buff — which means, and I cannot stress this enough, do not call it directly. like, I know it's cute and tempting, but it's not for you, iykyk 🙈

what it actually does: it takes the fields from the passed XDP buffer and uses them to initialize the stash on the queue 🎀 that way, a partially received frame can be finished later, during the next NAPI poll. it's giving "to be continued…" energy 😭🔥

fr fr, that partial-frame thing is the whole point — the stash is basically the save file so the frame can pick up where it left off next poll 🌈
