libeth_xskfq_create(9)

✨ libeth_xskfq_create — create an XSkFQ ✨

okay so this one's from the Kernel API Manual (libeth_xskfq_create(9)) and it's literally just one job: spin up an XSkFQ. that's it. that's the whole vibe. 💅

---

🌸 SYNOPSIS 🌸

int libeth_xskfq_create (struct libeth_xskfq *fq );

yep, one arg, returns an int, we love a simple signature fr fr 🫶

---

🎀 ARGUMENTS 🎀

• fq — the fill queue you wanna initialize. that's the one, bestie, hand it over 💖

---

🦋 DESCRIPTION 🦋

so what does it do? it allocates the FQEs (yes, all of them 😭) and initializes the fields that libeth_xdp is gonna need:

• number of buffers to refill
• refill threshold
• buffer len

like, it's giving "prep work before the main character shows up" energy. lowkey essential, highkey underrated. 👑

---

⭐ RETURN ⭐

• 0 on success ✨
• -errno otherwise 😭

so like, zero means slay, anything else means check your errno, bestie.
