💖 nfp_net_rx_ring_alloc(9) — Kernel API Manual ✨

okay so bestie, welcome to the glow-up era of the kernel API manual, section 9, and today's main character is nfp_net_rx_ring_alloc. yes she's a function. yes she's iconic. let's get into it 🎀

---

🌸 NAME 🌸

nfp_net_rx_ring_alloc — literally allocates the resources for a RX ring. that's the whole vibe. resource-allocating queen 👑

---

✨ SYNOPSIS ✨

int nfp_net_rx_ring_alloc (struct nfp_net_dp *dp , struct nfp_net_rx_ring *rx_ring );

she takes two pointer besties and hands you back an int. no cap 🫶

---

🦋 ARGUMENTS 🦋

• dp — the NFP Net data path struct. the whole data-path situation, the big picture, the moment 💅
• rx_ring — the RX ring you want to allocate. this is the ring in question. the ring of the hour 🌈

---

⭐ RETURN ⭐

• 0 on success — slay, it worked, we love to see it 💖
• a negative errno otherwise — not slay, something went sideways, the errno will tell you what 😭

---

ngl bestie, this is the resource-allocation step — if it returns a negative errno, please actually check it and don't just vibe past it 🙈
