💖 octep_oq_fill_ring_buffers(9) 💖

okay so bestie, welcome to the Kernel API Manual — yes, that's the manual name, and yes, we're doing kernel driver internals today. This one lives in the networking corner of the kernel and it's genuinely iconic if you're into that sort of thing (iykyk). 🦋

✨ NAME ✨

octep_oq_fill_ring_buffers — fills the initial receive buffers for the Rx ring. literally its whole personality. 💅

---

🌸 SYNOPSIS 🌸

int octep_oq_fill_ring_buffers (struct octep_oq *oq );

---

🎀 ARGUMENTS 🎀

• oq — the Octeon Rx queue data structure. that's the vibe, that's the whole parameter list, no notes. 👑

---

⭐ RETURN ⭐

• 0 — slay, it worked, receive buffers got filled for all the descriptors. 🫶
• -1 — not slay. it means it failed to allocate a buffer, or it failed to map for DMA. crying, throwing up, etc. 😭
