igb_setup_rx_resources(9)

✨ NAME ✨

okay so bestie, welcome to igb_setup_rx_resources(9) from the Kernel API Manual 💖 this one is literally about allocating Rx resources (Descriptors). that's the whole name, no cap.

---

🌸 SYNOPSIS 🌸

int igb_setup_rx_resources (struct igb_ring *rx_ring );

---

🎀 ARGUMENTS 🎀

• rx_ring — the Rx descriptor ring for a specific queue that we're setting up. yes bestie, one ring, one queue, we're setting it up 💅

---

🦋 DESCRIPTION 🦋

so the vibe check here is simple: it returns 0 on success, and a negative value on failure. that's it. that's the whole function. no extra lore, no hidden flags — just 0 = slay, negative = not slay 😭
