e1000_setup_rx_resources(9)

🌸 e1000_setup_rx_resources 💅

okay so bestie, welcome to the Kernel API Manual — section 9, kernel dev territory, and this little icon is all about getting your receive-side act together ✨. Grab a strawberry 🍓, sit down, and let's get into it.

✨ NAME ✨

e1000_setup_rx_resources — allocate Rx resources (Descriptors) 🎀

---

🦋 SYNOPSIS 🦋

int e1000_setup_rx_resources (struct e1000_adapter *adapter , struct
       e1000_rx_ring *rxdr );

---

💖 ARGUMENTS 💖

• adapter — the board private structure. yeah, the whole vibe of the nic lives in here 👑
• rxdr — the rx descriptor ring (for a specific queue) that we're setting up. literally one queue's worth of ring energy 🌀

---

🌈 DESCRIPTION 🌈

Returns 0 on success, negative on failure. that's it, that's the whole thing — no cap 😭. success gets you a happy little 0, and if it goes sideways you get a negative number back. periodt 💅

okay that's the whole page, mwah 💋 — this one came from ./drivers/net/ethernet/intel/e... and it's dated October 2026, still serving e1000_setup_rx_resources(9) realness. go set up those rings, bestie, you're gonna slay 🧚‍♀️💜
