💖 e1000e_setup_rx_resources(9) 💖

okay so bestie, welcome to the Kernel API Manual ✨ — this lil page is all about e1000e_setup_rx_resources, and honestly? she's a lil workhorse and we're gonna appreciate her.

---

🌸 NAME 🌸

e1000e_setup_rx_resources — allocate Rx resources (Descriptors) 🎀

like, she gets the receive side its stuff. that's the whole gig. no cap.

---

✨ SYNOPSIS ✨

int e1000e_setup_rx_resources (struct e1000_ring *rx_ring );

that's it. one function, one argument, she's lowkey minimal and we love that for her 💅

---

🦋 ARGUMENTS 🦋

• rx_ring — the Rx descriptor ring 👑 this is the ring you're setting up resources for, periodt.

---

🌈 DESCRIPTION 🌈

okay so here's the tea ☕ — this function does its thing and then tells you how it went:

• returns 0 on success 🎉 (slay, we love a clean zero)
• returns negative on failure 😭 (ngl, that's the "something went wrong" vibe)

that's literally the entire description, bestie. short, sweet, to the point. main character energy fr fr.
