iavf_setup_rx_descriptors(9)

💅 iavf_setup_rx_descriptors — like, the iavf Kernel API Manual, bestie ✨

Okay so real talk, this page lives in the iavf Kernel API Manual, and it's about exactly one little function that does one very specific job: it goes and gets you some Rx descriptors. That's it. That's the whole vibe. 🎀

---

✨ NAME ✨

iavf_setup_rx_descriptors — allocate Rx descriptors 🦋

---

🌸 SYNOPSIS 🌸

int iavf_setup_rx_descriptors (struct iavf_ring *rx_ring );

---

💖 ARGUMENTS 💖

• rx_ring — the Rx descriptor ring you wanna set up, and yeah it's for one specific queue, not the whole squad. Think of it as the ring, the main character of this whole operation 👑

---

🌈 DESCRIPTION 🌈

So you call this bad boy and it returns 0 on success. That's the slay. ✨

If it fails? It returns a negative value. Not zero. Negative. So please, for the love of everything, actually check the return value, because a negative number is the function literally telling you "girl, something went wrong" 😭💀

No cap: 0 = good, negative = bad. Those are the only two outcomes here, and that is the entire description of this function's behaviour. Periodt. 💅
