hfi1_netdev_rx_init(9)

💅 hfi1_netdev_rx_init(9) — from the Kernel API Manual, bestie 🎀

okay so listen up, because this one is literally about counting but it's also about allocating, and that duality is so main character of it. ✨

---

🌸 NAME 🌸

hfi1_netdev_rx_init — increments the netdevs counter, no cap. and the first time you call it? it does the whole glow-up: allocates the receive queue data and calls netif_napi_add for every single queue. every one. 💖

---

✨ SYNOPSIS ✨

int hfi1_netdev_rx_init (struct hfi1_devdata *dd );

like, that's the whole vibe. one function, one pointer, one int return. clean. 🦋

---

🫶 ARGUMENTS 🫶

• dd — the hfi1 dev data. that's it, that's the whole argument. it's giving "minimalist icon" honestly. 👑

ok real talk for a sec: it increments a counter, and that first-call behavior means the allocation + the netif_napi_add calls only happen once, on that very first call. so don't be out here expecting a fresh alloc every time, bestie. 🩷
