hfi1_netdev_rx_destroy(9)

💖 hfi1_netdev_rx_destroy — the kernel API glow-up 🎀

okay bestie, so this one is from the Kernel API Manual, section 9 (that's the kernel-functions section, iykyk). It's a tiny little cleanup function and honestly? She's the responsible friend who makes sure everyone actually leaves the party 🧹✨

---

🌸 NAME 🌸

hfi1_netdev_rx_destroy — so basically it decrements the netdevs counter, and when that counter hits 0, the napi gets deleted and the receive queues' memory gets freed 💅

lowkey iconic behaviour: she's the last one out, and she turns off the lights.

---

🦋 SYNOPSIS 🦋

int hfi1_netdev_rx_destroy (struct hfi1_devdata *dd );

(she takes one argument, she returns an int, no cap ✨)

---

💜 ARGUMENTS 💜

• dd — the hfi1 dev data

that's it. that's the whole argument list. one (1) parameter, and it's the dev data 🫶

👑 SEE ALSO 👑

the source file herself lives right here, in the kernel file:

💀 reminder bestie: destroy in the name is not a vibe, it's a job. counter goes down, and at 0 the napi is deleted and the receive queues' memory is freed. that's literally the whole plot. don't forget it 🍓
