i40e_xsk_wakeup(9)

✨ i40e_xsk_wakeup ✨

Okay bestie, welcome to the i40e_xsk_wakeup page 💅 this is a Kernel API Manual entry, and it's giving "small function, big responsibilities" energy fr fr.

🌸 SYNOPSIS 🌸

int i40e_xsk_wakeup (struct net_device *dev , u32 queue_id , u32 flags );

That's the whole signature, no cap. She takes three args and hands you back an int 🫶

---

🎀 ARGUMENTS 🎀

• dev — the netdevice 💻 like, the actual network device we're talking about.
• queue_id — the queue id you wanna wake up ⏰ that's literally the whole job.
• flags — ignored in our case since we have Rx and Tx in the same NAPI. Yeah bestie, she's not even looking at it 🙈 don't take it personally, it's not you, it's the architecture.

---

🦋 DESCRIPTION 🦋

So what does she actually do? She Implements the ndo_xsk_wakeup — that's the mission statement, that's the whole vibe ✨

And the return value? Returns <0 for errors, 0 otherwise. Simple. Iconic. No notes 👑

Real talk: <0 means something went wrong, 0 means it's all good. That's the entire contract, so don't go reading extra meaning into it 💖
