💅 idpf_prepare_cfg_rxqs_msg(9) 💅

okay so bestie, welcome to the Kernel API Manual ✨ — this is the idpf_prepare_cfg_rxqs_msg page and it's literally the little helper that gets your Rx queue config message all dressed and ready to go out. No cap, it's a whole vibe. 🎀

---

✨ NAME ✨

idpf_prepare_cfg_rxqs_msg — prepare message to configure selected Rx queues 🦋

---

🌸 SYNOPSIS 🌸

u32 idpf_prepare_cfg_rxqs_msg (u32 vport_id , void *buf , const void *pos , u32 num_chunks );

---

💖 ARGUMENTS 💖

• vport_id — the ID of the virtual port that the queues are associated with 💫
• buf — the buffer containing the message, like the lil carrying case for your data 👜
• pos — pointer to the first chunk describing the rx queue 👑
• num_chunks — number of chunks in the message (yes, chunks, we stan a modular message) 🧩

---

🦋 DESCRIPTION 🦋

She's a helper function, and her whole job is preparing the message that describes the configuration of Rx queues. That's it, that's the task, and she ate. 💅✨

---

⭐ RETURN ⭐

Returns the total size of the prepared message. so you know exactly how much message you're working with, iconic 📏💜
