💅 iavf_fill_default_direct_cmd_desc — bestie edition

okay so this is a page from the Kernel API Manual, and honestly? it's a little one but it's an important one. sit down, grab a strawberry 🍓, and let's get into it.

---

✨ NAME ✨

iavf_fill_default_direct_cmd_desc — the AQ descriptor helper function. that's it, that's the whole vibe. it helps. it's a helper. 🫶

---

✨ SYNOPSIS ✨

void iavf_fill_default_direct_cmd_desc (struct libie_aq_desc *desc , u16
opcode );

literally just two things go in, and nothing comes back out (it's a void, she doesn't return anything, she's mysterious like that 💅).

---

✨ ARGUMENTS ✨

• desc — pointer to the temp descriptor (non DMA mem). it's the temp one bestie, not the DMA one, keep that energy straight 🎀
• opcode — the opcode can be used to decide which flags to turn off or on. so like, it's giving "flags toggle energy" — the opcode calls the shots on which flags get flipped 🔥

---

✨ DESCRIPTION ✨

Fill the desc with default values. that's the whole job. no cap, she fills it with defaults and she does it well 👑

✨ SEE ALSO ✨

okay and before I go — this page lives in ./drivers/net/ethernet/intel/iavf, and the version stamp on it is October 2026. so yeah, marking your calendar, she's dated, she's sourced, she's done. mwah 💖 🎀

ngl if you ever forget the flags logic just come back and reread the opcode bullet. it's short but it's carrying the whole meaning. periodt. 💀
