💅 libie_ctlq_free_fq — kernel API manual, but make it make sense

okay so bestie, welcome to libie_ctlq_free_fq(9), a page from the Kernel API Manual ✨ — yes it's a real manual, yes it's section 9, and yes you're gonna understand it because I refuse to let you not.

---

✨ NAME ✨

libie_ctlq_free_fq — frees fill queue resources, including buffers 🫶 no cap, the buffers go too, it's a full cleanout not a half-cleanout.

---

🌸 SYNOPSIS 🌸

void libie_ctlq_free_fq (struct libie_ctlq_info *ctlq );

that's it. one function, one argument, returns void (so nothing comes back, it just does the thing and leaves 💅).

---

🎀 ARGUMENTS 🎀

• ctlq — the Rx control queue whose resources need to be freed. that's the one you're cleaning up. the Rx control queue. specifically that one 🦋

lowkey important: this one frees the fill queue resources and the buffers — the buffers are not surviving this. that's the whole point. 🧚
