✨ wl1251_cmd_send(9) ✨

okay bestie, so this one is from the kernel API manual — it's a little function called wl1251_cmd_send, and honestly? it's giving "messenger of the firmware" 💌 like its whole job is literally just Send command to firmware. no cap.

---

🌸 NAME 🌸

wl1251_cmd_send — send a command to the firmware, that's the whole vibe 🫶

---

🦋 SYNOPSIS 🦋

int wl1251_cmd_send (struct wl1251 *wl , u16 id , void *buf , size_t len
);

like yes it returns an int, yes it takes those four things, and yes we're gonna walk through every single one 🔥

---

💅 ARGUMENTS 💅

okay so here's the cast, main character energy only:

• wl — the wl struct. she's the one everything hangs off of 💖
• id — the command id. this is how you tell firmware which command you're sending, iykyk 🎀
• buf — the buffer containing the command. ⚠️ important: it must work with dma — like do not play with this one, bestie, it's not a regular buffer, it has dma requirements and we respect them 🙈
• len — length of the buffer. yes, you gotta tell her how big it is 💀

---

👑 SEE ALSO 👑

• Kernel file ./drivers/net/wireless/ti/wl1251/cmd.c — literally the source, go look, it ate 🌟
• wl1251_cmd_interrogate(9)
• wl1251_cmd_configure(9)

and that's the whole friend group, slay 💜

---

🧚 little reminder: that buf dma thing is not a suggestion, it's a whole requirement. ty <3
