ca8210_set_cca_mode(9)

💅 ca8210_set_cca_mode — the kernel API manual, bestie edition

okay so picture this: it's ca8210_set_cca_mode(9), she's a function, she's in the kernel API manual, and she has exactly one job. Setting the clear channel assessment mode of the ca8210. That's it. That's the whole vibe. 🎀

---

✨ NAME ✨

ca8210_set_cca_mode — sets the clear channel assessment mode of the ca8210. no cap, that's literally what she does 🦋

---

🌸 SYNOPSIS 🌸

int ca8210_set_cca_mode (struct ieee802154_hw *hw , const struct wpan_phy_cca *cca );

---

💖 ARGUMENTS 💖

• hw — the ieee802154_hw of the target ca8210 👑 like, which ca8210 are we even talking about? this one. this is the one.
• cca — the CCA mode you want to set ✨ the actual mode. the whole point. the main character of the parameter list.

---

🔥 RETURN 🔥

0 or a linux error code. that's it bestie — zero means slay, anything else means the kernel has notes 💀

lowkey a flex that this all lives in ./drivers/net/ieee802154/ca8210.c — one file, one driver, one very extra family tree 🧚

and that's the page!! mwah 💅 this came from the ./drivers/net/ieee802154 source, dated October 2026, and it's the ca8210_set_cca_mode(9) moment — go set some CCA modes, bestie, you're gonna eat 🌈⭐
