cfg802154_g...e_short_addr(9)

🎀 NAME 🎀

cfg802154_get_free_short_addr — bestie, this is the one that gets you a free address among the known devices 💅

---

✨ SYNOPSIS ✨

__le16 cfg802154_get_free_short_addr(struct wpan_dev *wpan_dev);

Like, that's literally the whole vibe. One function, one argument, one __le16 coming back at ya 🦋

---

🌸 ARGUMENTS 🌸

• wpan_dev — the wpan device 👑 that's it, that's the whole argument, she's lowkey undemanding

---

💖 RETURN 💖

A random short address, expectedly unused on our PAN ✨

No cap, the key word here is expectedly — it's random, so it's giving "probably fine, probably unused" energy, not "guaranteed nobody has this address" energy 🫶
