iwl_sta_id_or_broadcast(9)

💖 iwl_sta_id_or_broadcast(9) 💖

okay bestie, so this is a page straight out of the Kernel API Manual — it's iwl_sta_id_or_broadcast(9) and it's literally the tiny helper that saves your whole driver from a NULL-pointer meltdown. let's get into it ✨

---

✨ NAME ✨

iwl_sta_id_or_broadcast — return sta_id or broadcast sta 🎀

---

🌸 SYNOPSIS 🌸

int iwl_sta_id_or_broadcast (struct iwl_rxon_context *context , struct
       ieee80211_sta *sta );

like, it takes two args and hands you back an int, no cap 🫶

---

🦋 ARGUMENTS 🦋

• context — the current context. that's the one. the context you're in rn 💅
• sta — a mac80211 station 🌈

---

👑 DESCRIPTION 👑

so here's the vibe: in certain circumstances, mac80211 passes along a station pointer that might just be NULL 😭 — for example during TX or key setup. and when that happens, you can't just sit there with a null pointer, you need the broadcast station instead.

so this inline function wraps that whole pattern up for you. it's giving "one little helper, zero drama" ✨ main character energy fr fr.

---

🔥 RETURN 🔥

the station ID for the mac80211 station — or the broadcast one if it was NULL 💀➡️👑
