💫 ieee80211_sta_current_bw(9) 💫

okay so bestie, welcome to the Kernel API Manual — yes that's the manual name, we're fancy now 👑 — and today's main character is ieee80211_sta_current_bw, which is literally just "hey, how much bandwidth can this STA actually use right now?"

---

✨ NAME ✨

ieee80211_sta_current_bw — get STA's current usable bandwidth 🦋

---

🌸 SYNOPSIS 🌸

enum ieee80211_sta_rx_bandwidth ieee80211_sta_current_bw (struct
link_sta_info *link_sta , struct cfg80211_chan_def *chandef , enum
ieee80211_sta_bw_direction direction );

like, the vibe: you hand it a link STA, a chandef, and a direction, and it hands you back an enum ieee80211_sta_rx_bandwidth. iconique 💅

---

🎀 ARGUMENTS 🎀

• link_sta — the (link) STA to get the bandwidth for 🫶 that's your girl right there
• chandef — the chandef for the channel the STA is on 📡 gotta know where she's sitting
• direction — the direction (to or from STA) 🔁 yes bestie, direction matters, it's giving nuance

---

🔥 RETURN 🔥

the maximum bandwidth that the station can/may (currently) use in the given direction ✨

like — key word currently — it's the max she's allowed right now, not some forever-promise, ngl 💀
