cfg80211_del_sta(9)

✨ cfg80211_del_sta ✨

So like, cfg80211_del_sta(9) is the Kernel API Manual page, and bestie, it's literally about telling userspace that a station just got yeeted 💅

---

🌸 NAME 🌸

cfg80211_del_sta — notify userspace about deletion of a station 🎀

---

🦋 SYNOPSIS 🦋

void cfg80211_del_sta (struct wireless_dev *wdev , const u8 *mac_addr ,
gfp_t gfp );

---

💖 ARGUMENTS 💖

• wdev — the wireless device, no cap 🫶
• mac_addr — the station's address. For MLD station, MLD address is used. 👑
• gfp — allocation flags ✨

🌈 SEE ALSO 🌈

okay bestie, deep breath. this is the part where the page just... name-drops everyone it's ever met. and it has met everyone. every single one of these is a (9) page, so it's basically one giant family reunion and we're standing at the door greeting all of them. grab a snack, we're doing the whole guest list. 💖
