cfg80211_cqm_rssi_notify(9)

👑 cfg80211_cqm_rssi_notify(9) 👑

okay so this is from the Kernel API Manual, and bestie, it's literally the cfg80211_cqm_rssi_notify page — the one that tells you about connection quality monitoring rssi events 💖

---

✨ NAME ✨

cfg80211_cqm_rssi_notify — connection quality monitoring rssi event 🎀

✨ SYNOPSIS ✨

void cfg80211_cqm_rssi_notify (struct net_device *dev , enum
       nl80211_cqm_rssi_threshold_event rssi_event , s32 rssi_level , gfp_t gfp
       );

no cap, that's the whole signature — four args and a void return, she's giving "I do the thing and I don't hand you anything back" energy 💅

✨ ARGUMENTS ✨

• dev — the network device 🌸 like, the actual net_device this whole thing is happening on
• rssi_event — the triggered RSSI event ⚡ the one that fired, type enum nl80211_cqm_rssi_threshold_event
• rssi_level — new RSSI level value or 0 if not available 🫶 so if you've got a fresh number, drop it here; if not, 0 is the vibe
• gfp — context flags 🧚 the usual gfp_t situation

✨ DESCRIPTION ✨

so the way this works: this function gets called when a configured connection quality monitoring rssi threshold reached event occurs 🔥 that's it, that's the whole job. something crossed the line you set up, and this is the notification that goes out about it. iconic behavior honestly 💜

part 2 is coming, don't go anywhere ✨
