STRUCT CFG80211_AP_UPDATE(9)

📦 version 7.3.1, in nixpkgs unstable

💖 struct cfg80211_ap_update(9) — Kernel API Manual 💖

okay so bestie, you found it: struct cfg80211_ap_update, straight out of the Kernel API Manual. this is the page for updating an AP that's already running, and it is so much chiller than it looks. let's get into it 🫶

✨ NAME ✨

struct cfg80211_ap_update — AP configuration update 💅

like, the whole vibe is: you already have an AP up and running and you just wanna tweak its config. that's the gig.

✨ SYNOPSIS ✨

struct cfg80211_ap_update {
    struct cfg80211_beacon_data beacon;
    struct cfg80211_fils_discovery fils_discovery;
    struct cfg80211_unsol_bcast_probe_resp unsol_bcast_probe_resp;
    struct cfg80211_s1g_short_beacon s1g_short_beacon;
 };

look at her. four members. clean. iconic. don't touch the semicolons, i'm serious 😭

🌸 Members 🌸

  • beacon — beacon data 🎀 literally the beacon stuff, that's the whole description and honestly? she said what she said.
  • fils_discovery — FILS discovery transmission parameters ✨ the transmission params for FILS discovery, that's the tea.
  • unsol_bcast_probe_resp — Unsolicited broadcast probe response parameters 📡 yes bestie, unsolicited, she's outgoing like that. these are the params for it.
  • s1g_short_beacon — S1G short beacon data 🦋 short beacon data for S1G. short queen behavior.

💜 Description 💜

okay so here's the actual point of this whole struct, and it's important so pay attention: this is a subset of struct cfg80211_ap_settings, and it exists specifically for updating a running AP 🔥

like, struct cfg80211_ap_settings is the whole entire fit, and struct cfg80211_ap_update is just the accessories you grab when you're already dressed and running out the door. subset. for updating. running AP. no cap 💅

more coming, bestie — don't go anywhere 🌈
