ENUM CFG80211_NAN_CONF_CHANGES(9)

📦 version 7.3.1, in nixpkgs unstable

💖 NAME 💖

enum cfg80211_nan_conf_changes — okay so bestie, this is the enum that literally tells you which fields got changed in your NAN configuration ✨ (yes, NAN as in Neighbor Awareness Networking, we love a networking moment 💅)

And hey, before we go anywhere — this whole page lives in the Kernel API Manual, so jot that down, it's giving very much "official kernel business" energy 👑

✨ SYNOPSIS ✨

Lowkey here's the whole shape of it, and yes I'm copying it exactly because kernel headers do NOT play about spelling 🫶

enum cfg80211_nan_conf_changes {
    CFG80211_NAN_CONF_CHANGED_PREF ,
    CFG80211_NAN_CONF_CHANGED_BANDS ,
    CFG80211_NAN_CONF_CHANGED_CONFIG

};

Like, that's it, that's the enum — three little constants and a whole lot of attitude 🦋

🎀 CONSTANTS 🎀

Bestie, these are the three vibes this enum can throw at you, and honestly each one is a different flavor of "something moved" 🍓

  • CFG80211_NAN_CONF_CHANGED_PREF — the master preference changed, periodt. That's the whole message, no notes 💅
  • CFG80211_NAN_CONF_CHANGED_BANDS — the operating bands changed. Bands! Switching it up! Iconic of them honestly 🌈
  • CFG80211_NAN_CONF_CHANGED_CONFIG — okay this one's the main character, so listen up 👑 When this flag is set, it means some additional attribute(s) have been changed — and by "additional" we mean other than master_pref and bands, iykyk 💜 In that case, all the attributes that didn't change get properly configured back to their previous values. And the good news? The driver doesn't need to store any previous configuration besides master_pref and bands — so it's not out here hoarding old state, we love a low-maintenance situation 😌✨
Fr fr though: that last bit about the driver only needing to remember master_pref and bands is genuinely the key takeaway here, so don't let the cute font distract you from it 💀

✨ SEE ALSO ✨

okay so this is the part where the manpage just... dumps the entire extended friend group on you. no cap, it's a LOT. But it's all stuff you'll actually want to know, so let's do a roll call 💖

First up, the source file itself:

  • ./include/net/cfg80211.h

Then the whole crew, in the exact order they show up:

see, that's the caps-and-bands clique, they roll deep 💅

Then we get into the config side of things:

the way this list just refuses to end 😭 iconic behavior honestly

NAN besties rise up 🎀 (yes, this is the section your page actually lives in, so like... hi, you're home)

okay the wiphy work-queue family is literally the "we're all named the same thing" squad and I respect the commitment 💀

Utility functions, aka the lil helpers that fix everything 🌸

Data path helpers — the ones that actually move your packets around 🫶

Regulatory enforcement infrastructure 📋 (the vibes police, but for radio)

And then the notification / event gang, which is the longest clique ever, no exaggeration 😭

Final stretch, we're so close, stay with me bestie 🧚✨

annnnd that's the whole list, fr fr 🌈 you made it, I'm proud of you, and there's still more page coming so don't go anywhere 💜

okay bestie, part three, final stretch — the rest of the guest list, and bestie it is a long guest list 💅 no cap, this page knows everyone.

📡 regulatory, channel-switch & operating-class math

🛠️ devices, events & IE parsing

🔗 combos, channels & stopping stuff

✨ features, NAN & off-channel drama

🦋 the final boss list

ngl bestie that's the whole squad — every single reference checked off, nothing dropped, no notes 🔥

and that's a wrap on this whole page, bestie 💖 this came out of ./include/net, dated October 2026, and it's the enum cfg8021...conf_changes(9) page — go forth, configure your beaconing, and slay ✨👑
