cfg80211_bss_color_notify(9)

📦 version 7.3.1, in nixpkgs unstable

✨ NAME ✨

okay so this is the Kernel API Manual entry for cfg80211_bss_color_notify — and its whole job is literally to notify about a bss color event 💅✨

🎀 SYNOPSIS 🎀

int cfg80211_bss_color_notify (struct net_device *dev , enum
nl80211_commands cmd , u8 count , u64 color_bitmap , u8 link_id );

🌸 ARGUMENTS 🌸

  • dev — the network device 🫶
  • cmd — the actual event we want to notify, like that's the whole vibe of the call ⭐
  • count — the number of TBTTs until the color change happens ⏳
  • color_bitmap — representations of the colors that the local BSS is aware of 🌈
  • link_id — valid link_id in case of MLO or 0 for non-MLO 👑

💖 RETURN 💖

0 on success. Non-zero on error 😭🔥

✨ SEE ALSO ✨

okay bestie, this is the part where the man page goes "here's literally everyone else you should go meet" — it's a whole group chat of related pages, and the way it's just an endless list is giving "invited the entire contact list to the party" 💀 but every single one is here, no cap, in the exact same order.

The one that started it all, the source file itself, plus the intro-level reading:

Scan/BSS notification + lookup helpers 🦋

MLME + assoc response / failure plumbing — note the underscore double version again, __cfg80211_radar_event(9) also exists later, the underscore ones are the internal ones, iykyk 🙈

RFkill integration(9) — three pages, all wiphy_rfkill_*, short and sweet 💀

Weird frame reports + beacon reports — and the very last one, struct cfg80211_beaconing_check_config(9), the final boss of the list 👑

ok that's the whole list, bestie — every single reference, nothing cut, nothing renamed. go click through them like it's a wiki rabbit hole, you'll come out the other side lowkey a wireless expert 💅✨

okay bestie, buckle up, the reference list keeps going 💅 these are all the sibling pages you can go read next — same section, no heading repeat, we're just vibing through the rest of it ✨

the regulatory / beaconing girlies 🎀

registration, splitting, and friends 🦋

power, channels, and combos 👑

NAN, auth, and measurement stuff 🌸

the color squad (aka our main character's neighbors) 🌈

NAN again, debugfs, S1G, and the last few 🧚

and that's the whole list, bestie, we literally made it to the end 🫶
