STRUCT CFG80211_HE_BSS_COLOR(9)

πŸ“¦ version 7.3.1, in nixpkgs unstable

πŸ’… struct cfg80211_he_bss_color β€” from the Kernel API Manual, bestie

Okay so picture this: you're deep in the kernel API manual (yes, the <italic>9</italic> one, that's the section, don't @ me) and you land on struct cfg80211_he_bss_color. And you're like, "what even is this." Bestie. It's literally the AP settings for BSS coloring. That's the whole vibe. AP config, but make it colorful. 🎨✨

✨ NAME ✨

struct cfg80211_he_bss_color β€” AP settings for BSS coloring πŸ¦‹

Like, this struct is the little squad of fields that holds the BSS coloring config for an access point. That's it, that's the name section, we ate. πŸ’…

🌸 SYNOPSIS 🌸

Here's the whole thing, character for character, no cap:

struct cfg80211_he_bss_color {
    u8 color;
    bool enabled;
    bool partial;
 };

Not me being obsessed with how tidy that is. Three members, zero drama. 🫢

πŸ‘‘ Members πŸ‘‘

Alright, time for the roll call β€” three members, and every single one of them is carrying their own little job. Let's go:

  • color β€” the current color. That's it, that's the field. It's a u8, it holds the current color, main character energy, periodt. 🌈
  • enabled β€” HE BSS color is used. So like, a bool that says whether HE BSS coloring is actually in play or just sitting there looking pretty. If it's on, it's on. πŸ’–
  • partial β€” define the AID equation. Yes bestie, this one is the ✨math✨ member. It's the flag that goes with defining the AID equation, and I need you to respect it. 🧚
ngl, partial is the one where you go "huh?" for a sec, but that's literally what the page says β€” define the AID equation. Keep it, don't invent extra lore. πŸ™ˆ

More parts coming, don't you dare close the tab β€” we're not done yet, bestie. πŸ’œ

Okay bestie, buckle up πŸ’… β€” the see-also list on this one is long. Like, actually unhinged. But we do not skip entries in this house, so every single cross-reference is right here, in the exact order the manpage gods put them. 🫢

First up, the source of truth itself:

  • Kernel file ./include/net/cfg80211.h β€” that's the header where all this magic lives ✨

Okay so the list keeps going, bestie β€” this SEE ALSO section is lowkey enormous and honestly it's giving "the whole friend group showed up to the party" πŸ’… grab a snack πŸ“, we're doing this.

Halfway-ish, don't bail on me now 🫢 the NAN girlies and the colour-change girlies are about to make their entrance:

And that's the whole squad πŸŽ€ sixty-four cross-references, every single one of them, no cap. If you were looking for the bss_color lore itself, it's all up above in the Members section β€” this was just the friend group.

Bestie note: this page lives in the kernel's networking headers, so if nothing here compiles the way you expect, check you're reading the matching version, mwah πŸ’œ

Sign-off time, iykyk ✨ this little beauty came straight out of ./include/net, dated October 2026, and it's filed under struct cfg80211_he_bss_color(9) in the Kernel API Manual. Slay, go forth, and may your colour changes never collide πŸ’…πŸ”₯
