cfg80211_gen_new_bssid(9)

📦 version 7.3.1, in nixpkgs unstable

💖 cfg80211_gen_new_bssid(9) 💖

okay so bestie, welcome to the Kernel API Manual page for cfg80211_gen_new_bssid — yes i know that name is a mouthful, say it with me, we're gonna get through it together 🫶

✨ NAME ✨

cfg80211_gen_new_bssid — generate a nontransmitted BSSID for multi-BSSID 💅

like, literally what it says on the tin. it makes you a brand-new nontransmitted BSSID. iconic behaviour, no cap.

🌸 SYNOPSIS 🌸

void cfg80211_gen_new_bssid (const u8 *bssid , u8 max_bssid , u8
mbssid_index , u8 *new_bssid );

so it returns void — meaning it's not gonna hand you back a value, it just does the thing and dips 😌 the actual result lands in new_bssid, which you hand it as a pointer. we love an out-param moment.

🎀 ARGUMENTS 🎀

  • bssid — the transmitter BSSID. this is your main character, the one doing the transmitting 🦋
  • max_bssid — the max BSSID indicator, and bestie listen — this one gets taken from the Multiple BSSID element. that's where it lives. don't go looking anywhere else 👑
  • mbssid_index — the BSSID index, and this lil guy is taken from the Multiple BSSID index element. yes, index element. different element. keep them straight, i believe in you 💖
  • new_bssid — the calculated nontransmitted BSSID. this is where the magic gets written, so it's the calculated one, not the transmitted one. very demure, very mindful 🌸
ngl the naming on this whole family of symbols is a lot, so just remember: bssid in = transmitter, new_bssid out = nontransmitted. the two middles are just the raw numbers you pulled out of their respective elements 💀

and that's the whole function, bestie — short and sweet, it's giving tiny-but-loaded 🧚

💖 SEE ALSO 💖

okay bestie, this is the part where the page just … lists everything. and i mean everything. it's giving "group chat where someone adds all 300 of their mutuals to the same chat" energy 😭 like genuinely, this is the whole cfg80211 extended family and they ALL showed up to the party. take a breath, we're going through them 💅

the very first one is the source of truth, the mothership, the actual file these docs came from:

  • Kernel file ./include/net/cfg80211.h

and then the intro + device registration vibes:

  • Introduction(9) — where the whole saga starts, def start here if you're new 🫶

🌸 okay that's the whole page, bye 🌸

That's it, that's the manpage, you made it to the end, I'm so proud 🫶 This lil gem lives in ./include/net and the version of record is dated October 2026 — so if you're reading this in the future, hi, hope the kernel is still slaying. Now go write some code, bestie, you've got this ✨🔥👑
