ieee80211_get_channel_khz(9)

📦 version 7.3.1, in nixpkgs unstable

💖 NAME 💖

okay bestie, welcome to the ieee80211_get_channel_khz(9) page from the Kernel API Manual — this one is literally all about getting the channel struct from a wiphy for a specified frequency ✨

ieee80211_get_channel_khz — get the channel struct from wiphy for the specified frequency 💅

🌸 SYNOPSIS 🌸

struct ieee80211_channel * ieee80211_get_channel_khz (struct wiphy
*wiphy , u32 freq );

🎀 ARGUMENTS 🎀

  • wiphy — the struct wiphy you want to get the channel for 🦋
  • freq — the center frequency (in KHz) of the channel, no cap ⭐

✨ RETURN ✨

The channel struct from wiphy at freq 💖

🌈 SEE ALSO 🌈

okay bestie, deep breath. this is the part where the manpage goes "and here's literally everyone else in the family group chat." no cap, it's a long list. i've chunked it up so your eyes don't glaze over, but every single entry is here, in the original order, not one dropped. 🫶

first up, the source file itself and the intro-level pages:

the wiphy struct era, aka the main character arc 🔥:

✨ utility functions ✨ — iykyk, these are the useful ones:

regulatory drama, the sequel, plus internal db functions:

BSS handling + mlme mgmt, still going strong:

vendor commands + test mode, niche but iconic:

connection/roam notifications, the plot thickens:

last stretch, you ate this whole list fr fr 💖:

and that's the whole list, no crumbs left behind 🧚

…and the rest of the squad, fr fr — the whole cfg80211/ieee80211 group chat, all of it (9):

Like, that's the whole friend group 💜 — if you're the kind of person who reads a channel page all the way to the bottom, you're lowkey the main character of this manpage, no cap. Go read one of those, bestie, they're all right there 🫶

and that's the whole page!! 🎀 This lil masterpiece lives at ./include/net, it's the October 2026 era of ieee80211_get_channel_khz(9), and honestly? She ate. Go get those channel centers, bestie — slay 💅✨🦋
