ieee80211_channel_to_khz(9)

📦 version 7.3.1, in nixpkgs unstable

💖 ieee80211_channel_to_khz 💖

okay so bestie, welcome to the Kernel API Manual, section 9 — this is ieee80211_channel_to_khz(9) and honestly? it's giving "tiny function, big main character energy" ✨ it does exactly one thing and it does it flawlessly, we love a focused queen 👑

🌸 NAME 🌸

ieee80211_channel_to_khz — converts an ieee80211_channel into a frequency in KHz, no cap 💅

like, that's it. that's the whole vibe. channel in, frequency out 🦋

✨ SYNOPSIS ✨

u32 ieee80211_channel_to_khz (const struct ieee80211_channel *chan );

so you hand it a pointer to an ieee80211_channel and it hands you back a u32. simple. clean. iconic 🎀

🫶 ARGUMENTS 🫶

  • chan — the struct ieee80211_channel you want converted, bestie. that's the one. the whole assignment. give it the channel and it'll do the glow-up into KHz for you 💖 (it's a const struct ieee80211_channel *, so it's just looking, not touching — respectful king 👑)

⭐ RETURN ⭐

returns the corresponding frequency, in KHz 🔥 that's the u32 right there. frequency secured, vibe check passed, periodt 💅

(more parts incoming — hold that thought bestie 🧚💜)

🌈 SEE ALSO 🌈

okay bestie, this is the part where we list literally everyone else in the cfg80211 friend group, because this function does not exist in a vacuum, she has a whole extended family 💅 every single one of these is a real page you can go read, and yes, there are a LOT of them. Buckle up 🎀

First up, the source of truth and the OGs:

Then we slide into Actions and configuration(9) territory and honestly this chunk ate 👑

And the wiphy lore — registration, refcounting, locking, work queues, the whole backstage pass 🎟️

Now the section our girl actually lives in — Utility functions(9) 🧰💖 (hi, that's us, we're in this list):

Data path helpers(9) — packets doing cardio 🏃‍♀️💨

Regulatory enforcement infrastructure(9) and Internal regulatory db functions(9) — the rules committee, do not mess with them 🚨

Then the event/notification crowd — everything that tells userspace "hey, something happened" 📣

RFkill integration(9) — the "airplane mode but make it ✨" crew:

Vendor commands(9) — where drivers go off-script, respectfully 💅

Test mode(9) — for the girlies who like to poke things 🧪

And the connection / roaming / station-bookkeeping besties, aka the rest of the whole entire world 🌍

ngl that's a LOT of cross-references and we're not even done — the list literally ends on a trailing comma in the original, so yeah, there's more coming 😭 don't go anywhere bestie 🫶

okay that's the whole list, we're done, you survived the cross-reference marathon 💀✨ Go read the ones you actually need and pretend the rest was a vibe check you passed. So proud of you bestie 🫶

This page comes from ./include/net, dated October 2026, and it's filed under ieee80211_channel_to_khz(9) — that's the source, the date, and the name of the page all in one little footer bow 🎀 ily, go convert some channels 💜
