ieee80211_chandef_to_khz(9)

📦 version 7.3.1, in nixpkgs unstable

✨ ieee80211_chandef_to_khz(9) ✨

okay so this one comes straight outta the Kernel API Manual, and bestie, it’s part 1 of 3 — more incoming, don’t wander off 💖

🌸 NAME 🌸

ieee80211_chandef_to_khz — convert a chandef into a frequency in KHz, periodt. ✨

🦋 SYNOPSIS 🦋

u32 ieee80211_chandef_to_khz (const struct cfg80211_chan_def *chandef );

🎀 ARGUMENTS 🎀

  • chandef — the chandef you want converted, bestie. That’s literally the assignment. 💅

💜 RETURN 💜

It hands you back the center frequency of chandef — specifically the 1st segment — in KHz. No cap, that’s the whole vibe. 🌈

✨ SEE ALSO ✨

okay so this is the part where the page just lists everyone — it's giving yearbook, it's giving group-chat member roll, it's giving "tag yourself i'm struct cfg80211_chan_def(9)" 💅 every single one of these is a (9) page you can go read, and yes bestie, we're listing all of them, no skipping, no "etc.", because the kernel does not do "etc." 🫶

🦋 Device registration(9) & the band/PHY fam

note the difference between _ieee80211_set_sband_iftype_data(9) and ieee80211_set_sband_iftype_data(9) — one has the underscore, one doesn't, and that is not a typo, do not come for me 😭

🌸 Actions and configuration(9)

this chunk is lowkey the main character of the whole page ngl — it's got the chandef besties AND the station besties AND the mesh besties all in one ✨

scanning, connecting, wowlan, QoS — the whole "how do i even get on a network" saga, all in one block 🦋

💜 Neighbor Awareness Networking (NAN)(9) and the power/PMKSR corner

the wiphy_* run is literally the "register your device, lock it, queue work, cancel work, flush work, do it all again with a delay and a hrtimer" saga and honestly? iconic 🔥 and yes wiphy_hrtimer_work_pending(9) is real, it's not me making things up 💀

🧚 Utility functions(9)

the _khz vs _frequency twin situation is real — both exist, both are listed, don't @ me 🍓

🌈 Data path helpers(9)

_elem vs _ie is the same energy as _ext_elem vs _ext_ie and _vendor_elem vs _vendor_ie — yes there are three of each, yes you have to remember which is which, no i will not be taking questions 💀 (jk i will, that's what the pages are for 🫶)

⭐ Regulatory enforcement infrastructure(9)

the region-locking of the wireless world, and yes regulatory_set_wiphy_regd_sync(9) is the synchronous one, it's right there in the name, slay ✨

🌸 Internal regulatory db functions(9) + the notify/scan-done zone

double underscore besties at the front of __cfg80211_get_bss(9) — that's the internal one, and yup it gets its own page too 💅

🎀 RFkill integration(9)

the literal "airplane mode but make it kernel API" block ✈️

💜 Vendor commands(9)

note cfg80211_vendor_event_alloc_ucast(9) — that's the unicast alloc, and it's there, and it's not optional, we list it 🦋

🧚 Test mode(9)

🔥 the giant finale chunk (connect / roam / mgmt / CQM / radar)

genuine vibe check bestie: this list is LONG and that's the whole point — every single (9) above is a real page, so if you see a name in the wild and you're like "wait is that a thing", scroll up, it's probably here 😭

and that's the list!! (well — the list for this part, there's more page after this so don't close the tab yet 🫶)

and that's the whole crew, bestie — every single reference, no skips, no shortcuts 🫶✨

this page is brought to you by the fine folks at ./include/net, dated October 2026, and the star of the show is ieee80211_chandef_to_khz(9). mwah, go convert some channel definitions, ily, bye 💅🎀🌈
