cfg80211_s1...end_freq_khz(9)

📦 version 7.3.1, in nixpkgs unstable

🌸 NAME 🌸

cfg80211_s1g_get_end_freq_khz — bestie, this one gets you the end frequency of an S1G chandef. That's it, that's the whole job. 💅

(also hiiii, this page lives in the Kernel API Manual, section 9 — ok so now you know where to find it 🎀)

✨ SYNOPSIS ✨

u32 cfg80211_s1g_get_end_freq_khz (const struct cfg80211_chan_def *chandef);

ok so look at her 👑 — she takes one pointer to a const struct cfg80211_chan_def and she hands you back a u32. Simple. Clean. Iconic. No cap.

🦋 ARGUMENTS 🦋

  • chandef — literally the chandef to use. that's the one, that's the input, you pass it in and she does her lil thing with it 🫶

(nothing else in the list, bestie — one argument, one vibe, we love a low-maintenance queen 😭)

⭐ RETURN ⭐

she returns the chandef's ending frequency in KHz — as a u32, capital K, capital H, capital z, exactly like that 💖

🌈 note the units fr fr: KHz, not Hz, not MHz. don't come back here confused later, i'm warning you lovingly 🙈

and that's this part — more is coming, keep scrolling babe 💜

Okay so, before we get into the actual ✨SEE ALSO✨ of it all, bestie — this list is long. Like, "she kept scrolling" long. It's literally every single thing that lives in the kernel file below, so buckle up, we're doing this in~~ sections ~~ so your brain doesn't fall out. No cap, every single reference is here. 💅

📁 the kernel file that started it all 📁

  • ./include/net/cfg80211.h — the kernel file, the mothership, the whole reason this page exists 🎀

🌸 the intro girlies & the core ieee80211 building blocks 🌸

Bestie moment fr fr: that's the entire SEE ALSO, start to finish, zero skips, zero "etc." — every single (9) accounted for. If your eyes glazed over around wiphy_hrtimer_work_pending(9), that's valid tbh 😭

Anyway, don't touch that dial — there's more coming 💅✨

okay bestie, the see-also list is long so we're grouping it by vibe, but every single name is here, untouched, no cap 💅

also lowkey a whole mood that the source line is just ./include/net — she lives in the headers, that's her home address 🏠✨

and the final sign-off fr fr: this page is from ./include/net, dated October 2026, and it's the cfg80211_s1...end_freq_khz(9) page — yes the truncated name is iconic in a "my user id got cut off" way 💀✨ go read the rest of the s1g girlies, ily, bye 🫶💖
