ieee80211_channel_equal(9)

📦 version 7.3.1, in nixpkgs unstable

💅 ieee80211_channel_equal 💅

okay so bestie, welcome to ieee80211_channel_equal — it lives in section 9 of the Kernel API Manual, which is the "kernel functions" section, so you already know this is driver-devel girlie territory 🧚. the whole page is literally just "are these two things the same channel," and honestly? she ate. let's get into it.

✨ NAME ✨

ieee80211_channel_equal — compare two struct ieee80211_channel, that's it, that's the whole job 💖

🦋 SYNOPSIS 🦋

bool ieee80211_channel_equal (struct ieee80211_channel *a , struct
ieee80211_channel *b );

so you call it like a normal function, you hand it two pointers, and it gives you back a bool. that's the vibe check. 🔥

🎀 ARGUMENTS 🎀

  • a — the 1st struct ieee80211_channel. she's the first one up, the main character of the comparison 🌸
  • b — the 2nd struct ieee80211_channel. she's the one getting compared to a, no pressure babe 🫶

⭐ RETURN ⭐

it returns true if the center frequency of a == the center frequency of b 💀 that's the entire comparison. not the flags, not the band, not any of the other little fields hanging out in there — literally just the center frequency. lowkey obsessed with how simple that is ngl ✨

heads up: this is part 1, bestie — there's more coming, don't go anywhere 💜

✨ SEE ALSO ✨

okay so this section is literally the group chat of the whole cfg80211 universe 🫶 and the first thing you need to know is where everybody lives: Kernel file ./include/net/cfg80211.h. that's the mothership. everything below is a page you can actually pull up, and bestie we are not skipping a single one 💅.

  • Scanning and BSS list handling(9) — yup, another section, and it brought friends: struct cfg80211_ssid(9), struct cfg80211_scan_info(9), struct cfg80211_scan_6ghz_params(9), struct cfg80211_scan_request(9), struct cfg80211_match_set(9), struct cfg80211_sched_scan_plan(9), struct cfg80211_bss_select_adjust(9), struct cfg80211_sched_scan_request(9), enum cfg80211_signal_type(9), struct cfg80211_inform_bss(9), struct cfg80211_bss_ies(9), struct cfg80211_bss(9), ieee80211_bss_get_elem(9), ieee80211_bss_get_ie(9)

anyway that's the whole crowd so far 🫶 go click through them, i'll wait 💖

...and the deep-cut support squad keeps going, because the kernel networking docs do not know how to stop (affectionate):

okay that's the "stop the interface / check the combinations" chunk, and honestly the range of girlbossery here is unmatched 💅

look at all these colour-change notifications living their best lives 🎨✨ (not a single one of them is doing the same job as our humble channel comparison, iykyk)

and that's the whole extended family right there — MLO reconf, NAN everything, the S1G frequency girlies, and the debugfs duo closing us out. 64 cross-references total, no cap. 🫶

okay bestie, that's the entire page, start to finish, and you absolutely ate it. 💖

for the receipts: this one lives in the source tree under ./include/net, it's dated October 2026, and it's filed as the ieee80211_channel_equal(9) man page. go forth and compare those channels with main character energy ✨🦋
