📦 version 7.3.1, in nixpkgs unstable

💖 cfg80211_chandef_dfs_cac_time — NAME ✨

okay so bestie, this is from the Kernel API Manual, section 9, and it does exactly one thing: cfg80211_chandef_dfs_cac_time gets you the DFS CAC time (in ms) for a given channel definition. that's it, that's the whole vibe. 🎀

🌸 SYNOPSIS 🌸

unsigned int cfg80211_chandef_dfs_cac_time(struct wiphy *wiphy,
                                           const struct cfg80211_chan_def *chandef);

literally just hand it a wiphy and a chandef and it hands back an unsigned int. no cap. ✨

🦋 ARGUMENTS 🦋

  • wiphy — the wiphy you wanna validate against. that's the one, that's your reference point 🫶
  • chandef — the channel definition to check. this is the thing being inspected, main character energy fr 💅

🔥 RETURN 🔥

it gives you back the DFS CAC time (in ms) that applies for this channel definition. yes, milliseconds, so keep that in mind before you go doing math with it 😭

ngl the units matter here — it's ms, not seconds, not whatever your heart tells you 💀

✨ SEE ALSO ✨

okay so this is the part where the page just… lists everyone 💀 and bestie, it's a LOT. Like, the whole squad. Everyone who's ever been in the cfg80211 group chat is tagged here. If you're reading this page and you're like "wait who?", this is your reading list — every single one of these is another manpage waiting for you. No cap. 🫶

The source of truth for all of it lives in the kernel file ./include/net/cfg80211.h — that's the main character right there 👑 — and then the references, in order, are:

Like… iconic roster honestly 👑 every last one of them. If you actually read all of these, you're not just built different, you're built correct 🫶 and the pages don't stop here, so keep scrolling bestie ✨

okay so the SEE ALSO list literally does not stop, and honestly? respect. here's the rest of the squad, one by one, no skips, no cuts, bc we do not do "etc." in this house 💅

like… sixty-six cross-refs, bestie. sixty-six!! that's not a SEE ALSO, that's a whole group chat with read receipts on 🫶 every single one of them is a real page you can pull up with the (9) suffix, so go be nosy, that's literally what this section is for ✨

and that's a wrap on this page 💖 source lives in ./include/net (yes, the include tree, she's cozy in there), and the date stamp on this edition is October 2026. go forth, check your CAC time, and slay 🎀🌸🦋
