ieee80211_get_he_iftype_cap(9)

📦 version 7.3.1, in nixpkgs unstable

💅 ieee80211_get_he_iftype_cap(9)

okay so bestie, this is from the Kernel API Manual — section 9, kernel routines, the whole vibe 🎀 — and it's literally the function that hands you back the HE capabilities for one specific iftype on one specific sband. no cap, that's the entire plot.

✨ NAME ✨

ieee80211_get_he_iftype_cap — returns the HE capabilities for an sband's iftype 🦋

🌸 SYNOPSIS 🌸

const struct ieee80211_sta_he_cap * ieee80211_get_he_iftype_cap (const
struct ieee80211_supported_band *sband , u8 iftype );

like, copy it exactly, i'm not kidding, every const and every space in that parameter list matters 💀

🫶 ARGUMENTS 🫶

  • sband — the sband you want us to search for the iftype on 🔍 literally the band we're digging through, bestie.
  • iftype — an enum nl80211_iftype. yes, that's the type, go off king 👑 it's the interface type you're asking about.

⭐ RETURN ⭐

it gives you back a pointer to the struct ieee80211_sta_he_cap — that's the good stuff, the actual capabilities 🎀 — or NULL if none is found. and if you get NULL, that's your sign, don't dereference it, i'm begging 🙈

okay so this is the part of the page where it basically points at the entire wireless subsystem and goes "you should probably know all of these too" 😭 and bestie it is a list. We are not skipping a single one. Every reference, in order, no cap.

Kernel file ./include/net/cfg80211.h — yes, the whole file, iconic behavior honestly.

That first cluster is like the main cast of the capability universe 💫 and yes, ieee80211_get_eht_iftype_cap(9) and ieee80211_get_uhr_iftype_cap(9) are literally the sibling functions of the one this page is about, so the vibe check makes sense.

the cfg80211_chandef_* girlies ate, honestly — that's a whole squad 🎀

NAN, PMSR, and the wiphy family — this section is genuinely a family reunion 😭

the whole wiphy lifecycle PLUS the workqueue/hrtimer work girlies — this part is lowkey the backbone of everything and it shows 💪

channel conversions, header lengths, cfg80211_find_* — all the practical little helpers that make you go "oh thank god someone wrote that" 🫶

regulatory + BSS handling + MLME notifications — this is the "adulting" section of the list and it did not miss 👑

and that is genuinely every single reference on the page, bestie — connect/roam/disconnect, mgmt RX/TX status, CQM notifications, radar and CAC events, all of it 💅✨ no skips, no shortcuts, not me being thorough or whatever 😭

Okay so the SEE ALSO list literally does not stop, and honestly? Respect. Here's the rest of the squad, all in their own little (9) era:

And that's the whole page, bestie — you made it to the end, I'm so proud 🫶💖

ngl this one lives in ./include/net, dated October 2026, and its official title is ieee80211_get_he_iftype_cap(9) — go forth and use it responsibly ✨💅🎀
