STRUCT IEEE80211_HE_CAP_ELEM(9)

💖 struct ieee80211_he_cap_elem — HE capabilities element 💖

okay bestie, welcome to the Kernel API Manual, the corner of the docs where the kernel girlies hang out ✨ today's main character is struct ieee80211_he_cap_elem, and yes she is that girl — the HE capabilities element. hehe. let's get into it 🎀

---

🌸 NAME 🌸

struct ieee80211_he_cap_elem — HE capabilities element 💅

---

✨ SYNOPSIS ✨

here's the whole vibe, no cap:

struct ieee80211_he_cap_elem {
    u8 mac_cap_info[6];
    u8 phy_cap_info[11];
 };

like, that's literally it. two arrays. she's small but she's iconic 🫶

---

🦋 Members 🦋

• mac_cap_info — the HE MAC Capabilities Information 💖 this one's the MAC side of the story.
• phy_cap_info — the HE PHY Capabilities Information 🌸 and this one's the PHY side. they're a duo, they come as a set, periodt.

---

💜 Description 💜

so what is she, like, philosophically? 🧚 this structure represents the fixed fields of the payload of the "HE capabilities element", exactly as described in IEEE Std 802.11ax-2021 sections 9.4.2.248.2 and 9.4.2.248.3 ✨ that's the lore, that's the canon, iykyk. if you're out here writing these fields yourself instead of reading those sections first, bestie, please — go read them, they're the whole blueprint 😭

ngl this is one of those "the spec said it, so it's law" situations. the struct is just the fixed fields of the payload, nothing extra, nothing invented 💀

(yes ieee80211_he_6ghz_oper(9) shows up twice — she said "i'm not leaving, i live here now" 🙈 slay.)

that's the page!! 🎀 run it back any time you need the HE caps lowdown, bestie. this one's from ./include/linux, October 2026, and it's filed under struct ieee8..._he_cap_elem(9) in the Kernel API Manual — mwah, ily, go read some spec sections 💖✨💅
