STRUCT IEEE80211_HT_CAP(9)

💖 struct ieee80211_ht_cap(9) 💖

okay bestie, gather round, because today we're looking at struct ieee80211_ht_cap from the Kernel API Manual, and honestly? she's kind of a big deal. this is the HT capabilities element — yes, the High Throughput one, the 802.11n era glow-up. sit down, hydrate, let's get into it 🫶

✨ NAME ✨

struct ieee80211_ht_cap — the HT capabilities element, no cap 💅

---

🎀 SYNOPSIS 🎀

here's the whole struct, literally typed out exactly, don't come for me:

struct ieee80211_ht_cap {
    __le16 cap_info;
    u8 ampdu_params_info;
    struct ieee80211_mcs_info mcs;
    __le16 extended_ht_cap_info;
    __le32 tx_BF_cap_info;
    u8 antenna_selection_info;
 };

look at her. six fields. immaculate. 🌸

---

🌈 Members 🌈

• cap_info — HT Capability Information, aka the main character field that sets the whole vibe ✅
• ampdu_params_info — A-MPDU Parameters, the aggregation details, iykyk 📦
• mcs — Supported MCS Set, and it's a whole struct ieee80211_mcs_info of its own, so she's got layers ✨
• extended_ht_cap_info — HT Extended Capabilities, the bonus features 🦋
• tx_BF_cap_info — Transmit Beamforming Capabilities, literally pointing the signal right at you 🔥
• antenna_selection_info — ASEL Capability, choosing her antennas like she's choosing an outfit 💅

---

🌸 Description 🌸

so here's the lore: this struct represents the payload of the "HT Capabilities element", exactly as described in IEEE Std 802.11-2020 section 9.4.2.55. that's it, that's the whole job — she is the payload. iconic behaviour, honestly 👑
