STRUCT IEEE80211_VHT_CAP(9)

💖 struct ieee80211_vht_cap — VHT capabilities 💖

okay so bestie, welcome to the struct ieee80211_vht_cap page from the Kernel API Manual (that's the manual name, we're folding it in, you're welcome 🫶). This is genuinely one of those "small struct, big main character energy" situations, so let's get into it ✨

---

🌸 SYNOPSIS 🌸

struct ieee80211_vht_cap {
    __le32 vht_cap_info;
    struct ieee80211_vht_mcs_info supp_mcs;
 };

literally two fields. that's it. that's the whole vibe 💅

---

🎀 Members 🎀

• vht_cap_info — the VHT capability info, bestie. it's a __le32 and it's carrying the VHT capability info. slay.
• supp_mcs — the VHT MCS supported rates, in the form of a struct ieee80211_vht_mcs_info. that's where the MCS supported rates live 🦋

---

✨ Description ✨

so what even is this? This structure is the "VHT capabilities element" — and where do we get that definition from? straight from 802.11ac D3.0 8.4.2.160 👑 no cap, that's the citation, that's the source of truth. it's giving "showed up to the spec and quoted it exactly."

like, this is the actual element, not a lookalike, not a cover version. the VHT capabilities element, periodt 💀

ngl bestie, if you're here you're probably deep in some 802.11ac code. respect. 🌈
