STRUCT IEEE80211_VHT_OPERATION(9)

💖 struct ieee80211_vht_operation(9) — the Kernel API Manual glow-up 💖

okay so bestie, welcome to the struct ieee80211_vht_operation(9) page 💅 this is the Kernel API Manual and today we're learning about one (1) extremely specific little struct. she's small, she's VHT, she's iconic.

✨ NAME ✨

struct ieee80211_vht_operation — literally the VHT operation IE 🫶

🌸 SYNOPSIS 🌸

struct ieee80211_vht_operation {
    u8 chan_width;
    u8 center_freq_seg0_idx;
    u8 center_freq_seg1_idx;
    __le16 basic_mcs_set;
 };

that's the whole vibe. four members, no notes 👑

🎀 Members 🎀

• chan_width — the operating channel width, like how wide your whole situation is 📏
• center_freq_seg0_idx — center freq segment 0 index, no cap that's just what it is 🌀
• center_freq_seg1_idx — center freq segment 1 index, yes there's a second one, she contains multitudes 🌀🌀
• basic_mcs_set — the VHT Basic MCS rate set, aka the rate-set friend of the group 🌈

🦋 Description 🦋

so this structure is the "VHT operation element" — and that's a direct quote, I'm not even joking — exactly as described in 802.11ac D3.0 8.4.2.161. that's the reference, bestie, if you need receipts go read the spec 📖✨

💜 SEE ALSO 💜

the whole friend group, fr fr — they all hang out together:

• kernel file ./include/linux/ieee80211-vht.h — enum ieee80211_vht_opmode_bits(9)
• struct ieee80211_vht_mcs_info(9)
• enum ieee80211_vht_mcs_support(9)
• struct ieee80211_vht_cap(9)
• enum ieee80211_vht_chanwidth(9)
• ieee80211_get_vht_max_nss(9)

ngl if you're reading this struct you should probably at least skim struct ieee80211_vht_cap(9) too, they're literally besties 🤝

<s>ok that's the page</s> wait no, sign-off time 🎀 this one lives in ./include/linux, and the manual is dated October 2026 — mwah, stan, don't forget to man 9 struct ieee80211_vht_operation 💖✨🦋
