STRUCT IEEE80211_S1G_OPER_IE(9)

💅 struct ieee80211_s1g_oper_ie — S1G Operation element ✨

okay so this is a page from the Kernel API Manual, section 9, and honestly? it's a little struct with main character energy. it's struct ieee80211_s1g_oper_ie, and it's literally the S1G Operation element. let's get into it bestie 🫶

🌸 NAME 🌸

struct ieee80211_s1g_oper_ie — the S1G Operation element. that's it, that's the vibe. 💖

---

✨ SYNOPSIS ✨

here's the whole glow-up, laid out exactly how the kernel writes it:

struct ieee80211_s1g_oper_ie {
    u8 ch_width;
    u8 oper_class;
    u8 primary_ch;
    u8 oper_ch;
    __le16 basic_mcs_nss;
 };

look at her. five fields. no notes. 🔥

🎀 Members 🎀

• ch_width — S1G Operation Information Channel Width. how wide the channel is being, basically. the width of the moment 💅
• oper_class — S1G Operation Information Operating Class. the operating class, living its life in the S1G Operation Information.
• primary_ch — S1G Operation Information Primary Channel Number. the primary channel's number, no cap.
• oper_ch — S1G Operation Information Channel Center Frequency. the channel center frequency, iconic.
• basic_mcs_nss — Basic S1G-MCS and NSS Set. that's the whole label, don't @ me 🍓

🦋 Description 🦋

so what is this thing? this structure represents the payload of the "S1G Operation element" — and true to form, that's exactly as described in IEEE Std 802.11-2020 section 9.4.2.212. periodt. if you were looking for extra lore, there is none, this is the lore 📖✨

no cap: the spec section is 9.4.2.212 and that is your receipt. go read it if you want the full tea ☕

and that's the page!! 💜 it lives in ./include/linux, it's stamped October 2026, and it goes by struct ieee8..._s1g_oper_ie(9) — yeah the name got a little truncated in the header, she's mysterious like that 🙈 mwah, bye bestie 🌈⭐
