STRUCT IEEE80211_S1G_BCN_COMPAT_IE(9)

🎀 struct ieee80211_s1g_bcn_compat_ie(9) 🎀

okay bestie, welcome to the Kernel API Manual, section 9 — this is the page for struct ieee80211_s1g_bcn_compat_ie, and yes it's a whole struct page, but it's a slay little struct so stay with me 💖

---

✨ NAME ✨

struct ieee80211_s1g_bcn_compat_ie — the S1G Beacon Compatibility element, literally.

---

🦋 SYNOPSIS 🦋

here's the whole vibe, character for character, no notes:

struct ieee80211_s1g_bcn_compat_ie {
    __le16 compat_info;
    __le16 beacon_int;
    __le32 tsf_completion;
 };

three fields, immaculate energy, that's her 👑

---

🌸 MEMBERS 🌸

let's meet the cast, one by one:

• compat_info — Compatibility Information. that's the whole description, she's mysterious like that 🙈
• beacon_int — Beacon Interval. intervals are her whole thing 💅
• tsf_completion — TSF Completion. yes queen, finish the TSF ✨

---

💜 DESCRIPTION 💜

so what is this actually, you ask? bestie, it's this: this structure represents the payload of the "S1G Beacon Compatibility element" as described in IEEE Std 802.11-2020 section 9.4.2.196. that's it, that's the whole lore — it's a payload holder for that element, per that exact section. no cap 🫶

if you're out here guessing at what the fields do beyond their names, don't — the spec (IEEE Std 802.11-2020 section 9.4.2.196) is the main character here, iykyk 📖
