STRUCT IWL_SSID_IE(9)

💖 NAME 💖

struct iwl_ssid_ie — the directed scan network information element, bestie ✨

So like, this lil struct is literally the thing that carries "hey, go look for this network" energy into a scan. It's giving instruction card. Obsessed.

---

🎀 SYNOPSIS 🎀

struct iwl_ssid_ie {
    u8 id;
    u8 len;
    u8 ssid[IEEE80211_MAX_SSID_LEN];
 };

Lowkey the whole struct is three fields and it still ate. Periodt.

---

🌸 MEMBERS 🌸

• id — the element ID 💅 that's literally its whole job
• len — the element length, aka how much of this thing is actually real
• ssid — the element (SSID) data itself, the actual main character 🫶

---

🦋 DESCRIPTION 🦋

Okay so here's the tea ☕ — up to 20 of these can show up in REPLY_SCAN_CMD, and which ones get picked is decided by the "type" bit field in struct iwl_scan_channel. So each channel gets to choose a different set of ssids from among those 20 entries. Not me loving the flexibility 😭

And ngl, the detail you can't skip: SSID IEs get transmitted in reverse order of entry. Yes, backwards. No cap, that's just how it is. 🔥

💜 That's the whole vibe check, bestie — 20 entries max, reverse order on the wire, no notes.

And before you go 🥺 — this page came from ./drivers/net/wireless/intel/i..., slapped with an October 2026 date, and it's filed under struct iwl_ssid_ie(9). Stan. 🍓🧚💖
