STRUCT IWL_WOWLAN_INFO_NOTIF_V1(9)

🌸 struct iwl_wowlan_info_notif_v1(9) 🌸

okay bestie, so this is a page from the Kernel API Manual and it's literally all about struct iwl_wowlan_info_notif_v1 — the WoWLAN information notification. yes, WoWLAN, as in Wake-on-WLAN, the thing that lets your laptop hear the wifi calling while it's napping 😴✨

---

✨ NAME ✨

struct iwl_wowlan_info_notif_v1 — WoWLAN information notification. that's it, that's the whole vibe. it's the notification struct that carries all the wake-up gossip 💅

---

🎀 SYNOPSIS 🎀

struct iwl_wowlan_info_notif_v1 {
    struct iwl_wowlan_gtk_status_v3 gtk[WOWLAN_GTK_KEYS_NUM];
    struct iwl_wowlan_igtk_status_v1 igtk[WOWLAN_IGTK_KEYS_NUM];
    __le64 replay_ctr;
    __le16 pattern_number;
    __le16 reserved1;
    __le16 qos_seq_ctr[8];
    __le32 wakeup_reasons;
    __le32 num_of_gtk_rekeys;
    __le32 transmitted_ndps;
    __le32 received_beacons;
    __le32 wake_packet_length;
    __le32 wake_packet_bufsize;
    u8 tid_tear_down;
    u8 station_id;
    u8 reserved2[2];
 };

like, look at her. she's got arrays, she's got counters, she's got reserved padding at the end because alignment said so 🫶

👑 MEMBERS 👑

every field, one by one, no skips, we're doing the full tour:

• gtk — GTK data. the good stuff 🔥
• igtk — IGTK data. also iconic, different letters 💜
• replay_ctr — GTK rekey replay counter. it's counting replays, don't ask it to explain further, the original doesn't 😭
• pattern_number — number of the matched patterns. how many patterns matched, fr fr
• reserved1 — reserved. literally just sitting there holding space 🧚
• qos_seq_ctr — QoS sequence counters to use next. next up, bestie
• wakeup_reasons — wakeup reasons, see enum iwl_wowlan_wakeup_reason. the receipts of why you woke up 💀
• num_of_gtk_rekeys — number of GTK rekeys
• transmitted_ndps — number of transmitted neighbor discovery packets. yes "ndps" = neighbor discovery packets, she's networking 💅
• received_beacons — number of received beacons. beacons received, count 'em
• wake_packet_length — wakeup packet length
• wake_packet_bufsize — wakeup packet buffer size
• tid_tear_down — bit mask of tids whose BA sessions were closed in suspend state. so like, the BA sessions that got closed while suspended, as a bit mask 🌈
• station_id — station id
• reserved2 — reserved. second reserved, still reserved, still not doing anything 🙈

bestie heads up: this page is versioned (_v1, hello), and the family tree above quietly shows you _v3, _v5 and the unversioned one too — so if you're on a newer struct, check those pages before you go assuming anything 👀

and that's the page!! 🎀 source/version is the kernel doc tree at ./drivers/net/wireless/intel/i... (truncated in the original, not my fault 😭) and it's dated October 2026, footer reads struct iwl_...nfo_notif_v1(9) — mwah, slay, bye bestie 💖✨🦋
