STRUCT IWL_WOWLAN_INFO_NOTIF_V5(9)

💅 struct iwl_wowlan_info_notif_v5 — WoWLAN information notification

okay so bestie, welcome to the Kernel API Manual ✨ — this page is all about one very specific little struct from the iwlwifi firmware API, and honestly? she's doing a lot. buckle up 🎀

She's the WoWLAN information notification — like the little gossip report your Wi-Fi card sends you after it's been napping (WoWLAN = wake-on-wireless-LAN, iykyk). 💤📡

✨ SYNOPSIS ✨

struct iwl_wowlan_info_notif_v5 {
    struct iwl_wowlan_gtk_status_v3 gtk[WOWLAN_GTK_KEYS_NUM];
    struct iwl_wowlan_igtk_status_v1 igtk[WOWLAN_IGTK_KEYS_NUM];
    struct iwl_wowlan_igtk_status_v1 bigtk[WOWLAN_BIGTK_KEYS_NUM];
    __le64 replay_ctr;
    __le16 pattern_number;
    __le16 qos_seq_ctr;
    __le32 wakeup_reasons;
    __le32 num_of_gtk_rekeys;
    __le32 transmitted_ndps;
    __le32 received_beacons;
    u8 tid_tear_down;
    u8 station_id;
    u8 num_mlo_link_keys;
    u8 tid_offloaded_tx;
    struct iwl_wowlan_mlo_gtk mlo_gtks[];
};

like, look at her. she's a whole flex 💪 the way this struct just has everything.

🌸 Members 🌸

• gtk — the GTK data 💖 (that's the group temporal key, if you were wondering — the group-chat key, if you will 🫶)
• igtk — the IGTK data ✨
• bigtk — the BIGTK data 🎀 (yes, that's the actual name. big. iconic.)
• replay_ctr — the GTK rekey replay counter 🔁 — she's counting replays, no cap
• pattern_number — how many matched patterns there were 🧚 (as in, how many of your wake-up patterns actually hit)
• qos_seq_ctr — the QoS sequence counters to use next ⏭️ like, the up-next numbers
• wakeup_reasons — the whole reason we're here!! the wakeup reasons 🌈 — check enum iwl_wowlan_wakeup_reason for the full tea
• num_of_gtk_rekeys — how many GTK rekeys happened 🔢
• transmitted_ndps — how many neighbor discovery packets got transmitted 📨 (ndp = neighbor discovery packet, she's social fr fr)
• received_beacons — how many beacons were received 🛎️ little Wi-Fi lighthouses
• tid_tear_down — a bit mask of TIDs whose BA sessions got closed while in suspend state 💀 like, sessions that got dropped mid-nap
• station_id — the station id 🪪
• num_mlo_link_keys — how many struct iwl_wowlan_mlo_gtk structs come following this notif 👀 (they trail behind her, main character + entourage energy)
• tid_offloaded_tx — the TID the firmware uses to transmit data packets while in wowlan 🚀 (not you. the firmware. she's handling it.)
• mlo_gtks — an array of GTKs, and its size is literally num_mlo_link_keys 🦋 (that's the flex — flexible array member, we love a variable-length queen)

ngl, if you're poking at the flexible array member mlo_gtks, remember its size is entirely determined by num_mlo_link_keys — so read that field first. 🙈
