STRUCT IWL_BA_WINDOW_STATUS_NOTIF(9)

💅 struct iwl_ba_window_status_notif(9) 💅

okay bestie so this is the page for struct iwl_ba_window_status_notif — it lives in your Kernel API Manual and it's literally all about the reordering window's status notification ✨. no cap, that's the whole gig.

---

🌸 NAME 🌸

struct iwl_ba_window_status_notif — reordering window's status notification 🎀

---

✨ SYNOPSIS ✨

here's the exact shape of it, don't touch, just vibe with it:

struct iwl_ba_window_status_notif {
    __le64 bitmap[BA_WINDOW_STREAMS_MAX];
    __le16 ra_tid[BA_WINDOW_STREAMS_MAX];
    __le32 start_seq_num[BA_WINDOW_STREAMS_MAX];
    __le16 mpdu_rx_count[BA_WINDOW_STREAMS_MAX];
 };

like, four arrays, all sized BA_WINDOW_STREAMS_MAX, all slaying in their own little way 🦋

👑 Members 👑

okay so let's meet the cast 💖

• bitmap — the bitmap of received frames, covering [start_seq_num + 0]..[start_seq_num + 63] ⭐ that's 64 of them if you're counting, and you should be counting.
• ra_tid — the packing on this one is giving ✨organized✨: bit 3:0 is the TID, bit 8:4 is the STA_ID, and bit 9 is the valid flag. yes ma'am, three things in one little field, iconic 🔥
• start_seq_num — the start sequence number of the bitmap. that's it. that's the whole job. 🫶
• mpdu_rx_count — the number of received MPDUs since entering D0i3 💀 (and yes it's counting from when you entered D0i3, not from whenever you feel like it)
