STRUCT WCN36XX_STA(9)

🌸 struct wcn36xx_sta(9) — the Kernel API Manual glow-up ✨

okay bestie, welcome to the struct wcn36xx_sta(9) page 💅 this is the Kernel API Manual, and we're about to make it make sense. no cap.

---

✨ NAME ✨

struct wcn36xx_sta — literally the struct that holds all the STA related fields 🫶 like, that's its whole job, and it's doing amazing.

---

🦋 SYNOPSIS 🦋

here's the whole vibe, character for character, don't come for me:

struct wcn36xx_sta {
    struct list_head list;
    struct wcn36xx_vif *vif;
    u16 aid;
    u16 tid;
    u8 sta_index;
    u8 dpu_desc_index;
    u8 ucast_dpu_sign;
    u8 bss_sta_index;
    u8 bss_dpu_desc_index;
    bool is_data_encrypted;
    struct wcn36xx_hal_supported_rates_v1 supported_rates;
    spinlock_t ampdu_lock;
    enum wcn36xx_ampdu_state ampdu_state[16];
    int non_agg_frame_ct;
};

she's structured, she's organized, she's iconic 👑

🎀 Members 🎀

not me carefully going through every single one, because details matter bestie 💖

• tid — the traffic ID, used during AMPDU and in TX BD. two gigs, one field, main character energy fr fr.
• sta_index — the STA index, which the HW hands back to you after the config_sta call. it gets used in both the SMD channel and TX BD. slay.
• dpu_desc_index — the DPU descriptor index, also returned from HW after the config_sta call, and it's used in TX BD. periodt.
• bss_sta_index — the STA index returned from HW after the config_bss call, used in both the SMD channel and TX BD. khi. and bestie, peep the table below for when exactly it's used 👀
• bss_dpu_desc_index — the DPU descriptor index returned from HW after the config_bss call, and it's used in TX BD. simple, clean, no notes ✨

and here's that table, verbatim, because I would NEVER mess with the layout 🫶

                   ______________________________________________ |
                   |     STA     |       AP      |
                   |______________|_____________|_______________| |    TX BD
                   |bss_sta_index|   sta_index   |
                   |______________|_____________|_______________| |all SMD
calls |bss_sta_index|   sta_index   |
                   |______________|_____________|_______________|
                   |smd_delete_sta|  sta_index  |   sta_index   |
                   |______________|_____________|_______________|

quick vibe check 💀 the struct also carries list, vif, aid, ucast_dpu_sign, is_data_encrypted, supported_rates, ampdu_lock, ampdu_state[16], and non_agg_frame_ct — but the page itself only breaks down the members above, so I'm not out here making stuff up. iykyk.

and that's the whole page, bestie 💜 no crumbs left behind. this lil rewrite came from the source/version line ./drivers/net/wireless/ath/wcn..., dated October 2026, and it's still your girl struct wcn36xx_sta(9) the whole way through 🌸🎀💅
