STRUCT IWL_TOF_RANGE_REQ_AP_ENTRY_V4(9)

💖 struct iwl_t_tof_range_req_ap_entry_v4(9) 💖

okay so bestie, welcome to the Kernel API Manual ✨ — this one lives in section 9 of the kernel docs, and it's literally the <struct iwl_tof_range_req_ap_entry_v4> situation. it's giving "AP configuration parameters" and honestly? she ate. 🎀

---

🌸 NAME 🌸

struct iwl_tof_range_req_ap_entry_v4 — AP configuration parameters. that's it, that's the whole vibe. no cap. 💅

---

✨ SYNOPSIS ✨

here's the whole glow-up, copy it exactly, she's iconic:

struct iwl_tof_range_req_ap_entry_v4 {
    __le32 initiator_ap_flags;
    u8 channel_num;
    u8 format_bw;
    u8 ctrl_ch_position;
    u8 ftmr_max_retries;
    u8 bssid[ETH_ALEN];
    __le16 burst_period;
    u8 samples_per_burst;
    u8 num_of_bursts;
    __le16 reserved;
    u8 hltk[HLTK_11AZ_LEN];
    u8 tk[TK_11AZ_LEN];
 };

like... look at her. every field accounted for. not one missing. we love a complete struct. 🫶

🦋 Members 🦋

okay bestie, field-by-field tour, let's go 🧚:

• initiator_ap_flags — see enum iwl_initiator_ap_flags. that's where the actual flag lore lives, go read it iykyk.
• channel_num — the AP Channel number. simple. slay.
• format_bw — enum iwl_location_format_bw. yes, the enum name is very close to other enum names, do not get it twisted 💀.
• ctrl_ch_position — the coding of the control channel position relative to the center frequency, see iwl_mvm_get_ctrl_pos. (not me being obsessed with how specific that is 😭)
• ftmr_max_retries — max number of retries to send the FTMR in case of no reply from the AP. like, how many times do we knock before we accept nobody's home.
• bssid — the AP's BSSID. main character identifier energy 👑.
• burst_period — recommended value to be sent to the AP. measurement periodicity in units of 100ms. ignored if num_of_bursts_exp = 0 — yes, really, it just gets ignored, so don't come for her.
• samples_per_burst — the number of FTMs pairs in single Burst (1-31). range check your girl bestie, fr fr.
• num_of_bursts — recommended value to be sent to the AP. 2s exponent of the number of measurement iterations (min 2^0 = 1, max 2^14). math is mathing 🌈.
• reserved — for alignment and future use. she's just holding space, literally. 🙈
• hltk — HLTK to be used for secured 11az measurement. 🔥
• tk — TK to be used for secured 11az measurement. yes there are two, and yes both matter. 💜
