STRUCT IWL_TOF_RANGE_REQ_AP_ENTRY_V6(9)

💅 struct iwl_tof_range_req_ap_entry_v6 — Kernel API Manual, bestie edition 🎀

okay so picture this: you're deep in the kernel API manual (yes, the Kernel API Manual, that's the manual name, we're folding it in here at the top like a lil name tag 🫶) and you hit this absolute icon of a struct. It's struct iwl_tof_range_req_ap_entry_v6 and it's literally the AP configuration parameters. That's it, that's the whole flex. Let's get into it ✨

🌸 SYNOPSIS 🌸

struct iwl_tof_range_req_ap_entry_v6 {
    __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;
    u8 sta_id;
    u8 cipher;
    u8 hltk[HLTK_11AZ_LEN];
    u8 tk[TK_11AZ_LEN];
    __le16 calib[IWL_TOF_BW_NUM];
    __le16 beacon_interval;
};

copy that exactly btw, every type, every array length, no cap 👑

✨ Members ✨

okay bestie, field-by-field tour, let's go 🦋

• initiator_ap_flags — see enum iwl_initiator_ap_flags. like, go look at it, it's the whole vibe check for what this AP entry is doing 💅
• channel_num — AP Channel number 📡
• format_bw — an enum iwl_location_format_bw, iykyk
• ctrl_ch_position — the coding of the control channel position relative to the center frequency, see iwl_mvm_get_ctrl_pos. yes the answer lives over there, go check it 🧚
• ftmr_max_retries — max number of retries to send the FTMR in case of no reply from the AP. like when you text them and they leave you on read, except the kernel tries again, iconic of it honestly 😭
• bssid — the AP's BSSID 🌈
• burst_period — recommended value to be sent to the AP. Measurement periodicity in units of 100ms. ignored if num_of_bursts_exp = 0 ⚠️ lowkey important, don't forget it
• samples_per_burst — the number of FTMs pairs in single Burst (1-31). note the range bestie, 1-31, stay in your lane 🔥
• 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) 📈
• sta_id — the station id of the AP. Only relevant when associated to the AP, otherwise should be set to IWL_INVALID_STA. yeah, set it right or don't set it at all 💀
• cipher — pairwise cipher suite for secured measurement. enum iwl_location_cipher. 🔐
• hltk — HLTK to be used for secured 11az measurement 🙈
• tk — TK to be used for secured 11az measurement 💜
• calib — an array of calibration values per FTM rx bandwidth. If IWL_INITIATOR_AP_FLAGS_USE_CALIB is set, the fw will use the calibration value that corresponds to the rx bandwidth of the FTM frame. so the firmware is matching values to bandwidths, main character energy fr fr ⭐
• beacon_interval — beacon interval of the AP in TUs. Only required if IWL_INITIATOR_AP_FLAGS_TB is set. only required required, got it? 🌸
