STRUCT IWL_TOF_RANGE_RSP_AP_ENTRY_NTFY(9)

🎀 struct iwl_tof_range_rsp_ap_entry_ntfy(9) 🎀

okay bestie, welcome to the Kernel API Manual ✨ this one's all about struct iwl_tof_range_rsp_ap_entry_ntfy and honestly? she's giving "receipts from the AP" energy 💅

🌸 NAME 🌸

struct iwl_tof_range_rsp_ap_entry_ntfy — AP parameters (response), periodt 💖

✨ SYNOPSIS ✨

like, here's her whole shape, no cap, copy it exactly:

🦋 Members 🦋

okay so every single field, one by one, let's go 🫶

• bssid — the BSSID of the AP 💫 literally just which AP we're talking about.
• measure_status — current AP's measurement status, one of enum iwl_tof_entry_status. bestie's mood ring, basically 🌈
• measure_bw — Current AP Bandwidth: 0 20MHz, 1 40MHz, 2 80MHz 📡 (yes those are the actual numbers, don't @ me)
• rtt — The Round Trip Time that took for the last measurement for current AP [pSec] ⏱️
• rtt_variance — The Variance of the RTT values measured for current AP. she's not consistent, and that's the tea 🙈
• rtt_spread — The Difference between the maximum and the minimum RTT values measured for current AP in the current session [pSec] 😭 the range of the chaos.
• rssi — RSSI as uploaded in the Channel Estimation notification 📶
• rssi_spread — The Difference between the maximum and the minimum RSSI values measured for current AP in the current session. same vibe check, but for signal 🔥
• last_burst — 1 if no more FTM sessions are scheduled for this responder 🏁 like, that's a wrap, we're done here.
• refusal_period — refusal period in case of IWL_TOF_ENTRY_RESPONDER_CANNOT_COLABORATE [sec] 💀 the AP said "not today" and this is how long they're on read.
• timestamp — The GP2 Clock [usec] where Channel Estimation notification was uploaded by the LMAC ⏰
• start_tsf — measurement start time in TSF of the mac specified in the range request 🕰️
• reserved1 — reserved, for backwards compatibility 🎀 (she's just sitting there so old code doesn't break, iconic behavior honestly)
• t2t3_initiator — as calculated from the algo in the initiator 🧮
• t1t4_responder — as calculated from the algo in the responder 🧮
• common_calib — Calib val that was used in for this AP measurement ✨ (yes, the wording is literally "used in for", we keep it, we don't fix it, we respect her)
• specific_calib — val that was used in for this AP measurement 🎯
• papd_calib_output — The result of the tof papd calibration that was injected into the algorithm. 💉 algorithm said "thank u for the data".
• rttConfidence — a value between 0 - 31 that represents the rtt accuracy 👑 lowkey how much you should trust her.
• reserved — for alignment 📐 (padding squads, always on duty)
• rx_pn — the last PN used for this responder Rx in case PMF is configured in LE byte order 🔐
• tx_pn — the last PN used for this responder Tx in case PMF is configured in LE byte order 🔐

ngl bestie, that's the whole page. every field, every unit, every "used in for" — nothing skipped, we ate and left no crumbs 🍓

mwah 💋 this came from ./drivers/net/wireless/intel/i... and it's dated October 2026, so like, see u in the future, and remember: struct iwl_tof_range_rsp_ap_entry_ntfy(9) forever 🌟
