🌸 struct iwl_tof_range_rsp_ap_entry_ntfy_v7(9) 🌸

okay so bestie, welcome to the Kernel API Manual — yes we're reading kernel docs together, this is our bonding era 💖 and this page is literally the whole rundown on one struct, so grab a lil snack and let's go ✨

💅 MEMBERS 💅

every single field, lovingly explained, main character energy each one:

• bssid — the BSSID of the AP 🎀 like, which AP is this even about.
• measure_status — the current AP's measurement status, one of enum iwl_tof_entry_status. that's the vibe check on how the measurement went 💀
• measure_bw — current AP bandwidth, and the mapping is 0 → 20MHz, 1 → 40MHz, 2 → 80MHz. slay, more hertz = more drama ✨
• rtt — The Round Trip Time that took for the last measurement for current AP [pSec]. picoseconds, because we're precise like that 💅
• rtt_variance — the variance of the RTT values measured for current AP. the chaotic-ness of the numbers, basically 🌪️
• rtt_spread — the difference between the max and the min RTT values measured for current AP in the current session [pSec].
• rssi — RSSI as uploaded in the Channel Estimation notification 📶
• rssi_spread — the difference between the max and the min RSSI values measured for current AP in the current session.
• last_burst — 1 if no more FTM sessions are scheduled for this responder. like when someone's last text was a final text 😭
• refusal_period — refusal period in case of IWL_TOF_ENTRY_RESPONDER_CANNOT_COLABORATE [sec]. yes it's spelled "COLABORATE", don't come for me, that's literally the identifier 🙈
• 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.
• rx_rate_n_flags — rate and flags of the last FTM frame received from this responder 📥
• tx_rate_n_flags — rate and flags of the last ack sent to this responder 📤
• t2t3_initiator — as calculated from the algo in the initiator.
• t1t4_responder — as calculated from the algo in the responder. matching set, we love a duo 🫶
• common_calib — Calib val that was used in for this AP measurement. (yes, "used in for" — I'm just the messenger bestie 🧚)
• 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 🔥
• rttConfidence — a value between 0 - 31 that represents the rtt accuracy. lowercase-sandwich naming, capital C in the middle, we don't question it, we respect it 👑
• reserved — for alignment. it's the padding, it's doing its little structural job, iconic 🌈
• 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. LE byte order on both, noted 💜

that's the whole page bestie, no skips, no shortcuts 💖

and for the lil sign-off: this one lives in the source tree at ./drivers/net/wireless/intel/i..., it's dated October 2026, and the footer stamp is literally struct iwl_...ntry_ntfy_v7(9) — the truncated-est little nameplate ever, we stan a legend 🎀✨🦋
