ENUM NL80211_PEER_MEASUREMENT_FTM_CAPA(9)

📦 version 7.3.1, in nixpkgs unstable

🎀 ENUM NL80211_PEER_MEASUREMENT_FTM_CAPA(9) 🎀

okay bestie so this is a page from the Kernel API Manual — like, the actual kernel docs, not a vibe — and it's about enum nl80211_peer_measurement_ftm_capa. That's a whole mouthful, iykyk, but lowkey it's just a big list of "what can this Wi-Fi device actually do when it does FTM ranging" flags and attributes. Think of it as the device's little resume. 💅

✨ NAME ✨

enum nl80211_peer_measurement_ftm_capa — FTM capabilities. that's it, that's the whole name. short king. 👑

🦋 Constants 🦋

bestie. there are so many. buckle up, we're going through all of them, no skipping, I promise. 💖

  • __NL80211_PMSR_FTM_CAPA_ATTR_INVALID — invalid. that's literally it. the placeholder of the group. 💀
  • NL80211_PMSR_FTM_CAPA_ATTR_ASAP — flag attribute indicating ASAP mode is supported.
  • NL80211_PMSR_FTM_CAPA_ATTR_NON_ASAP — flag attribute indicating non-ASAP mode is supported.
  • NL80211_PMSR_FTM_CAPA_ATTR_REQ_LCI — flag attribute indicating if LCI data can be requested during the measurement.
  • NL80211_PMSR_FTM_CAPA_ATTR_REQ_CIVICLOC — flag attribute indicating if civic location data can be requested during the measurement.
  • NL80211_PMSR_FTM_CAPA_ATTR_PREAMBLES — u32 bitmap attribute of bits from enum nl80211_preamble.
  • NL80211_PMSR_FTM_CAPA_ATTR_BANDWIDTHS — bitmap of values from enum nl80211_chan_width indicating the supported channel bandwidths for FTM. ⚠️ note that a higher channel bandwidth may be configured to allow for other measurements types with different bandwidth requirement in the same measurement.
  • NL80211_PMSR_FTM_CAPA_ATTR_MAX_BURSTS_EXPONENT — u32 attribute indicating the maximum bursts exponent that can be used (if not present anything is valid).
  • NL80211_PMSR_FTM_CAPA_ATTR_MAX_FTMS_PER_BURST — u32 attribute indicating the maximum FTMs per burst (if not present anything is valid).
  • NL80211_PMSR_FTM_CAPA_ATTR_TRIGGER_BASED — flag attribute indicating if trigger based ranging measurement is supported.
  • NL80211_PMSR_FTM_CAPA_ATTR_NON_TRIGGER_BASED — flag attribute indicating if non-trigger-based ranging measurement is supported.
  • NL80211_PMSR_FTM_CAPA_ATTR_6GHZ_SUPPORT — flag attribute indicating if ranging on the 6 GHz band is supported. (6 GHz gang rise up 🌈)
  • NL80211_PMSR_FTM_CAPA_ATTR_MAX_TX_LTF_REP — u32 attribute indicating the maximum number of LTF repetitions the device can transmit in the preamble of the ranging NDP (zero means only one LTF, no repetitions).
  • NL80211_PMSR_FTM_CAPA_ATTR_MAX_RX_LTF_REP — u32 attribute indicating the maximum number of LTF repetitions the device can receive in the preamble of the ranging NDP (zero means only one LTF, no repetitions).
  • NL80211_PMSR_FTM_CAPA_ATTR_MAX_TX_STS — u32 attribute indicating the maximum number of space-time streams supported for ranging NDP TX (zero-based).

  • NL80211_PMSR_FTM_CAPA_ATTR_MAX_TOTAL_LTF_TX — u32 attribute indicating the maximum total number of LTFs the device can transmit. The total number of LTFs is (number of LTF repetitions) * (number of space-time streams). this limits the allowed combinations of LTF repetitions and STS.
  • NL80211_PMSR_FTM_CAPA_ATTR_MAX_TOTAL_LTF_RX — u32 attribute indicating the maximum total number of LTFs the device can receive. The total number of LTFs is (number of LTF repetitions) * (number of space-time streams). this limits the allowed combinations of LTF repetitions and STS. (yes it's the RX twin of the one above, they're matching, it's giving twin energy 👯)
  • NL80211_PMSR_FTM_CAPA_ATTR_RSTA_SUPPORT — flag attribute indicating the device supports operating as the RSTA in PMSR FTM request.
  • NL80211_PMSR_FTM_CAPA_ATTR_ISTA_CAPS — nested attribute containing ISTA (initiator) role capabilities. Uses the same sub-attributes as NL80211_PMSR_FTM_CAPA_ATTR_RSTA_CAPS.
  • NL80211_PMSR_FTM_CAPA_ATTR_RSTA_CAPS — nested attribute containing RSTA (responder) role capabilities.
  • NL80211_PMSR_FTM_CAPA_ATTR_SUPPORT_NTB — flag attribute (used inside NL80211_PMSR_FTM_CAPA_ATTR_ISTA_CAPS or NL80211_PMSR_FTM_CAPA_ATTR_RSTA_CAPS) indicating NTB ranging support.
  • NL80211_PMSR_FTM_CAPA_ATTR_SUPPORT_TB — flag attribute (used inside NL80211_PMSR_FTM_CAPA_ATTR_ISTA_CAPS or NL80211_PMSR_FTM_CAPA_ATTR_RSTA_CAPS) indicating TB ranging support.

(0 means unknown). applications can use this value to estimate the burst period to be given in the FTM request for the EDCA based ranging case. If non-zero, this value will be used to validate the burst period in the FTM request.
  • NL80211_PMSR_FTM_CAPA_ATTR_MIN_INTERVAL_NTB — u32 attribute indicating the minimum NTB ranging interval supported by the device in milli seconds. (0 means unknown). applications can use this value to estimate the burst period to be given in the FTM request for the NTB ranging case. If non-zero, this value will be used to validate the nominal time in the FTM request. 🕰️
  • NL80211_PMSR_FTM_CAPA_ATTR_PD_PREAMBLES — u32 bitmap of values from enum nl80211_preamble indicating the supported preambles for PD ranging requests. ⚠️ only valid if NL80211_PMSR_FTM_TYPE_CAPA_ATTR_PD_SUPPORT is set.
  • NL80211_PMSR_FTM_CAPA_ATTR_PD_BANDWIDTHS — u32 bitmap of values from enum nl80211_chan_width indicating the supported channel bandwidths for PD ranging requests. ⚠️ only valid if NL80211_PMSR_FTM_TYPE_CAPA_ATTR_PD_SUPPORT is set.
  • NUM_NL80211_PMSR_FTM_CAPA_ATTR — internal. 🤫 (not for you, it's for the kernel, move along)
  • NL80211_PMSR_FTM_CAPA_ATTR_MAX — highest attribute number. the ceiling. the final boss. 👑

aaaand that's the full attribute lineup — every single one accounted for, nothing dropped, nothing renamed, nothing merged. ✨

ok that was a whole journey 😭 but you made it, bestie. that's the entire friend group — go click through them and slay your kernel networking arc 💅✨

and hey, before you close the tab: this lil page came from ./include/uapi/linux, dated October 2026, and it's titled enum nl80211...ent_ftm_capa(9) — like, that's the source, the version, and the date, all bundled up 🫶 periodt, see you in the next manpage 👑💜
