🎀 Constants 🎀

Vibe check on every single constant — this is literally the whole list, bestie, no skips:

  • BSS_CHANGED_ASSOC — association status changed (associated/disassociated), and lowkey that also implies a change in the AID too. 🫶
  • BSS_CHANGED_ERP_CTS_PROT — CTS protection changed.
  • BSS_CHANGED_ERP_PREAMBLE — preamble changed.
  • BSS_CHANGED_ERP_SLOT — slot timing changed.
  • BSS_CHANGED_HT — 802.11n parameters changed.
  • BSS_CHANGED_BASIC_RATES — Basic rateset changed.
  • BSS_CHANGED_BEACON_INT — Beacon interval changed.
  • BSS_CHANGED_BSSID — BSSID changed, for whatever reason (IBSS and managed mode).
  • BSS_CHANGED_BEACON — Beacon data changed, so retrieve the new beacon (beaconing modes).
  • BSS_CHANGED_BEACON_ENABLED — Beaconing should be enabled/disabled (beaconing modes).
  • BSS_CHANGED_CQM — Connection quality monitor config changed.
  • BSS_CHANGED_IBSS — IBSS join status changed.
  • BSS_CHANGED_ARP_FILTER — Hardware ARP filter address list or state changed.
  • BSS_CHANGED_QOS — QoS for this association was enabled/disabled. Note that it is only ever disabled for station mode. 👀
  • BSS_CHANGED_IDLE — Idle changed for this BSS/interface.
  • BSS_CHANGED_SSID — SSID changed for this BSS (AP and IBSS mode).
  • BSS_CHANGED_AP_PROBE_RESP — Probe Response changed for this BSS (AP mode).
  • BSS_CHANGED_PS — PS changed for this BSS (STA mode).
  • BSS_CHANGED_TXPOWER — TX power setting changed for this interface.
  • BSS_CHANGED_P2P_PS — P2P powersave settings (CTWindow, opportunistic PS) changed.
  • BSS_CHANGED_BEACON_INFO — Data from the AP's beacon became available: currently dtim_period only is under consideration.
  • BSS_CHANGED_BANDWIDTH — The bandwidth used by this interface changed. Note that this is only called when it changes after the channel context had been assigned.
  • BSS_CHANGED_OCB — OCB join status changed.
  • BSS_CHANGED_MU_GROUPS — VHT MU-MIMO group id or user position changed.
  • BSS_CHANGED_KEEP_ALIVE — keep alive options (idle period or protected keep alive) changed.
  • BSS_CHANGED_MCAST_RATE — Multicast Rate setting changed for this interface.
  • BSS_CHANGED_FTM_RESPONDER — fine timing measurement request responder functionality changed for this BSS (AP mode).
  • BSS_CHANGED_TWT — TWT status changed.
  • BSS_CHANGED_HE_OBSS_PD — OBSS Packet Detection status changed.
  • BSS_CHANGED_HE_BSS_COLOR — BSS Color has changed.
  • BSS_CHANGED_FILS_DISCOVERY — FILS discovery status changed.
  • BSS_CHANGED_UNSOL_BCAST_PROBE_RESP — Unsolicited broadcast probe response status changed.
  • BSS_CHANGED_MLD_VALID_LINKS — MLD valid links status changed.
  • BSS_CHANGED_MLD_TTLM — negotiated TID to link mapping was changed.
  • BSS_CHANGED_TPE — transmit power envelope changed.
  • BSS_CHANGED_NAN_LOCAL_SCHED — NAN local schedule changed (NAN mode only).
  • BSS_CHANGED_NPCA — NPCA parameters changed.

🌈 Description 🌈

These flags are used with the bss_info_changed, link_info_changed and vif_cfg_changed callbacks to indicate which parameter(s) changed. That's literally their whole job, bestie — they're the receipts that say which thing moved. 💖

okay bestie, the SEE ALSO section is literally the group chat of this man page 💖 — every single link is here, no skips, no cap. iykyk:

that's the entire squad 🫶 not me knowing every single one 💀
