🎀 Constants 🎀

• NL80211_FEATURE_SK_TX_STATUS — 💌 This driver supports reflecting back TX status to the socket error queue when requested with the socket option. It's giving "receipts, but for packets."
• NL80211_FEATURE_HT_IBSS — 🌸 This driver supports IBSS with HT datarates. Fancy mesh energy, slay.
• NL80211_FEATURE_INACTIVITY_TIMER — ⏰ This driver takes care of freeing up the connected inactive stations in AP mode. It's the cleanup bestie we all need.
• NL80211_FEATURE_CELL_BASE_REG_HINTS — 📡 This driver has been tested to work properly to support receiving regulatory hints from cellular base stations. Tested and trusted, no cap.
• NL80211_FEATURE_P2P_DEVICE_NEEDS_CHANNEL — 💀 (no longer available, only here to reserve the value for API/ABI compatibility) — so it's basically a historical icon, not a usable feature.
• NL80211_FEATURE_SAE — 🔐 This driver supports simultaneous authentication of equals (SAE) with user space SME (NL80211_CMD_AUTHENTICATE) in station mode. Secure handshake main character energy.
• NL80211_FEATURE_LOW_PRIORITY_SCAN — 🦋 This driver supports low priority scan. Scanning, but make it chill.
• NL80211_FEATURE_SCAN_FLUSH — 🧹 Scan flush is supported. Clean slate vibes.
• NL80211_FEATURE_AP_SCAN — 📶 Support scanning using an AP vif. AP mode said "I can scan too, actually."
• NL80211_FEATURE_VIF_TXPOWER — 🎚️ The driver supports per-vif TX power setting. Per-interface power control, we love to see it.
• NL80211_FEATURE_NEED_OBSS_SCAN — 👀 The driver expects userspace to perform OBSS scans and generate 20/40 BSS coex reports. This flag is used only for drivers implementing the CONNECT API; for AUTH/ASSOC it is implied. Big "you handle the scanning, I'll handle the connection" energy.
• NL80211_FEATURE_P2P_GO_CTWIN — 🪟 P2P GO implementation supports CT Window setting. Window management, but make it peer-to-peer.
• NL80211_FEATURE_P2P_GO_OPPPS — 😴 P2P GO implementation supports opportunistic powersave. Saving power when the moment is right.
• NL80211_FEATURE_ADVERTISE_CHAN_LIMITS — 📻 cfg80211 advertises channel limits (HT40, VHT 80/160 MHz) if this flag is set. It's giving "here are the bandwidth boundaries, bestie."
• NL80211_FEATURE_FULL_AP_CLIENT_STATE — 🫶 The driver supports full state transitions for AP clients. Without this flag (and if the driver doesn't have the AP SME in the device) the driver supports adding stations only when they're associated and adds them in associated state (to later be transitioned into authorized). With this flag they should be added before even sending the authentication reply and then transitioned into authenticated, associated and authorized states using station flags. Note that even for drivers that support this, the default is to add stations in authenticated/associated state, so to add unauthenticated stations the authenticated/associated bits have to be set in the mask. Lowkey a lot, but every detail matters. 💅
• NL80211_FEATURE_USERSPACE_MPM — 🧚 This driver supports a userspace Mesh Peering Management entity which may be implemented by registering for beacons or NL80211_CMD_NEW_PEER_CANDIDATE events. The mesh beacon is still generated by the driver. Userspace does the peering management, driver still handles the beacon.
• NL80211_FEATURE_ACTIVE_MONITOR — 🛰️ This driver supports an active monitor interface. An active monitor interface behaves like a normal monitor interface, but gets added to the driver. It ensures that incoming unicast packets directed at the configured interface address get ACKed. Monitor mode, but with extra accountability.
• NL80211_FEATURE_AP_MODE_CHAN_WIDTH_CHANGE — 🌈 This driver supports dynamic channel bandwidth change (e.g., HT 20 <-> 40 MHz channel) during the lifetime of a BSS. Bandwidth said "I contain multitudes."
• NL80211_FEATURE_DS_PARAM_SET_IE_IN_PROBES — 🎀 This device adds a DS Parameter Set IE to probe requests. Probe requests, but accessorized.
• NL80211_FEATURE_WFA_TPC_IE_IN_PROBES — 📨 This device adds a WFA TPC Report IE to probe requests. Another little IE moment.
• NL80211_FEATURE_QUIET — 🤫 This device, in client mode, supports Quiet Period requests sent to it by an AP. Client mode said "I can be quiet on command."
• NL80211_FEATURE_TX_POWER_INSERTION — 🔋 This device is capable of inserting the current tx power value into the TPC Report IE in the spectrum management TPC Report action frame, and in the Radio Measurement Link Measurement Report action frame. Power value insertion, very demure, very mindful.
• NL80211_FEATURE_ACKTO_ESTIMATION — ⏱️ This driver supports dynamic ACK timeout estimation (dynack). NL80211_ATTR_WIPHY_DYN_ACK flag attribute is used to enable dynack. Timeout estimation, but make it adaptive.
• NL80211_FEATURE_STATIC_SMPS — 🔌 Device supports static spatial multiplexing powersave, ie. can turn off all but one chain even on HT connections that should be using more chains. It's giving "one chain is enough, actually."
• NL80211_FEATURE_DYNAMIC_SMPS — ⚡ Device supports dynamic spatial multiplexing powersave, ie. can turn off all but one chain and then wake the rest up as required after, for example, rts/cts handshake. Sleepy chains that wake up when needed, iconic.
• NL80211_FEATURE_SUPPORTS_WMM_ADMISSION — 🍓 the device supports setting up WMM TSPEC sessions (TID aka TSID 0-7) with the NL80211_CMD_ADD_TX_TS command. Standard IEEE 802.11 TSPEC setup is not yet supported, it needs to be able to handle Block-Ack agreements and other things. So: WMM admission yes, full standard TSPEC setup not yet.
• NL80211_FEATURE_MAC_ON_CREATE — 🪪 Device supports configuring the vif's MAC address upon creation. See 'macaddr' field in the vif_params (cfg80211.h). Set the MAC at creation time, slay.
• NL80211_FEATURE_TDLS_CHANNEL_SWITCH — 🔀 Driver supports channel switching when operating as a TDLS peer. Channel switch, but peer-to-peer.
• NL80211_FEATURE_SCAN_RANDOM_MAC_ADDR — 🎭 This device/driver supports using a random MAC address during scan (if the device is unassociated); the NL80211_SCAN_FLAG_RANDOM_ADDR flag may be set for scans and the MAC address mask/value will be used. Privacy era.
• NL80211_FEATURE_SCHED_SCAN_RANDOM_MAC_ADDR — 🌀 This device/driver supports using a random MAC address for every scan iteration during scheduled scan (while not associated), the NL80211_SCAN_FLAG_RANDOM_ADDR may be set for scheduled scan and the MAC address mask/value will be used. Every iteration gets its own random-MAC moment.
• NL80211_FEATURE_ND_RANDOM_MAC_ADDR — 🌙 This device/driver supports using a random MAC address for every scan iteration during "net detect", i.e. scan in unassociated WoWLAN, the NL80211_SCAN_FLAG_RANDOM_ADDR may be set for scheduled scan and the MAC address mask/value will be used. Net detect scans said "random MAC for every iteration, periodt."
