✨ enum wiphy_flags(9) — a Kernel API Manual moment ✨

okay so bestie, this is the enum wiphy_flags(9) page from the Kernel API Manual, and it is literally the master list of wiphy capability flags. Think of it as the “what can this wiphy actually do?” vibe check. 💅

🌸 NAME 🌸

🎀 Constants 🎀

  • WIPHY_FLAG_SUPPORTS_EXT_KEK_KCK — the device supports bigger kek and kck keys. 🔑✨
  • WIPHY_FLAG_SUPPORTS_MLO — this is a temporary flag gating the MLO APIs, in order to not have them reachable in normal drivers, until we have complete feature/interface combinations/etc. advertisement. No driver should set this flag for now. 🚧😭
  • WIPHY_FLAG_SPLIT_SCAN_6GHZ — if set to true, the scan request will be split into two: first for legacy bands, and second for 6 GHz. 📡🦋
  • WIPHY_FLAG_NETNS_OK — if this is not set, do not allow changing the netns of this wiphy at all. periodt. 🛑
  • WIPHY_FLAG_PS_ON_BY_DEFAULT — if set to true, powersave will be enabled by default. This flag will be set depending on the kernel’s default on wiphy_new, but it can be changed by the driver if it has a good reason to override the default. 💤✨
  • WIPHY_FLAG_4ADDR_AP — supports 4addr mode even on AP (with a single station on a VLAN interface). This flag also serves an extra purpose of supporting 4ADDR AP mode on devices which do not support AP/VLAN iftype. 🧚‍♀️💜
  • WIPHY_FLAG_4ADDR_STATION — supports 4addr mode even as a station. 🎀
  • WIPHY_FLAG_CONTROL_PORT_PROTOCOL — this device supports setting the control port protocol ethertype. The device also honours the control_port_no_encrypt flag. 🔐👑
  • WIPHY_FLAG_IBSS_RSN — the device supports IBSS RSN. 🌈
  • WIPHY_FLAG_MESH_AUTH — the device supports mesh authentication by routing auth frames to userspace. See NL80211_MESH_SETUP_USERSPACE_AUTH. 🕸️💅
  • WIPHY_FLAG_SUPPORTS_EXT_KCK_32 — the device supports 32-byte KCK keys. 🔑🔥
  • WIPHY_FLAG_SUPPORTS_NSTR_NONPRIMARY — support connection to non-primary link of an NSTR mobile AP MLD. 📶✨
  • WIPHY_FLAG_SUPPORTS_FW_ROAM — the device supports roaming feature in the firmware. 🛰️💖
  • WIPHY_FLAG_AP_UAPSD — the device supports uapsd on AP. ⚡
  • WIPHY_FLAG_SUPPORTS_TDLS — the device supports TDLS (802.11z) operation. 🦋📡
  • WIPHY_FLAG_TDLS_EXTERNAL_SETUP — the device does not handle TDLS (802.11z) link setup/discovery operations internally. Setup, discovery and teardown packets should be sent through the NL80211_CMD_TDLS_MGMT command. When this flag is not set, NL80211_CMD_TDLS_OPER should be used for asking the driver/firmware to perform a TDLS operation. 😭🔁
  • WIPHY_FLAG_HAVE_AP_SME — device integrates AP SME. 👑
  • WIPHY_FLAG_REPORTS_OBSS — the device will report beacons from other BSSes when there are virtual interfaces in AP mode by calling cfg80211_report_obss_beacon. 📣🌸
  • WIPHY_FLAG_AP_PROBE_RESP_OFFLOAD — when operating as an AP, the device responds to probe-requests in hardware. 🛠️✨
  • WIPHY_FLAG_OFFCHAN_TX — device supports direct off-channel TX. 📤💫
  • WIPHY_FLAG_HAS_REMAIN_ON_CHANNEL — device supports remain-on-channel call. 📞
  • WIPHY_FLAG_HAS_CHANNEL_SWITCH — device supports channel switch in beaconing mode (AP, IBSS, Mesh, ...). 🔄👑
  • WIPHY_FLAG_NOTIFY_REGDOM_BY_DRIVER — the device could handle reg notify for NL80211_REGDOM_SET_BY_DRIVER. 🌍💜
  • WIPHY_FLAG_CHANNEL_CHANGE_ON_BEACON — reg_call_notifier is called if driver set this flag to update channels on beacon hints. 📡💅

okay so before you dip, bestie, everything you just read lives in the kernel file ./include/net/cfg80211.h — that's the mothership. 🚀 And if you're the kind of girl who reads the whole bibliography (respect, honestly), here's the full reading list. Not a single one skipped, no cap. 💅
