🎀 Constants 🎀

like, the full roster, no skips, iykyk 💅

• HWSIM_ATTR_UNSPEC — the unspecified attribute, there purely to catch errors 👀
• HWSIM_ATTR_ADDR_RECEIVER — MAC address of the radio device that the frame is broadcasted to 📡
• HWSIM_ATTR_ADDR_TRANSMITTER — MAC address of the radio device that the frame was broadcasted from 🛰️
• HWSIM_ATTR_FRAME — a Data array, literally just data 🍓
• HWSIM_ATTR_FLAGS — mac80211 transmission flags, used to process properly the frame at user space 🚩
• HWSIM_ATTR_RX_RATE — estimated rx rate index for this frame at user space 📶
• HWSIM_ATTR_SIGNAL — estimated RX signal for this frame at user space 📈
• HWSIM_ATTR_TX_INFO — an ieee80211_tx_rate array 🌈
• HWSIM_ATTR_COOKIE — sk_buff cookie to identify the frame 🍪
• HWSIM_ATTR_CHANNELS — a u32 attribute used with the HWSIM_CMD_NEW_RADIO command, giving the number of channels supported by the new radio 📻
• HWSIM_ATTR_RADIO_ID — a u32 attribute used with HWSIM_CMD_DESTROY_RADIO only, to destroy a radio 💀
• HWSIM_ATTR_REG_HINT_ALPHA2 — alpha2 for regulatory driver hint (nla string, length 2) 🌍
• HWSIM_ATTR_REG_CUSTOM_REG — custom regulatory domain index (u32 attribute) 🗺️
• HWSIM_ATTR_REG_STRICT_REG — requests REGULATORY_STRICT_REG (flag attribute) 🚨
• HWSIM_ATTR_SUPPORT_P2P_DEVICE — support P2P Device virtual interface (flag) 🫶
• HWSIM_ATTR_USE_CHANCTX — used with the HWSIM_CMD_NEW_RADIO command to force use of channel contexts even when only a single channel is supported 🔒
• HWSIM_ATTR_DESTROY_RADIO_ON_CLOSE — used with the HWSIM_CMD_NEW_RADIO command to force radio removal when the process that created the radio dies 😭
• HWSIM_ATTR_RADIO_NAME — Name of radio, e.g. phy666 👑
• HWSIM_ATTR_NO_VIF — Do not create vif (wlanX) when creating radio. 🙈
• HWSIM_ATTR_FREQ — Frequency at which packet is transmitted or received. 📡
• HWSIM_ATTR_PAD — padding attribute for 64-bit values, ignore 🧚
• HWSIM_ATTR_TX_INFO_FLAGS — additional flags for corresponding rates of HWSIM_ATTR_TX_INFO 🏴
• HWSIM_ATTR_PERM_ADDR — permanent mac address of new radio 🪪
• HWSIM_ATTR_IFTYPE_SUPPORT — u32 attribute of supported interface types bits 🔢
• HWSIM_ATTR_CIPHER_SUPPORT — u32 array of supported cipher types 🔐
• HWSIM_ATTR_MLO_SUPPORT — claim MLO support (exact parameters TBD) for the new radio 🧪
• HWSIM_ATTR_PMSR_SUPPORT — nested attribute used with HWSIM_CMD_NEW_RADIO to provide peer measurement capabilities. (nl80211_peer_measurement_attrs) 📐
• HWSIM_ATTR_PMSR_REQUEST — nested attribute used with HWSIM_CMD_START_PMSR to provide details about peer measurement request (nl80211_peer_measurement_attrs) 📨
• HWSIM_ATTR_PMSR_RESULT — nested attributed used with HWSIM_CMD_REPORT_PMSR to provide peer measurement result (nl80211_peer_measurement_attrs) 📊
• HWSIM_ATTR_MULTI_RADIO — Register multiple wiphy radios (flag). Adds one radio for each band. Number of supported channels will be set for each radio instead of for the wiphy. 🎚️
• HWSIM_ATTR_SUPPORT_NAN_DEVICE — support NAN Device virtual interface (flag) 🦋
• HWSIM_ATTR_SUPPORT_BACKGROUND_RADAR — background radar/CAC support (flag) 🔥
• __HWSIM_ATTR_MAX — enum limit, the final boss 🏁

bestie this is kernel source territory — go read the actual header before you go poking at radios, k? 🫶
