ENUM NL80211_ATTR_CQM(9)

💖 NAME

okay so bestie, this is enum nl80211_attr_cqm — the connection quality monitor attributes, straight out of the Kernel API Manual (that's the enum nl80211_attr_cqm(9) page, hi, that's me 💅). It's the whole squad of attributes you use to keep tabs on how your wifi connection is vibing — signal strength, packet loss, transmit errors, all of it. ✨

🌸 Constants

like, every single one of them, in order, no skipping the boring ones 🫶

• __NL80211_ATTR_CQM_INVALID — the invalid one 🙈 that's literally it, her whole job is being invalid.
• NL80211_ATTR_CQM_RSSI_THOLD — the RSSI threshold in dBm. This is the level where, once your RSSI hits it, an event gets sent. Set it to zero to disable. ✨ and alternatively — if NL80211_EXT_FEATURE_CQM_RSSI_LIST is set — you can hand over multiple values as a low-to-high sorted array of threshold values in dBm, and events get sent when the RSSI value crosses any of those thresholds. iconique.
• NL80211_ATTR_CQM_RSSI_HYST — the RSSI hysteresis in dBm. This one's the chill pill 🧚: it's the minimum amount the RSSI level has to change after an event before a new event can even be issued — so it exists to reduce the effects of RSSI oscillation. not your signal flopping back and forth all dramatic.
• NL80211_ATTR_CQM_RSSI_THRESHOLD_EVENT — RSSI threshold event. yes bestie, an event, about the threshold. 🎀
• NL80211_ATTR_CQM_PKT_LOSS_EVENT — a u32 value indicating that this many consecutive packets were not acknowledged by the peer 😭
• NL80211_ATTR_CQM_TXE_RATE — TX error rate, in %. It's the minimum % of TX failures during the given NL80211_ATTR_CQM_TXE_INTVL before an NL80211_CMD_NOTIFY_CQM gets generated, with the reported NL80211_ATTR_CQM_TXE_RATE and NL80211_ATTR_CQM_TXE_PKTS. 🔥
• NL80211_ATTR_CQM_TXE_PKTS — the number of attempted packets in a given NL80211_ATTR_CQM_TXE_INTVL before NL80211_ATTR_CQM_TXE_RATE is checked. the pre-check count, basically.
• NL80211_ATTR_CQM_TXE_INTVL — the interval, in seconds. It specifies the periodic interval in which NL80211_ATTR_CQM_TXE_PKTS and NL80211_ATTR_CQM_TXE_RATE must be satisfied before generating an NL80211_CMD_NOTIFY_CQM. Set to 0 to turn off TX error reporting. 👑
• NL80211_ATTR_CQM_BEACON_LOSS_EVENT — a flag attribute that's set in a beacon loss event. 🦋
• NL80211_ATTR_CQM_RSSI_LEVEL — the RSSI value in dBm that triggered the RSSI threshold event. the little snitch that tells you what set it off 💀
• __NL80211_ATTR_CQM_AFTER_LAST — internal. that's the whole description. she's private, respect it 🙈
• NL80211_ATTR_CQM_MAX — highest key attribute. the ceiling, the final boss, the top of the list 🌈

ngl that's a lot of cross-references and every single one of them is here, exactly as listed — main character energy from the kernel docs fr fr 👑
