ENUM NL80211_SURVEY_INFO(9)

💅 enum nl80211_survey_info(9) — survey information ✨

okay so bestie, this is a page straight out of the kernel API manual (section 9, the kernel-api one) and it's literally the vibe check on your wifi radio's survey data 🦋. Yes, we're doing nl80211, yes it's a lot, no you're not allowed to leave, we're doing this together 💖

🎀 Constants 🎀

one bullet per constant, all the facts, all the slay 🫶

• __NL80211_SURVEY_INFO_INVALID — attribute number 0 is reserved (that's the "don't touch, it's the sentinel" slot 🙈)
• NL80211_SURVEY_INFO_FREQUENCY — center frequency of channel
• NL80211_SURVEY_INFO_NOISE — noise level of channel (u8, dBm) — yes the type and unit are staying, that's the law 💅
• NL80211_SURVEY_INFO_IN_USE — channel is currently being used
• NL80211_SURVEY_INFO_TIME — amount of time (in ms) that the radio was turned on (on channel or globally)
• NL80211_SURVEY_INFO_TIME_BUSY — amount of the time the primary channel was sensed busy (either due to activity or energy detect)
• NL80211_SURVEY_INFO_TIME_EXT_BUSY — amount of time the extension channel was sensed busy
• NL80211_SURVEY_INFO_TIME_RX — amount of time the radio spent receiving data (on channel or globally)
• NL80211_SURVEY_INFO_TIME_TX — amount of time the radio spent transmitting data (on channel or globally)
• NL80211_SURVEY_INFO_TIME_SCAN — time the radio spent for scan (on this channel or globally)
• NL80211_SURVEY_INFO_PAD — attribute used for padding for 64-bit alignment (the humble icon doing the invisible work 🧚)
• NL80211_SURVEY_INFO_TIME_BSS_RX — amount of time the radio spent receiving frames destined to the local BSS
• NL80211_SURVEY_INFO_FREQUENCY_OFFSET — center frequency offset in KHz
• __NL80211_SURVEY_INFO_AFTER_LAST — internal use (hands off, that's housekeeping business 💀)
• NL80211_SURVEY_INFO_MAX — highest survey info attribute number currently defined

💬 Description 💬

okay so here's the actual tea, bestie: these attribute types are used with NL80211_ATTR_SURVEY_INFO when getting information about a survey. that's it, that's the whole paragraph, but it's important, so don't skip it 😭
