ENUM ETHTOOL_C33_PSE_PW_D_STATUS(9)

📦 version 7.3.1, in nixpkgs unstable

✨ enum ethtool_c33_pse_pw_d_status(9) ✨

okay bestie, welcome to the Kernel API Manual 🫶 this one is a little enum that answers the question every PSE girlie is dying to know: what is the power detection status rn? 💅

💖 NAME 💖

enum ethtool_c33_pse_pw_d_status — the power detection status of the PSE, fr fr. it's straight outta IEEE 802.3-2022 30.9.1.1.3 aPoDLPSEPowerDetectionStatus. yes that's a real citation, no cap, go look it up iykyk 📖✨

🌸 SYNOPSIS 🌸

enum ethtool_c33_pse_pw_d_status {
    ETHTOOL_C33_PSE_PW_D_STATUS_UNKNOWN ,
    ETHTOOL_C33_PSE_PW_D_STATUS_DISABLED ,
    ETHTOOL_C33_PSE_PW_D_STATUS_SEARCHING ,
    ETHTOOL_C33_PSE_PW_D_STATUS_DELIVERING ,
    ETHTOOL_C33_PSE_PW_D_STATUS_TEST ,
    ETHTOOL_C33_PSE_PW_D_STATUS_FAULT ,
    ETHTOOL_C33_PSE_PW_D_STATUS_OTHERFAULT

};

like. look at her. seven constants, all in a row, all shorthanded without the = values. main character energy honestly 👑

🎀 Constants 🎀

okay so each one of these is a mood, let's go through the whole roster 💅

  • ETHTOOL_C33_PSE_PW_D_STATUS_UNKNOWN — PSE status is unknown. that's it. that's the vibe. we literally do not know 😭 she's a mystery, an enigma, a blank slate.
  • ETHTOOL_C33_PSE_PW_D_STATUS_DISABLED — the enumeration "disabled" indicates that the PSE State diagram is in the state DISABLED. so she's turned off, resting, not doing power things. respect her downtime 💤
  • ETHTOOL_C33_PSE_PW_D_STATUS_SEARCHING — the enumeration "searching" indicates the PSE State diagram is in a state other than those listed. yes, she's the catch-all bestie — if it's not one of the others, congrats, it's this one 🌈
  • ETHTOOL_C33_PSE_PW_D_STATUS_DELIVERING — the enumeration "deliveringPower" indicates that the PSE State diagram is in the state POWER_ON. she's delivering!! she's serving!! power is flowing and we love her for it ⚡🔥
  • ETHTOOL_C33_PSE_PW_D_STATUS_TEST — the enumeration "test" indicates that the PSE State diagram is in the state TEST_MODE. experimental era 🧪✨
  • ETHTOOL_C33_PSE_PW_D_STATUS_FAULT — the enumeration "fault" indicates that the PSE State diagram is in the state TEST_ERROR. something went wrong in testing 😬 she's not okay and that's valid.
  • ETHTOOL_C33_PSE_PW_D_STATUS_OTHERFAULT — the enumeration "otherFault" indicates that the PSE State diagram is in the state IDLE due to the variable error_condition = true. so she's chilling in IDLE, but specifically because error_condition = true, not just vibing 💀 yes there's a difference and yes you need to know it.
🫶 quick reality check bestie: SEARCHING is the fallback for "a state other than those listed" — not a fancy named state of its own. that's the spec's words, not mine!
