ENUM ETHTOOL_PSE_EVENT(9)

💖 NAME 💖

okay so bestie, this is the manual page for enum ethtool_pse_event(9) — the PSE event list for the PSE controller — and it lives in the Kernel API Manual. We are gonna go through every single constant, no skipping, no cap 💅✨

🦋 SYNOPSIS 🦋

Here’s the enum in all its glory, and yes, you’re gonna want to keep every member exactly as written:

enum ethtool_pse_event {
    ETHTOOL_PSE_EVENT_OVER_CURRENT ,
    ETHTOOL_PSE_EVENT_OVER_TEMP ,
    ETHTOOL_C33_PSE_EVENT_DETECTION ,
    ETHTOOL_C33_PSE_EVENT_CLASSIFICATION ,
    ETHTOOL_C33_PSE_EVENT_DISCONNECTION ,
    ETHTOOL_PSE_EVENT_OVER_BUDGET ,
    ETHTOOL_PSE_EVENT_SW_PW_CONTROL_ERROR

};

✨ Constants ✨

okay, these are the constants, and there are seven of them. Seven! Iconic little lineup fr fr 🎀

• ETHTOOL_PSE_EVENT_OVER_CURRENT — PSE output current is too high. like, too much current, bestie 😭🔥
• ETHTOOL_PSE_EVENT_OVER_TEMP — PSE is in an over temperature state. it’s giving “running hot” 🌡️💀
• ETHTOOL_C33_PSE_EVENT_DETECTION — detection process occur on the PSE. IEEE 802.3-2022 33.2.5 and 145.2.6 PSE detection of PDs. IEEE 802.3-202 30.9.1.1.5 aPSEPowerDetectionStatus ✨
• ETHTOOL_C33_PSE_EVENT_CLASSIFICATION — classification process occur on the PSE. IEEE 802.3-2022 33.2.6 and 145.2.8 classification of PDs mutual identification. IEEE 802.3-2022 30.9.1.1.8 aPSEPowerClassification. mutual identification slay 🫶
• ETHTOOL_C33_PSE_EVENT_DISCONNECTION — PD has been disconnected on the PSE. IEEE 802.3-2022 33.3.8 and 145.3.9 PD Maintain Power Signature. IEEE 802.3-2022 33.5.1.2.9 MPS Absent. IEEE 802.3-2022 30.9.1.1.20 aPSEMPSAbsentCounter. gone but not forgotten 😭👋
• ETHTOOL_PSE_EVENT_OVER_BUDGET — PSE turned off due to over budget situation. budget said no 💸🙈
• ETHTOOL_PSE_EVENT_SW_PW_CONTROL_ERROR — PSE faced an error managing the power control from software. software power-control said “not today” 💀⚡
