ENUM ETHTOOL_MODULE_POWER_MODE_POLICY(9)

🌸 enum ethtool_module_power_mode_policy — the Kernel API Manual moment 💅

okay so bestie, this page is literally about a plug-in module's power mode policy — that's the name, no cap. it lives in the Kernel API Manual section, and it's honestly giving "small enum, big responsibilities" energy ✨

✨ SYNOPSIS ✨

enum ethtool_module_power_mode_policy {
    ETHTOOL_MODULE_POWER_MODE_POLICY_HIGH ,
    ETHTOOL_MODULE_POWER_MODE_POLICY_AUTO

};

that's it. two whole constants. she's compact, she's iconic, she ate 🎀

🦋 CONSTANTS 🦋

• ETHTOOL_MODULE_POWER_MODE_POLICY_HIGH — the module is always in high power mode. periodt. no sleeping, no napping, she's up and running 24/7 🔥
• ETHTOOL_MODULE_POWER_MODE_POLICY_AUTO — ok this one's the main character 👑 the host handles the transitions for you: it flips the module into high power mode when the first port using it is put administratively up, and drops it back to low power mode when the last port using it is put administratively down. so basically it matches your vibe — busy when you're busy, resting when literally everyone's gone 💤

lowkey the cutest part? it counts ports. last one out turns off the lights 🧚

okay that's the whole page, go be gorgeous with your power modes 💖 this cutie came out of ./include/uapi/linux in the Kernel API Manual, dated October 2026 — mwah, stan the kernel docs, bye bestie 🌸🎀🦋
