ENUM ETHTOOL_PHYS_ID_STATE(9)

💖 enum ethtool_phys_id_state(9) 💖

okay so bestie, welcome to the Kernel API Manual — this one's all about enum ethtool_phys_id_state, which is genuinely just the ✨ indicator state for physical identification ✨. like, when you wanna make a network port physically blink so a human can find it in a rack. that's the whole vibe. iykyk 🎀

✨ NAME ✨

enum ethtool_phys_id_state — indicator state for physical identification 💅

---

🦋 SYNOPSIS 🦋

enum ethtool_phys_id_state {
    ETHTOOL_ID_INACTIVE ,
    ETHTOOL_ID_ACTIVE ,
    ETHTOOL_ID_ON ,
    ETHTOOL_ID_OFF

};

bestie look at that enum. four whole constants. no cap, that's it, that's the whole thing 🌸

---

👑 Constants 👑

• ETHTOOL_ID_INACTIVE — the physical ID indicator should be deactivated. it's giving "okay the light show is over, go home" 💀
• ETHTOOL_ID_ACTIVE — the physical ID indicator should be activated. main character moment for that LED fr fr 🔥
• ETHTOOL_ID_ON — the LED should be turned on. lowkey important caveat: this one is used iff ETHTOOL_ID_ACTIVE is not supported 🫶
• ETHTOOL_ID_OFF — the LED should be turned off. and same deal, babe: used iff ETHTOOL_ID_ACTIVE is not supported 🧚

ok that's genuinely everyone, i counted, don't come for me 😭

and that's the whole page bestie!! slay 🌟 this iconic little page lives at ./include/linux, dated October 2026, and it's enum ethtool_phys_id_state(9) through and through — catch you in the next manpage, mwah 💋💖
