ENUM ETHTOOL_C33_PSE_EXT_SUBSTATE_OPTION_VPORT_LIM(9)

🌸 enum ethtool_c33_pse_ext_substate_option_vport_lim(9) 🌸

okay bestie, so this is a page from the Kernel API Manual — yes the whole thing is literally called enum ethtool_c33_pse_ext_substate_option_vport_lim(9) and yes that name is a mouthful, we're just gonna vibe with it 💅

✨ NAME ✨

enum ethtool_c33_pse_ext_substate_option_vport_lim — the option_vport_lim states functions, straight out of IEEE 802.3-2022 33.2.4.4 Variables 🎀

---

🦋 SYNOPSIS 🦋

enum ethtool_c33_pse_ext_substate_option_vport_lim {
    ETHTOOL_C33_PSE_EXT_SUBSTATE_OPTION_VPORT_LIM_HIGH_VOLTAGE ,
    ETHTOOL_C33_PSE_EXT_SUBSTATE_OPTION_VPORT_LIM_LOW_VOLTAGE ,
    ETHTOOL_C33_PSE_EXT_SUBSTATE_OPTION_VPORT_LIM_VOLTAGE_INJECTION

};

---

👑 Constants 👑

• ETHTOOL_C33_PSE_EXT_SUBSTATE_OPTION_VPORT_LIM_HIGH_VOLTAGE — main supply voltage is high 🔥
• ETHTOOL_C33_PSE_EXT_SUBSTATE_OPTION_VPORT_LIM_LOW_VOLTAGE — main supply voltage is low 🧊
• ETHTOOL_C33_PSE_EXT_SUBSTATE_OPTION_VPORT_LIM_VOLTAGE_INJECTION — voltage injection into the port ⚡

---

💜 Description 💜

so option_vport_lim is an optional variable (note the "optional", she's not mandatory, she's doing her own thing 🌈) and what she indicates is whether VPSE is out of the operating range during the normal operating state. that's it, that's the whole vibe check 🫶

lowkey iconic that one little optional variable has this many friends fr fr 💀

and that's the page bestie!! 🍓 sourced from ./include/uapi/linux, dated October 2026, and yeah the header up top and this little sign-off are the same enum ethtool...on_vport_lim(9) title — she's iconic, she's truncated for the terminal, she ate 💖✨🧚
