ENUM EF4_PHY_MODE(9)

enum ef4_phy_mode(9) 🦋✨

okay so bestie, this is the Kernel API Manual entry for enum ef4_phy_mode, and it's literally all about PHY operating mode flags. short bop, no cap.

🌸 NAME 🌸

enum ef4_phy_mode — PHY operating mode flags. that's the name, that's the vibe, iconic.

🎀 SYNOPSIS 🎀

the whole enum lineup, exactly as it appears:

       enum ef4_phy_mode {
           PHY_MODE_NORMAL ,
           PHY_MODE_TX_DISABLED ,
           PHY_MODE_LOW_POWER ,
           PHY_MODE_OFF ,
           PHY_MODE_SPECIAL

       };

🎀 Constants 🎀

these are the mode constants, bestie — each one is a whole mood:

• PHY_MODE_NORMAL — it's on and should pass traffic. main character energy, fr fr. ✅
• PHY_MODE_TX_DISABLED — on, but with TX disabled. 💅
• PHY_MODE_LOW_POWER — set to low power through MDIO. 🔋
• PHY_MODE_OFF — switched off through external control. 🌙
• PHY_MODE_SPECIAL — on, but it will not pass traffic. 🚫
