ENUM EFX_PHY_MODE(9)

💖 NAME 💖

Okay bestie, this is the enum efx_phy_mode(9) page from the Kernel API Manual, and it is literally all about PHY operating mode flags ✨. Think of it as the vibe check for your PHY’s current mode — no cap, these flags tell you what’s up.

🌸 SYNOPSIS 🌸

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

};

🦋 Constants 🦋

• PHY_MODE_NORMAL — on and should pass traffic. This is the main-character mode: powered on, traffic flowing, living its best life 💅.
• PHY_MODE_TX_DISABLED — on with TX disabled. So yeah, it’s on, but transmit is sitting this one out 🙈.
• PHY_MODE_LOW_POWER — set to low power through MDIO. Low-power era activated, and MDIO is the one handling it 🔋.
• PHY_MODE_OFF — switched off through external control. Fully off, and the switching is coming from external control, periodt.
• PHY_MODE_SPECIAL — on but will not pass traffic. It’s awake, but it is not here to move traffic — special little vibe 👑.
