💖 phy_interface_is_rgmii(9) 💖

okay bestie, welcome to your Kernel API Manual moment for phy_interface_is_rgmii(9). this is the page for a convenience function that tests if a PHY interface is RGMII — all variants, not just one. it's giving tiny helper with main character energy, fr fr. 🦋✨

🌸 NAME 🌸

phy_interface_is_rgmii — convenience function for testing if a PHY interface is RGMII (all variants). lowkey iconic name, highkey does exactly what it says 💅

🎀 SYNOPSIS 🎀

bool phy_interface_is_rgmii (struct phy_device *phydev );

🫶 ARGUMENTS 🫶

• phydev — the phy_device struct. that's the struct we're passing in, bestie 🫶
