phy_is_pseudo_fixed_link(9)

okay bestie, welcome to phy_is_pseudo_fixed_link(9) from the Kernel API Manual — yes, the whole manual-name moment is folded right in here like a cute little name tag 🫶✨

🌸 NAME 🌸

phy_is_pseudo_fixed_link is literally the convenience function for testing if this PHY is the CPU port facing side of an Ethernet switch, or similar. No cap, that’s the whole vibe check 💅

✨ SYNOPSIS ✨

bool phy_is_pseudo_fixed_link (struct phy_device *phydev );

🎀 ARGUMENTS 🎀

• phydev — the phy_device struct. That’s the bestie you hand over for the check 🦋
