phy_set_bits(9)

💖 phy_set_bits(9) — Kernel API Manual, bestie edition 💖

🌸 NAME 🌸

okay so phy_set_bits is literally the convenience function for setting bits in a PHY register. that's the whole assignment, no cap 💅

✨ SYNOPSIS ✨

int phy_set_bits (struct phy_device *phydev , u32 regnum , u16 val );

🎀 ARGUMENTS 🎀

• phydev — the phy_device struct. that's the main-character struct bestie 🫶
• regnum — register number to write. yes, the actual register number, write it down ✍️
• val — bits to set. the bits!!! the little guys getting set!!! 🔥
