igb_write_phy_reg_mdic(9)

okay bestie, welcome to the igb_write_phy_reg_mdic(9) page from the Kernel API Manual 💖✨ it’s giving very specific kernel business and honestly? iconic.

🎀 NAME 🎀

igb_write_phy_reg_mdic — Write MDI control register

🌸 SYNOPSIS 🌸

s32 igb_write_phy_reg_mdic (struct e1000_hw *hw , u32 offset , u16 data
);

💖 ARGUMENTS 💖

• hw — pointer to the HW structure, iykyk 🫶
• offset — register offset to write to
• data — data to write to register at offset

✨ DESCRIPTION ✨

okay so the assignment here is literally one job, no extra drama: it writes data to the MDI control register in the PHY at offset. that’s the whole vibe check, and it ate 💅🔥
