igb_read_phy_reg_mdic(9)

💖 NAME 💖

okay so welcome to the igb_read_phy_reg_mdic(9) page from the Kernel API Manual — yes bestie, that’s the manual name, folded in up top like a little name tag 🎀. This function is literally Read MDI control register: igb_read_phy_reg_mdic — Read MDI control register.

✨ SYNOPSIS ✨

the signature is giving exactly this, no edits, no cap:

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

🎀 ARGUMENTS 🎀

• hw — pointer to the HW structure 💖
• offset — register offset to be read ✨
• data — pointer to the read data 🎀

🌸 DESCRIPTION 🌸

okay so the actual tea: it reads the MDI control register in the PHY at offset, and stores the information read to data. that’s the whole plot, and it ate. 💅✨
