okay so bestie, welcome to the Kernel API Manual entry for igb_read_xmdio_reg 🫶 this one's short and sweet, no cap.

🌸 NAME 🌸

igb_read_xmdio_reg — literally just: read an XMDIO register 👑 that's the whole vibe.

---

✨ SYNOPSIS ✨

s32 igb_read_xmdio_reg (struct e1000_hw *hw , u16 addr , u8 dev_addr ,
       u16 *data );

like, that's the signature, don't @ me 💅

---

🎀 ARGUMENTS 🎀

• hw — pointer to the HW structure 💖 your main character, the hardware itself.
• addr — the XMDIO address to program 🦋
• dev_addr — the device address to program 🌸
• data — the value to be read from the EMI address ⭐ (yes, it's a pointer, she writes back into it, iykyk)
