💅 igc_read_phy_reg_mdic(9) — the Kernel API Manual moment 🎀

okay so bestie, welcome to igc_read_phy_reg_mdic, straight out of the Kernel API Manual — yes she's a section 9 girlie and she's here to read one (1) MDI control register for you. iconic behaviour, no notes ✨

---

🌸 NAME 🌸

igc_read_phy_reg_mdic — Read MDI control register 💖

---

🦋 SYNOPSIS 🦋

s32 igc_read_phy_reg_mdic (struct igc_hw *hw , u32 offset , u16 *data );

like literally that's the whole signature, she's not complicated, she just wants her three little parameters 🫶

---

✨ ARGUMENTS ✨

• hw — pointer to the HW structure 🌈 (the hardware bestie in question)
• offset — register offset to be read 🎯
• data — pointer to the read data 💫 (this is where the good stuff gets dropped off)

---

💜 DESCRIPTION 💜

Reads the MDI control register in the PHY at offset and stores the information read to data. that's it, that's the vibe — she goes to the PHY, she reads the MDI control register at whatever offset you handed her, and she drops the results into data. lowkey elegant. 🙈💅
