igb_read_phy_reg_i2c(9)

💖 igb_read_phy_reg_i2c(9) 💖

okay so bestie, this is the Kernel API Manual entry for igb_read_phy_reg_i2c(9). The way this function said “imma read a PHY register using i2c” and then stored the tea in data? iconic. 💅✨

🌸 NAME 🌸

igb_read_phy_reg_i2c — read PHY register using i2c 🦋

✨ SYNOPSIS ✨

s32 igb_read_phy_reg_i2c (struct e1000_hw *hw , u32 offset , u16 *data
);

🎀 ARGUMENTS 🎀

• hw — pointer to the HW structure. literally the hardware vibe. 🫶
• offset — register offset to be read. yes bestie, the exact spot. 🔥
• data — pointer to the read data. this is where the retrieved info gets parked. 💖

💫 DESCRIPTION 💫

Reads the PHY register at offset using the i2c interface and stores the retrieved information in data. no cap, that's the whole flow: i2c does its thing, the register gets read, and data gets the results. ✨
