igb_get_phy_info_m88(9)

💖 NAME 💖

okay bestie, meet igb_get_phy_info_m88 from the Kernel API Manual — this is the function that retrieves PHY information. That's the whole vibe. ✨

🎀 SYNOPSIS 🎀

s32 igb_get_phy_info_m88 (struct e1000_hw *hw );

🌸 ARGUMENTS 🌸

• hw — pointer to the HW structure 🫶

🦋 DESCRIPTION 🦋

Valid for only copper links, bestie — copper only, no cap. 🧚

It reads the PHY status register (sticky read) to verify that link is up. Then it reads the PHY special control register to determine the polarity and 10base-T extended distance. Then it reads the PHY special status register to determine MDI/MDIx and current speed. If speed is 1000, then it determines cable length, local and remote receiver. 👑
