💅 igb_sgmii_uses_mdio_82575 — from the Kernel API Manual, bestie 🫶

okay so picture this: you're deep in kernel-land, snooping around this function called igb_sgmii_uses_mdio_82575, and you just need to know which way those I2C pins are leaning. That's literally the whole vibe of this page. Let's get into it 💖

✨ NAME ✨

igb_sgmii_uses_mdio_82575 — the function that tells you whether those I2C pins are out here doing external MDIO duty. No cap, that's its whole job 🌸

🦋 SYNOPSIS 🦋

bool igb_sgmii_uses_mdio_82575 (struct e1000_hw *hw );

like… that's it. one function. one pointer. one bool at the end. iconic 💅

🎀 ARGUMENTS 🎀

  • hw — pointer to the HW structure 🫶 that's the hardware struct, bestie, it's the thing you hand over so the function has something to look at.

🔥 DESCRIPTION 🔥

So this function gets called to figure out what the I2C pins are actually up to: are they being used for I2C, or are they moonlighting as an external MDIO interface? 👑

and here's the tea — the two options are mutually exclusive, meaning it's one or the other, never both at once. it's giving "pick a lane." so yeah, the function's whole raison d'être is answering that question. main character energy fr fr 🧚
