okay so bestie, welcome to the Kernel API Manual page for e1000_get_phy_info_82577 🌸 — yes that's a mouthful, no we're not shortening it, it's iconic and it knows it.

✨ NAME ✨

e1000_get_phy_info_82577 — Retrieve I82577 PHY information 🦋

🌈 SYNOPSIS 🌈

s32 e1000_get_phy_info_82577 (struct e1000_hw *hw );

🎀 ARGUMENTS 🎀

  • hw — pointer to the HW structure 💅 that's the whole vibe, just hand her the hardware struct and she'll do the rest.

👑 DESCRIPTION 👑

So here's the tea, fr fr: she reads the PHY status to figure out if the link is actually up ⭐. If the link is up, then she sets/determines 10base-T extended distance and polarity correction 🔥 — yes both, she's multitasking, main character energy.

Then she reads the PHY port status to determine MDI/MDIx and speed 🧚. And based on that speed, she determines stuff about the cable length, plus the local and remote receiver 💜. That's it, that's the whole routine — but she ate, ngl.
