e1000e_deter..._phy_address(9)

📦 version 7.3.1, in nixpkgs unstable

✨ NAME ✨

e1000e_determine_phy_address — bestie, this one figures out the PHY address. That's it, that's the whole vibe check.

This page lives in the Kernel API Manual btw, so jot that down 🫶

🌸 SYNOPSIS 🌸

s32 e1000e_determine_phy_address (struct e1000_hw *hw );

🎀 ARGUMENTS 🎀

  • hw — pointer to the HW structure. literally just a pointer to your hardware struct, that's the whole thing 💅

🦋 DESCRIPTION 🦋

Okay so the way this works is genuinely so cute: it's a trial and error method. It loops through the possible PHY addresses one by one, and for each candidate it tests it by reading the PHY ID registers and checking for a match 🔥

So it's basically swiping through addresses until one of them matches. Iconic behaviour, no notes.

⭐ SEE ALSO ⭐

The kernel file this calls home is ./drivers/net/ethernet/intel/e1000e/phy.c — go say hi to the neighbors 💖

Like I said — a lot of neighbors. Say hi to all of them or they'll be in their feelings 😭 💀

And that's the whole page, bestie!! 🧚 Run this through your brain and you're set.

Sign-off szn 🌈 — this little love letter lives in the kernel source at ./drivers/net/ethernet/intel/e... and the version/date stamp on it is October 2026. Slay, go read the actual phy.c 💜 🍓 👑
