e1000_smartspeed(9)

💅 e1000_smartspeed(9) — from the Kernel API Manual 🎀

okay so first things first, bestie: this page lives in the Kernel API Manual, and the function we're hyping up is e1000_smartspeed. Yes it's a whole man page for one little function. Iconic behaviour honestly.

✨ NAME ✨

e1000_smartspeed — Workaround for SmartSpeed on 82541 and 82547 controllers.

That's it. That's the whole pitch. A workaround, for SmartSpeed, on the 82541 and 82547 controllers specifically. Not all of them, not some of them — those two. Read the part numbers, memorize the part numbers, respect the part numbers 💅

---

🌸 SYNOPSIS 🌸

void e1000_smartspeed (struct e1000_adapter *adapter );

Notice the void? Yeah. She takes one argument and she gives you nothing back. No return value, no output, no little "here's your result" gift basket. She just goes in and does the thing. Main character energy fr fr 🫶

---

🦋 ARGUMENTS 🦋

• adapter — address of board private structure.

That's your one (1) job as the caller: hand over the address of the board private structure. Not the structure itself, bestie, the address. Pointer energy only ✨

Lowkey a mood that the entire DESCRIPTION section is one sentence, and that sentence is just "it's a workaround." No cap, some pages give you paragraphs, this one gives you vibes and a part number. Read it, run it, move on 🧚

🍓 sign-off 🍓

Big thank you to the source she's filed under — ./drivers/net/ethernet/intel/e... — and a very happy October 2026 to you and yours 🎀 and yeah, the page signs itself e1000_smartspeed(9) at the bottom too, because she's consistent like that. Periodt. 💜
