💅 e1000_set_d3_lplu_state_ich8lan(9)

okay so bestie, welcome to the Kernel API Manual</> ✨ this one's a little PHY-flavoured gem from the e1000e driver and honestly it's giving "quietly important" energy. sit down, hydrate, let's go 🫶

🌸 NAME 🌸

e1000_set_d3_lplu_state_ich8lan — Set Low Power Linkup D3 state 💤

✨ SYNOPSIS ✨

s32 e1000_set_d3_lplu_state_ich8lan (struct e1000_hw *hw , bool active
);

like yes that's the whole signature, no cap 💅

🎀 ARGUMENTS 🎀

  • hw — pointer to the HW structure. the main character of the whole driver, fr fr 👑
  • active — true to enable LPLU, false to disable. that's the vibe switch, bestie 🦋

🦋 DESCRIPTION 🦋

So what does it actually do? It sets the LPLU D3 state according to the active flag 🎯

And here's the cute little two-for-one deal: when it's activating LPLU, this function also disables smart speed — and vice versa. so whichever one you turn on, the other one gets turned off. they do not coexist, periodt 💀

lowkey important caveat:</> LPLU will not be activated unless the device autonegotiation advertisement meets standards of either 10 or 10/100 or 10/100/1000 at all duplexes. so if your advertisement isn't up to spec, bestie, nothing happens. it's a no 💅

Also — and this is the iykyk part — this is a function pointer entry point only, called by PHY setup routines. don't be out here calling it randomly, it's not for you 🙈

🔥 SEE ALSO 🔥

first up, the source file itself, in all its glory:

  • Kernel file ./drivers/net/ethernet/intel/e1000e/ich8lan.c 👑

and then the whole extended friend group — every one of these is a sibling reference, and no, we are not skipping any of them, that would be rude:

like… that's the whole squad 😭 go read them, they're iconic 🧚

quick vibe check bestie:</> this page ships from ./drivers/net/ethernet/intel/e... and it's dated October 2026. that's the source path (shortened with an ellipsis in the footer) and the version date, so if you're citing it, that's your receipt 🧾✨

and that's the whole page! tysm for reading, mwah 💖🎀🦋
