e1000e_check_for_fiber_link(9)

📦 version 7.3.1, in nixpkgs unstable

Okay so this is a page straight out of the Kernel API Manual, and it's about one tiny function that does one tiny job in the Intel e1000e driver. Fiber link check. That's it. That's the whole vibe. 🌸

✨ NAME ✨

e1000e_check_for_fiber_link — check for link, but make it Fiber 🧚

🎀 SYNOPSIS 🎀

s32 e1000e_check_for_fiber_link (struct e1000_hw *hw );

Yeah. That's the whole signature. s32 in, s32 out, one pointer in the middle. Slay. 💅

🦋 ARGUMENTS 🦋

  • hw — pointer to the HW structure. That's the hardware struct, the main character of this whole driver. You hand it over, it does the link-checking thing. Periodt. 👑

🌈 DESCRIPTION 🌈

So basically this function checks whether the link is up on the hardware. That's the mission. 🫶

And here's the lil twist: if the link is not up and we've got a signal, then we need to force the link up. Not me being dramatic — that's literally what the manpage says. Signal present but no link? Force it. 💀

🔥 SEE ALSO 🔥

Bestie, buckle up, because this page's SEE ALSO section is not playing around. It's giving "everyone in the driver showed up to the party." 🎉

First off, the kernel file we're living in:

  • Kernel file ./drivers/net/ethernet/intel/e1000e/mac.c

And now the whole friend group, in exactly the order the page lists them:

Look at that list. Thirty-nine deep. That's not a SEE ALSO, that's a whole group chat. 💜

🍓 the cute sign-off 🍓

This page came from ./drivers/net/ethernet/intel/e1000e/... (yes, the path got cut off at the edge of the page, tragic, we don't know the rest) and it's dated October 2026 — future vibes only, ngl. Anyway, go force that link up. Iykyk. 😭✨🎀
