e1000e_setup_copper_link(9)

📦 version 7.3.1, in nixpkgs unstable

okay so this is a page from the Kernel API Manual, and bestie, it's literally the glow-up routine for your copper link. sit down, hydrate, let's go 💅

🌸 NAME 🌸

e1000e_setup_copper_link — configure copper link settings. that's it, that's the vibe check 🦋

🎀 SYNOPSIS 🎀

s32 e1000e_setup_copper_link (struct e1000_hw *hw );

💖 ARGUMENTS 💖

  • hw — pointer to the HW structure. yeah, that one. the main character 🫶

⭐ DESCRIPTION ⭐

so here's the tea 🍓: this function calls the appropriate function to configure the link for auto-neg or forced speed and duplex. pick your fighter, it handles both.

then we check for link. and like — once the link is established, calls to configure collision distance and flow control get called. everything's coming together, the group chat is thriving ✨

but if link is not established, we return -E1000_ERR_PHY (-2). not the slay we were hoping for, ngl 😭

no link = -E1000_ERR_PHY (-2). that's the error code, memorize it, it's giving homework reminder 💀

💜 SEE ALSO 💜

the kernel file lives over here, iconic address:

and now the full playlist — every single one of these, no skips, no shuffling, we listen to the whole album 🔥:

like, that's a whole friend group and every one of them matters 💜 no cap.

and that's the page! this lil drop was sourced from ./drivers/net/ethernet/intel/e... (yes, it really is cut off exactly like that, we don't gatekeep truncation 💀) and it's dated October 2026. stay slay, stay linked, mwah 😘💅✨
