igb_copper_link_autoneg(9)

📦 version 7.3.1, in nixpkgs unstable

okay bestie, so this one is a page from the Kernel API Manual (yes, that's the manual name, we're fancy now 💅) and it's all about getting your copper link to, like, introduce itself properly. Let's go 🫶

🌸 NAME 🌸

igb_copper_link_autoneg — setup/enable autoneg for copper link

like literally the function that makes your copper PHY and its link partner sit down and agree on how fast they're gonna talk ✨

🦋 SYNOPSIS 🦋

s32 igb_copper_link_autoneg (struct e1000_hw *hw );

that's the whole vibe check right there 👑

🎀 ARGUMENTS 🎀

  • hw — pointer to the HW structure. that's it, that's the argument 💖

⭐ DESCRIPTION ⭐

okay so here's what she does 👇

She performs initial bounds checking on the autoneg advertisement parameter first — gotta make sure the numbers actually make sense before we go shouting them at the link partner, no cap 🧚

Then she configures stuff to advertise the full capability — like, telling the world everything she can do. main character energy fr fr 💅

Then she sets up the PHY to autoneg and restarts the negotiation process between the link and the link partner — so the two of them can sort out their whole situationship 😭

And if autoneg_wait_to_complete is set? She waits for autoneg to complete before exiting. polite queen behavior, she doesn't just dip mid-conversation 🌸
