e1000_setup..._serdes_link(9)

📦 version 7.3.1, in nixpkgs unstable

okay bestie, so this is a page from the Kernel API Manual, section 9, and it's all about one very specific little function that gets your fiber or serdes link all dressed and ready. it's giving "backstage pass to the network driver" ✨

🌸 NAME 🌸

e1000_setup_fiber_serdes_link — the glow-up artist that prepares a fiber or serdes link 🧚

⭐ SYNOPSIS ⭐

s32 e1000_setup_fiber_serdes_link (struct e1000_hw *hw );

🎀 ARGUMENTS 🎀

  • hw — the struct holding all the variables that the shared code pokes at. it's the main character of this whole operation, no cap 🫶

🦋 DESCRIPTION 🦋

so what does it do? it manipulates the Physical Coding Sublayer functions in order to configure the link 💫 highkey iconic behavior.

⚠️ okay so important vibe check: this function assumes the hardware has previously been reset and that the transmitter and receiver are not enabled. don't come at it with a live, running link and expect magic — it will not slay, it will just be confused 😭
