🌸 NAME 🌸

okay so bestie, this is the page for e1000_copper...k_postconfig(9) from the Kernel API Manual, and the actual function is e1000_copper_link_postconfig β€” post link setup. That's the whole vibe: after-link glow-up energy ✨.

✨ SYNOPSIS ✨

s32 e1000_copper_link_postconfig (struct e1000_hw *hw );

πŸ’… ARGUMENTS πŸ’…

  • hw β€” Struct containing variables accessed by shared code. πŸ’–

πŸ¦‹ DESCRIPTION πŸ¦‹

So literally, this one configs the MAC and the PHY after the link is up. Here's the step-by-step, periodt:

  1. Set up the MAC to the current PHY speed/duplex if we are on 82543. If we are on newer silicon, we only need to configure collision distance in the Transmit Control Register.
  2. Set up flow control on the MAC to that established with the link partner.
  3. Config DSP to improve Gigabit link quality for some PHY revisions.
