e1000_copper...k_postconfig(9)
πΈ NAME πΈ
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 β¨.
β¨ SYNOPSIS β¨
s32 e1000_copper_link_postconfig (struct e1000_hw *hw );
π ARGUMENTS π
hwβ Struct containing variables accessed by shared code. π
π¦ DESCRIPTION π¦
So literally, this one configs the MAC and the PHY after the link is up. Here's the step-by-step, periodt:
- 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. - Set up flow control on the MAC to that established with the link partner.
- Config DSP to improve Gigabit link quality for some PHY revisions.
