igb_setup_link(9)

💖 igb_setup_link(9) 💖

okay so welcome to igb_setup_link(9), straight out of the Kernel API Manual — yes bestie, we're in kernel land now 🌈✨.

🌸 NAME 🌸

igb_setup_link — setup flow control and link settings 💅

✨ SYNOPSIS ✨

s32 igb_setup_link (struct e1000_hw *hw );

🎀 ARGUMENTS 🎀

• hw — pointer to the HW structure 🫶 literally just a pointer to the HW structure, no extra lore.

🦋 DESCRIPTION 🦋

okay so here's the tea: igb_setup_link determines which flow control settings to use, then configures flow control. after that it calls the appropriate media-specific link configuration function. assuming the adapter has a valid link partner, a valid link should be established. it also assumes the hardware has previously been reset, and that the transmitter and receiver are not enabled — so like, that's the vibe it's expecting, periodt 💀✨.
