igb_copper_l...tup_m88_gen2(9)

✨ NAME ✨

okay so welcome to the igb_copper_l...tup_m88_gen2(9) page from the Kernel API Manual 💖 the function is igb_copper_link_setup_m88_gen2, and its whole little mission is Setup m88 PHY's for copper link. that's the name, no cap.

🦋 SYNOPSIS 🦋

the call is literally this, bestie — keep it exact:

s32 igb_copper_link_setup_m88_gen2 (struct e1000_hw *hw );

🎀 ARGUMENTS 🎀

• hw — pointer to the HW structure. that's the one argument, periodt.

🌸 DESCRIPTION 🌸

so this function sets up MDI/MDI-X and polarity for the i347-AT4, m88e1322, and m88e1112 PHY's. iconic.

it also enables and sets the downshift parameters. yep, that's the whole description — short and slay.
