tb_switch_configure_link(9)

hiii bestie 💖 welcome to the tb_switch_configure_link(9) page from the Kernel API Manual ✨ this is giving “link configured” main character energy, and we're gonna make it make sense, no cap.

🌸 NAME 🌸

tb_switch_configure_link — Set link configured 💅

⭐ SYNOPSIS ⭐

okay so the whole signature is literally this:

int tb_switch_configure_link (struct tb_switch *sw );

🎀 ARGUMENTS 🎀

• sw — the switch whose link is configured 🫶

🦋 DESCRIPTION 🦋

okay so this one sets the link upstream from sw configured — from both ends — so that it will not be disconnected when the domain exits sleep 😴✨. It can be called for any switch, periodt. No gatekeeping.

It is recommended that this is called after lane bonding is enabled — like, do the lane bonding thing first, bestie 💅.

🔥 RETURN 🔥

0 on success, and a negative errno otherwise 😭. That's the return vibe, fr fr.
