💅 tb_port_set_lane_bonding(9) — a Kernel API Manual moment ✨

okay bestie, so this is the tb_port_set_lane_bonding(9) page from the Kernel API Manual, and it's honestly short but she's got range. let's get into it 🎀

✨ NAME ✨

tb_port_set_lane_bonding — Enable/disable lane bonding

like, that's it, that's the whole vibe. toggling lane bonding on and off. 💫

🌸 SYNOPSIS 🌸

int tb_port_set_lane_bonding (struct tb_port *port , bool bonding );

two args, one int coming back at you. no drama. 🦋

🎀 ARGUMENTS 🎀

  • port — the lane adapter in question, aka the thing you're doing the bonding to 👑
  • bonding — enable/disable bonding, literally just a bool, she's either on or off, no in-between 💅

🔥 DESCRIPTION 🔥

so what does she do? Enables or disables lane bonding. that's the assignment and she ate. 🍓

but — and this is the important part, pay attention bestie — this should be called after the target link width has been set (tb_port_set_link_width). order matters, don't be out here calling things out of sequence, that's not the vibe. ⭐

📌 also: in most cases one should use tb_port_lane_bonding_enable instead to enable lane bonding. like, this one works, but that's the one you probably actually want. iykyk 💜

🫶 RETURN 🫶

0 on success, negative errno otherwise. so if you get a negative number back, that's your sign, it's giving error, go check your errno. 😭
