ice_devlink_port_unsplit(9)

📦 version 7.3.1, in nixpkgs unstable

okay bestie, grab your iced coffee because we're diving into the Kernel API Manual, section 9 — this one's all about the devlink handler called .port_unsplit, and honestly? it's giving "undo button energy" 🎀

🌸 NAME 🌸

ice_devlink_port_unsplit — the .port_unsplit devlink handler, periodt 💅

✨ SYNOPSIS ✨

int ice_devlink_port_unsplit (struct devlink *devlink , struct
       devlink_port *port , struct netlink_ext_ack *extack );

like, that's the whole signature, no cap 🫶

🦋 ARGUMENTS 🦋

  • devlink — the devlink instance structure, your main character 🫶
  • port — the devlink port structure, living its best life
  • extack — the extended netdev ack structure (yes it's a real thing, iykyk)

💖 DESCRIPTION 💖

So this is the callback for the devlink .port_unsplit operation — literally what runs when someone wants to un-split. And the way it works? It just calls ice_devlink_port_split with the split count set to 1. simple, iconic, done 🔥

⚠️ heads up bestie: there could be no FW option available with split count 1. so like, don't come for me if that happens, the firmware said no 😭

⭐ RETURN ⭐

zero on success, or an error code on failure. slay when it works, 💀 when it doesn't, that's just how it is.
