ice_devlink_port_new(9)

📦 version 7.3.1, in nixpkgs unstable

Okay bestie, this one lives in the Kernel API Manual, section 9, and it's the function that literally births a brand-new devlink port. Iconic behavior, honestly. Let's get into it 🎀

✨ SYNOPSIS ✨

int ice_devlink_port_new (struct devlink *devlink , const struct
       devlink_port_new_attrs *new_attr , struct netlink_ext_ack *extack ,
       struct devlink_port **devlink_port );

🫶 ARGUMENTS 🫶

  • devlink — pointer to devlink. The main character of this whole situation 💜
  • new_attr — pointer to the port new attributes. Like, the vibes the new port is supposed to have ✨
  • extack — extack for reporting error messages. If something goes wrong, this is the one who tells everyone 😭
  • devlink_port — pointer to a new port. Yes queen, this is where the fresh port ends up 🦋

🌸 DESCRIPTION 🌸

So what actually happens here? ice_devlink_port_new creates a new devlink port, checks the new port attributes and rejects any unsupported parameters, and allocates a new subfunction for that port.

Periodt. Three things, all slaying:

  1. Creates the new devlink port 🎀
  2. Checks the new port attributes and rejects any unsupported parameters 🚫
  3. Allocates new subfunction for that port 👑

Lowkey a lot of responsibility for one function, and it's carrying it flawlessly.

⭐ RETURN ⭐

Zero on success, or an error code on failure. That's it, that's the whole mood.

No cap — if you get a nonzero back, something didn't eat and you need to go check your attributes 👀

🔥 SEE ALSO 🔥

The kernel file got its own shoutout, so here it is:

And then the whole friend group, in order, no one left out fr fr:

That's the whole group chat, bestie. Go read them too, iykyk 🌈

Alright, that's the page! Huge shoutout to the source it shipped from — ./drivers/net/ethernet/intel/i... (yes it's truncated like that, don't come for me 🙈) — version dating all the way to October 2026, and the page itself is ice_devlink_port_new(9). Bye bestie, go create some ports 💖✨🎀
