LIBETH_XDP_DEFINE_RUN_PROG(9)

📦 version 7.3.1, in nixpkgs unstable

💅 LIBETH_XDP_DEFINE_RUN_PROG 💅

okay so bestie, this is a page from the Kernel API Manual (libeth_xdp_define_run_prog(9), section 9, iykyk) and it's literally just one macro that builds a whole function for you, so let's get into it ✨

🎀 NAME 🎀

LIBETH_XDP_DEFINE_RUN_PROG — define a driver XDP program run function 🦋

Like, it makes the function. You don't write the function. The macro writes the function. main character energy, honestly 👑

🌸 SYNOPSIS 🌸

LIBETH_XDP_DEFINE_RUN_PROG (name , flush );

that's it. that's the whole call. two things in, one function out 💖

✨ ARGUMENTS ✨

  • name — the name of the function you want to define 🏷️ like, whatever you call it is what it's gonna be called, no cap
  • flush — the driver callback that flushes an `XDP_TX` bulk 🚿🫧 (yes, it's a bulk, and yes, someone's gotta flush it)

🫶 SEE ALSO 🫶

okay this is the part where the page just dumps the entire friend group and honestly? iconic. no gatekeeping here, the whole ./include/net/libeth/xdp.h fam shows up 💀

also bestie, notice enum (anonymous)(9) shows up twice — that's not a typo on my end, that's literally what the page says, so I'm keeping it fr fr 🙈

and that's the whole page! before you go — the source file lives at ./include/net/libeth and this edition is dated October 2026 🗓️✨ so yeah, go define that run function, you're gonna slay it 💜🎀🦋
