__libeth_xdp_run_flush(9)

📦 version 7.3.1, in nixpkgs unstable

💅 __libeth_xdp_run_flush (9) — from the Kernel API Manual, bestie 🎀

okay so picture this: it's a kernel manual page, right, and it's about running an XDP program and handling what happens when the prog says XDP_TX. that's the whole vibe. it's giving "internal helper energy" and honestly? iconic. ✨

🌸 NAME 🌸

__libeth_xdp_run_flush — run the XDP program and handle the XDP_TX verdict, no cap 💅

🦋 SYNOPSIS 🦋

u32 __libeth_xdp_run_flush (struct libeth_xdp_buff *xdp , struct
libeth_xdp_tx_bulk *bq , u32 (*run)(struct libeth_xdp_buff *xdp, const
struct libeth_xdp_tx_bulk *bq) , bool (*queue)(struct libeth_xdp_tx_bulk
*bq, struct libeth_xdp_buff *xdp, bool (*flush_bulk) (struct
libeth_xdp_tx_bulk *bq, u32 flags)) , bool (*flush_bulk)(struct
libeth_xdp_tx_bulk *bq, u32 flags) );

like, yes, that's a lot of function pointers. she's complex. she's worth it. 🫶

🎀 ARGUMENTS 🎀

  • xdp — the XDP buffer you're running the prog on. the main character of this whole operation 💖
  • bq — the buffer bulk used for XDP_TX queueing. this is where the frames go to hang out 🦋
  • run — an internal callback for running the XDP program. it does the actual prog-running thing ✨
  • queue — an internal callback for queueing an XDP_TX frame. lowkey the whole point of the flush situation 🌸
  • flush_bulk — the driver callback for flushing a bulk. yes bestie, the driver brings this one 👑

💜 DESCRIPTION 💜

so this is an internal inline abstraction — and when i say internal, i mean it — that runs the XDP program and additionally handles the XDP_TX verdict. both things. at once. multitasking queen 👑

it's used by both XDP and XSk, which is exactly why you see both run and queue hanging out in the signature. iykyk 🧚

⚠️ Do not use directly. fr fr. this one is not for you, it's for the internals. respect the boundary 🙈

⭐ RETURN ⭐

returns the libeth_xdp prog verdict, depending on the prog's verdict. yeah, it's verdict-ception 💀 — whatever the prog decides is what comes back out.

🌈 SEE ALSO 🌈

okay this list is long and every single one of these deserves their flowers, so buckle up bestie 🍓

Kernel file ./include/net/libeth/xdp.h, plus:

like, go read them. they're all eating, honestly 🔥

and that's the whole page, bestie!! 🫶 this lil number lives in ./include/net/libeth, dated October 2026, and it's part of the Kernel API Manual — so next time you see __libeth_xdp_run_flush(9) out in the wild you'll know exactly what's tea. periodt. 💅✨
