idpf_rx_singleq_flex_csum(9)

📦 version 7.3.1, in nixpkgs unstable

✨ idpf_rx_singleq_flex_csum ✨

okay so bestie, this one's a little kernel function from the idpf driver gang — it's a 9-section manual page, the kind you read when you're deep in the networking guts of Linux 💅

🌸 NAME 🌸

idpf_rx_singleq_flex_csum — literally tells the skb whether the hardware said the checksum was good 😌 no cap, that's the whole vibe.

🎀 SYNOPSIS 🎀

struct libeth_rx_csum idpf_rx_singleq_flex_csum (const union
       virtchnl2_rx_desc *rx_desc );

so she takes one arg and hands you back a struct libeth_rx_csum — cute, focused, knows what she wants 🫶

🦋 ARGUMENTS 🦋

  • rx_desc — the receive descriptor 💖 that's it, that's the whole input. she reads it and judges the checksum energy.

✨ DESCRIPTION ✨

so here's the tea: this function only operates on the VIRTCHNL2_RXDID_2_FLEX_SQ_NIC flexible descriptor writeback format 🔥 like, that's her whole lane. don't come at her with other formats, she's not doing it 🙈

it's giving "specialist", it's giving "i know my descriptor format and i'm not sorry" 👑

💜 RETURN 💜

parsed checksum status ⭐ — that's it, that's the return value, and honestly? iconic.

🌈 SEE ALSO 🌈

the kernel file lives right here: ./drivers/net/ethernet/intel/idpf/idpf_singleq_txrx.c 🎀

and the whole friend group, in order:

go say hi to all of them bestie, they're all in the same file and they all ate 💅

ngl, if you're poking around here you're probably already deep in the Intel idpf receive path — stay hydrated and read your descriptor formats 💖

and that's a wrap, gorgeous 🌸 this page came from ./drivers/net/ethernet/intel/idpf and it's dated October 2026 — idpf_rx_singleq_flex_csum(9), signing off 🎀✨
