💖 iavf_legacy_rx_csum(9) — Kernel API Manual 💖

okay bestie, welcome to the iavf_legacy_rx_csum(9) page in the Kernel API Manual 💅 this is the little kernel helper that does the “did hw indicate a good checksum?” note in the skb, and we’re keeping every single detail. no cap.

---

✨ NAME ✨

iavf_legacy_rx_csum — indicate in skb if hw indicated a good checksum 💫

---

🦋 SYNOPSIS 🦋

struct libeth_rx_csum iavf_legacy_rx_csum (const struct iavf_vsi *vsi ,
u64 qw1 , const struct libeth_rx_pt decoded_pt );

---

🎀 ARGUMENTS 🎀

• vsi — the VSI we care about 💅
• qw1 — quad word 1 🧚
• decoded_pt — decoded packet type 🌸

---

💅 DESCRIPTION 💅

so here’s the tea: this function only operates on the VIRTCHNL_RXDID_1_32B_BASE legacy 32byte descriptor writeback format. that’s the whole format situation, bestie — no other format energy here. 🫶

---

⭐ RETURN ⭐

it returns decoded checksum bits, periodt. 💖
