iavf_flex_rx_csum(9)

💖 iavf_flex_rx_csum(9) 💖

okay bestie, welcome to your Kernel API Manual moment — this one is iavf_flex_rx_csum(9), and it's literally about telling the skb whether the hardware said the checksum was good. no cap, it's a tiny helper with main-character energy. 🫶

✨ NAME ✨

iavf_flex_rx_csum — indicate in the skb if the hardware indicated a good checksum. 💅

🌸 SYNOPSIS 🌸

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

🎀 ARGUMENTS 🎀

• vsi — the VSI we care about. yes, that exact one. 👑
• qw1 — quad word 1, periodt.
• decoded_pt — decoded packet type, slay.

🦋 DESCRIPTION 🦋

okay so here's the vibe check: this function operates only on the VIRTCHNL_RXDID_2_FLEX_SQ_NIC flexible descriptor writeback format. that's the whole scope, bestie. ✨

important: that only is doing a lot of work — VIRTCHNL_RXDID_2_FLEX_SQ_NIC is the flexible descriptor writeback format this function handles. 💀

🔥 RETURN 🔥

it returns the decoded checksum bits. that's the whole vibe. 🍓
