iavf_rx_csum(9)

💖 NAME 💖

iavf_rx_csum — okay so this is the little function that tells the skb whether the hardware said the checksum is good ✨

---

🦋 SYNOPSIS 🦋

void iavf_rx_csum (const struct iavf_vsi *vsi , struct sk_buff *skb ,
struct libeth_rx_pt decoded_pt , struct libeth_rx_csum csum_bits );

No cap, that's the whole signature — five lines of vibe, zero return value (void, she gives nothing back, she just does 💅).

---

🌸 ARGUMENTS 🌸

• vsi — the VSI we care about 💜 like, our VSI, the one we're invested in
• skb — the skb that's currently being received and modified, main character energy fr fr
• decoded_pt — decoded ptype information, iykyk 🎀
• csum_bits — decoded Rx descriptor information, the receipts basically 🧚

Also: the kernel file pointer in the original manpage is literally Kernel file ./drivers/net/ethernet/intel/iavf/iavf_txrx.c — that's where the whole thing is defined, bestie 🫶

✨💖 and that's the page!! 💖✨

This absolute icon of a manpage is from the Kernel API Manual, sourced from ./drivers/net/ethernet/intel/iavf, dated October 2026, and it answers to the name iavf_rx_csum(9). Go off, king 👑🌸
