nfp_nfdk_rx_csum(9)

🎀 NAME 🎀

okay bestie, meet nfp_nfdk_rx_csum(9) — the function whose whole entire job is to set the SKB checksum field based on RX descriptor flags. that’s the vibe, that’s the lore, and it’s giving “small but crucial.” 💅✨

✨ SYNOPSIS ✨

       void nfp_nfdk_rx_csum (struct nfp_net_dp *dp , struct nfp_net_r_vector
       *r_vec , struct nfp_net_rx_desc *rxd , struct nfp_meta_parsed *meta ,
       struct sk_buff *skb );

🌸 ARGUMENTS 🌸

• dp — the NFP Net data path struct. yes bestie, that exact struct. 🫶
• r_vec — the per-ring structure. it’s giving ring-specific main character energy. 🎀
• rxd — Pointer to RX descriptor. literally a pointer to the RX descriptor. 👑
• meta — Parsed metadata prepend. the parsed metadata prepend, periodt. 🦋
• skb — Pointer to SKB. pointer to the SKB, no cap. 💖
