STRUCT NFT_PIPAPO_MATCH(9)

💖 struct nft_pipapo_match(9) 💖

okay so bestie, this page is straight out of the Kernel API Manual, and it's literally all about struct nft_pipapo_match — the data used for lookup and matching. no cap, that's the whole vibe ✨

🌸 NAME 🌸

struct nft_pipapo_match — data used for lookup and matching 💅

🎀 SYNOPSIS 🎀

here's the whole shape, bestie — exact characters, no funny business:

struct nft_pipapo_match {
    u8 field_count;
    enum nft_pipapo_clone_state state:8;
    unsigned int bsize_max;
    struct nft_pipapo_scratch * __percpu *scratch;
    struct rcu_head rcu;
    struct nft_pipapo_field f[];
 };

🧚 Members 🧚

• field_count (u8) — the amount of fields in the set. literally the field count, she's booked and busy ✨
• state (enum nft_pipapo_clone_state state:8) — the add/delete state; it's used from the control plane. control-plane main character energy 👑
• bsize_max (unsigned int) — the maximum lookup table bucket size of all fields, measured in longs. yes, longs, not vibes 🫶
• scratch (struct nft_pipapo_scratch * __percpu *scratch) — preallocated per-CPU maps for partial matching results. so prepared, so slay 💅
• rcu (struct rcu_head rcu) — matching data is swapped on commits. she's doing the swap 🔁
• f (struct nft_pipapo_field f[]) — the fields, with their lookup and mapping tables. iconic little array 🌈
