ENUM NFT_RULE_COMPAT_ATTRIBUTES(9)

💅 NAME 💅

enum nft_rule_compat_attributes — the nf_tables rule compat attributes, bestie. It lives in the Kernel API Manual, and yes it's as niche as it sounds, but we love her anyway 🎀

✨ SYNOPSIS ✨

enum nft_rule_compat_attributes {
    NFTA_RULE_COMPAT_UNSPEC ,
    NFTA_RULE_COMPAT_PROTO ,
    NFTA_RULE_COMPAT_FLAGS ,
    __NFTA_RULE_COMPAT_MAX

};

🧚 Constants 🧚

Ok so there's literally four of them, and two of them are, like, shy 🙈 — the manpage just says -- undescribed --, which is giving "no thoughts, head empty" energy. Here's the whole roster, no gatekeeping:

• NFTA_RULE_COMPAT_UNSPEC — -- undescribed -- (she's mysterious, she's iconic, we know nothing 👑)
• NFTA_RULE_COMPAT_PROTO — the numeric value of the handled protocol, and it's typed as NLA_U32 fr fr 🔥
• NFTA_RULE_COMPAT_FLAGS — a bitmask of enum nft_rule_compat_flags, also typed NLA_U32, slay 💅
• __NFTA_RULE_COMPAT_MAX — -- undescribed -- (the sentinel bestie, also undescribed 😭)

ngl, the two -- undescribed -- ones are literally just left blank in the source page. Not me making stuff up to fill the silence — the facts stay facts 💀

periodt 💖 That's the whole page, no crumbs left behind. This little beauty ships from ./include/uapi/linux/netfilter and the page itself is dated October 2026 — so like, future icon behavior honestly 🫶✨ Go read the kernel header, ily, bye! 🌸
