ENUM NFT_RANGE_OPS(9)

💅 enum nft_range_ops(9) — the nf_tables range operator, bestie

okay so this is a page straight out of the Kernel API Manual (section 9, kernel devs only, no gatekeeping here 🫶) and it's about enum nft_range_ops — the little enum that tells nf_tables which kind of range comparison you're doing. tiny enum? yes. important? also yes. let's get into it ✨

---

✨ NAME ✨

enum nft_range_ops — the nf_tables range operator 🎀

---

🌸 SYNOPSIS 🌸

enum nft_range_ops {
    NFT_RANGE_EQ ,
    NFT_RANGE_NEQ

};

like, that's the whole thing. two members, zero drama. she's compact and she knows it 💅

---

🦋 Constants 🦋

the constants are literally the entire personality of this enum, so let's meet them:

• NFT_RANGE_EQ — equal ✨ (the range op that says "equals")
• NFT_RANGE_NEQ — not equal 💀 (the range op that says "nope, not equal")

that's it. that's the whole cast. both iconic, both doing their one job flawlessly 🫶

first up, the source file herself, no cap:

and then. okay. take a breath bestie, because this is the friend group and it is huge 😭 every single one of these is a real enum with its own (9) manpage, and they all showed up to the party:

mwah, that's the page 💜 this beauty ships from ./include/uapi/linux/netfilter and the version tag on it is October 2026 — so mark your calendar, screenshot it, send it to the group chat, and stan a two-member enum that simply works. periodt. 🎀✨
