STRUCT DEVLINK_DPIPE_MATCH(9)

💅 struct devlink_dpipe_match(9) — from the Kernel API Manual, bestie 💅

okay so picture this: you're deep in the kernel, you open the devlink header, and this little struct is sitting there being iconic. it "represents match operation" — that's the whole vibe, that's the name line, periodt. it's the thing that says "hey, this is what we're matching on" in the dpipe world, and honestly? it ate. 💖

✨ SYNOPSIS ✨

struct devlink_dpipe_match {
    enum devlink_dpipe_match_type type;
    unsigned int header_index;
    struct devlink_dpipe_header *header;
    unsigned int field_id;
};

like, that's the whole struct. four little members, four little besties, all doing their part. 🫶

🌸 Members 🌸

• type — the type of match. literally what kind of match operation this is. that's it, that's the whole job, and it's doing it beautifully. 👑
• header_index — the header index, and ngl this one's lowkey important: packets can have several headers of the same type, like in the case of tunnels. so yeah, index isn't just decoration, it's how you tell your tunnel headers apart. iykyk. 🌀
• header — the header. yes bestie, that's the description, it's giving "minimalist" and we respect it. ✨
• field_id — the field index. which field inside the header we're matching on. slay. 🎀

💀 real talk though: this page is dated October 2026 and comes from ./include/net, so if you're reading a different kernel tree, do a lil vibe check on the source before you trust every line. no cap.
