STRUCT NVME_TCP_HDR(9)

✨ struct nvme_tcp_hdr(9) ✨

okay so bestie, welcome to the Kernel API Manual 💖 this one's a lil struct from the kernel side of things — section 9, kernel-API territory — and it's literally the common header for nvme tcp pdus. tiny struct, big main character energy 👑

---

🌸 NAME 🌸

struct nvme_tcp_hdr — the nvme tcp pdu common header, aka the lil envelope every pdu wears 🎀

---

🦋 SYNOPSIS 🦋

struct nvme_tcp_hdr {
    __u8 type;
    __u8 flags;
    __u8 hlen;
    __u8 pdo;
    __le32 plen;
 };

ngl that trailing }; is spaced exactly like the original — copy it verbatim, don't "fix" it, we don't do that here 💅

---

💜 Members 💜

• type — pdu type. the vibe check, basically: what kind of pdu is this 🏷️
• flags — pdu specific flags. the lil mood ring for this particular pdu, one per type ✨
• hlen — pdu header length. how long the header itself is, in case you were wondering 👀
• pdo — pdu data offset. where the data starts, so you're not out here searching 😌
• plen — pdu wire byte length. how many bytes actually go over the wire, fr fr 📏

🌈 SEE ALSO 🌈

• Kernel file ./include/linux/nvme-tcp.h — go read the source bestie, it's all there 🫶

lowkey the whole struct is five fields and none of them are mysterious. iconic behavior honestly 🌟

that's the whole page, no notes 💅 and yes, this was struct nvme_tcp_hdr(9) from ./include/linux, dated October 2026 — catch you in the next reboot, bestie 🦋🎀💖
