STRUCT NVMET_FC_PORT_INFO(9)

✨ struct nvmet_fc_port_info — kernel API manual, bestie edition ✨

okay so this page is struct nvmet_fc_port_info(9) and it lives in the Kernel API Manual, and it is literally the little glow-up data element that holds port-specific ids plus FC connection-specific data — you use it while you're doing NVME Subsystem role registrations. that's the whole vibe. 💅

🌸 NAME 🌸

struct nvmet_fc_port_info — port-specific ids and FC connection-specific data element used during NVME Subsystem role registrations 🫶

---

🎀 SYNOPSIS 🎀

she's a struct, she's three fields, she's iconic:

struct nvmet_fc_port_info {
    u64 node_name;
    u64 port_name;
    u32 port_id;
 };

---

💖 Members 💖

• node_name — the FC WWNN for the port, bestie. that's it, that's the field. ✨
• port_name — the FC WWPN for the port. yes the names are similar, no you may not mix them up. 👑
• port_id — the FC N_Port_ID currently assigned to the port. ⚠️ the upper 8 bits must be set to 0 — not "should", must. do not test her. 💀

---

🦋 Description 🦋

Static fields describing the port being registered:

Initialization values for dynamic port fields:

ok so the original really does leave those two lines just sitting there like a vibe check with no follow-up — nothing else is spelled out on this page, and I'm not about to invent lore. 🙈
