STRUCT FC_DISC_PORT(9)

struct fc_disc_port(9) 🦋 — from the Kernel API Manual (yes we're reading kernel docs for fun now, iykyk)

okay so bestie. today we're looking at struct fc_disc_port, and honestly? it's giving humble little helper. the NAME says it all: it's a temporary discovery port to hold rport identifiers ✨ like a little sticky note for remote port IDs while the kernel is out here doing discovery stuff. short-lived, important, main character energy tbh 💅

✨ SYNOPSIS ✨

here's the whole struct, exactly as it lives, no cap:

struct fc_disc_port {
    struct fc_lport    *lp;
    struct list_head   peers;
    struct work_struct rport_work;
    u32 port_id;
 };

that's it. four members. tiny icon. we love a compact king 👑

🎀 Members 🎀

• lp — your Fibre Channel host port instance 💖 this is the whole host-port vibe this discovery port belongs to.
• peers — the node for list management during discovery and RSCN processing 🌸 translation: it's the little link that keeps this thing chained up in a list while discovery and RSCN stuff is going down.
• rport_work — a work struct for starting the rport state machine ⚙️✨ yeah. it kicks that state machine into gear. we respect a member that does actual work.
• port_id — the port ID of the discovered port 🫶 literally the ID. of the port. that got discovered. we stan a self-explanatory field.

ngl bestie, this struct is basically a temporary holding pen for rport identifiers — don't get attached, it's not staying forever 💀
