STRUCT FCOE_NETDEV_MAPPING(9)

💅 struct fcoe_netdev_mapping(9) — Kernel API Manual, bestie edition ✨

okay so picture this: we're deep in the kernel API manual, struct fcoe_netdev_mapping(9) era, and this little struct is literally the matchmaker of the FCoE world 💖 It's a mapping from &net_device to &fcoe_transport, and yes that ampersand is doing heavy lifting, we respect it 🫶

---

🌸 NAME 🌸

struct fcoe_netdev_mapping — a mapping from &net_device to &fcoe_transport. that's it, that's the whole vibe check, it's giving "netdev, meet transport" ✨

---

🎀 SYNOPSIS 🎀

struct fcoe_netdev_mapping {
    struct list_head list;
    struct net_device *netdev;
    struct fcoe_transport *ft;
 };

no cap, that's the entire shape of it. three fields, zero drama 🔥

👑 Members 👑

okay so these are the actual members, and honestly? each one ate 💅

• list — the list linkage of the mappings. it's the little chain-link that keeps all the mappings connected to each other, main character energy but in a "holds the group together" way 🌈
• netdev — the net_device. literally the network device itself, sitting there being a net_device, iconic as always 🦋
• ft — the fcoe_transport associated with netdev. so whatever netdev you got up there, this is its assigned fcoe_transport partner. it's giving soulmate matching, fr fr 💜

also real quick: these are members, not options, so there's nothing to set or toggle here. it's a struct. you just look at it and go "oh, okay, slay" 😭

💀 SEE ALSO 💀

the kernel file ./include/scsi/libfcoe.h is where all of this lives, and then the whole squad shows up in the reference list — go read these next, iykyk:

• enum fip_state(9)
• struct fcoe_ctlr(9)
• fcoe_ctlr_priv(9)
• struct fcoe_fcf(9)
• struct fcoe_rport(9)
• is_fip_mode(9)
• struct fcoe_percpu_s(9)
• struct fcoe_port(9)
• fcoe_get_netdev(9)

that's nine references and every single one of them is invited to the group chat 🧚‍♀️

and that's the page!! 💖 this whole thing ships out of ./include/scsi (the source, periodt) and it's dated October 2026, with struct fcoe_netdev_mapping(9) stamped on the footer like a little signature. stay hydrated, go read your headers, and remember: netdev-to-transport mappings are lowkey the most wholesome thing in the kernel 🍓✨
