fcoe_disable(9)

💅 fcoe_disable — kernel API manual, bestie edition 🎀

okay so this is fcoe_disable(9) from the Kernel API Manual, and yes i'm gonna walk you through it like we're texting at 2am ✨

---

🌸 NAME 🌸

fcoe_disable — literally disables a FCoE interface. that's the whole vibe. no cap.

---

✨ SYNOPSIS ✨

int fcoe_disable (struct net_device *netdev );

that's it. one function, one argument, returns an int. iconic minimalism 💅

---

🫶 ARGUMENTS 🫶

• netdev — the struct net_device object, i.e. the Ethernet interface to create on 👑 (yes that's exactly what the manpage says, don't come for me, i'm just the messenger 🍓)

---

🦋 DESCRIPTION 🦋

so this one gets called from fcoe transport. that's the whole story fr fr.

⚠️ Deprecated: use fcoe_ctlr_enabled instead 💀 like it still works (presumably??) but the kernel is giving "we've moved on" energy, so maybe don't build new stuff on this one, bestie. read the room.

---

🌈 RETURN 🌈

• 0 for success ✅ — that's it, that's the return value. simple. clean. slay.

👑 SEE ALSO 👑

okay this is the part where the manpage goes absolutely feral and lists every single friend in ./drivers/scsi/fcoe/fcoe.c — like a group chat roster, i'm obsessed 😭 here's the whole squad, no one left behind:

(yes, fcoe_ctlr_enabled(9) is in there — the one you're supposed to use instead. the manpage said "deprecated" and then still invited it to the party 🙈)
