libfcoe_device_notification(9)

📦 version 7.3.1, in nixpkgs unstable

💖 libfcoe_device_notification — bestie's guide to net device events 💖

okay so real talk, this one is a kernel API manual page (section 9, the kernel API manual vibe), and the function is literally called libfcoe_device_notification. it's giving "small function, big job" energy tbh 🎀

✨ NAME ✨

libfcoe_device_notification — the handler for net device events, periodt 💅

🌸 SYNOPSIS 🌸

int libfcoe_device_notification (struct notifier_block *notifier , ulong event , void *ptr );

that's the whole signature bestie, no cap. int going in, int coming back out 🫶

🦋 ARGUMENTS 🦋

  • notifier — the context of the notification 👑 like, the little bundle of info that tells you what's up
  • event — the type of event 🎀 which flavour of thing happened
  • ptr — the net device that the event was on 🦋 yep, that net device, the one that did the thing

💜 DESCRIPTION 💜

so here's the tea ☕ — this function gets called by the Ethernet driver in case of a link change event. that's it, that's the whole job. the Ethernet driver rings it up when the link changes and this function picks up the phone 📞✨

no extra lore, no bonus behaviour, no secret side quests. literally just: link changes → driver calls this. iconic behaviour honestly 🌈

⭐ RETURN ⭐

  • 0 — for success ✅ that's it, that's the whole return situation. 0 for success, bestie 💖

🔥 SEE ALSO 🔥

🎀 the kernel file in question 🎀

  • ./drivers/scsi/fcoe/fcoe_transport.c — yes, that's the file, and yes you should go read it 🧚

💅 the whole friend group (all of these are (9) pages) 💅

like, that is a packed see-also section, and honestly? they all ate 💀🔥

tiny reminder bestie: this page lives in ./drivers/scsi/fcoe, so if you're lost, that's where home is 🏠💜

and that's the page!! it comes to you from the ./drivers/scsi/fcoe corner of the kernel, dated October 2026, and it's the libfcoe_device_notification(9) page — go forth and handle those net device events, you've got this 🫶💖✨
