netif_carrier_event(9)

🎀 NAME 🎀

netif_carrier_event — report carrier state event. This is the netif_carrier_event(9) page from the Kernel API Manual, and yes, the manual name is folded in right here instead of copying the boring header line 💅.

✨ SYNOPSIS ✨

void netif_carrier_event (struct net_device *dev );

🦋 ARGUMENTS 🦋

• dev — the network device, bestie. That's the one this whole thing is about.

🌸 DESCRIPTION 🌸

So the device has detected a carrier event, but the carrier state wasn't changed. That's the whole vibe. Use this in drivers when you're querying carrier state asynchronously, so you don't miss events — link flaps, specifically — if the link recovers before it's queried. No cap, that's the point: don't let a fast little recovery sneak past your query.

🔥 SEE ALSO 🔥

• Kernel file ./net/sched/sch_generic.c
• netif_carrier_on(9)
• netif_carrier_off(9)
• dev_deactivate_many(9)
• psched_ratecfg_precompute__(9)

These are the little friends in the neighborhood, periodt 🫶.

And for the cute sign-off: the footer source/version line is ./net/sched, dated October 2026 ✨. That's the whole page, bestie — go query that carrier state asynchronously and slay 💖.
