💖 call_netdevi...otifiers_mtu(9) 💖

okay so bestie, welcome to the Kernel API Manual — yes, we're doing kernel networking today, and yes, it's giving main character energy 🌈. This little icon is literally just the group-chat broadcast button for the network stack. Let's get into it 🫶

✨ NAME ✨

call_netdevice_notifiers_mtu — call all the network notifier blocks. every single one. no skipping. periodt 💅

🎀 SYNOPSIS 🎀

int call_netdevice_notifiers_mtu (unsigned long val , struct net_device
*dev , u32 arg );

🌸 ARGUMENTS 🌸

  • val — a unsigned long value that gets passed unmodified straight through to the notifier function. no editing, no vibes-checking, it goes in exactly as it came 🦋
  • dev — the net_device pointer, also passed unmodified to the notifier function. hands off, she's just the messenger 💅
  • arg — one extra u32 argument that gets handed to the notifier function. a little bonus parameter, a little treat 🍓

🔥 DESCRIPTION 🔥

Call all network notifier blocks. that's it, that's the whole job 👑

The parameters and the return value are exactly as for raw_notifier_call_chain. so if you already know that one, you already know this one — iykyk 😌✨

👑 SEE ALSO 👑

like I said. everybody. 💀💖
