__dev_mc_sync(9)

💅 __dev_mc_sync(9) — Kernel API Manual 💅

okay bestie, welcome to the Kernel API Manual moment for __dev_mc_sync(9) ✨ this is the device’s multicast-list sync situation, and it’s giving “keep the address list current” energy fr fr 🦋

🌸 NAME 🌸

__dev_mc_sync — synchronize device's multicast list 💖

✨ SYNOPSIS ✨

int __dev_mc_sync (struct net_device *dev , int (*sync)(struct
       net_device *, const unsigned char *) , int (*unsync)(struct
       net_device *, const unsigned char *) );

🎀 ARGUMENTS 🎀

• dev — device to sync 🫶
• sync — function to call if address should be added ✨
• unsync — function to call if address should be removed 💅

🔥 DESCRIPTION 🔥

the way that this just adds newly added addresses to the interface and releases addresses that have been deleted is lowkey iconic. that’s the whole job, bestie: new addresses go in, deleted addresses get released, periodt 💜
