🌸 NAME 🌸

__dev_mc_unsync — remove synchronized addresses from a device. it's giving cleanup era 🧹✨

🦋 SYNOPSIS 🦋

void __dev_mc_unsync (struct net_device *dev , int (*unsync)(struct
net_device *, const unsigned char *) );

like, that's the whole signature. no cap, that's it 👑

💖 ARGUMENTS 💖

• dev — the device to sync. it's the main character here 🫶
• unsync — the function to call if an address should be removed. yes, it's a callback, yes it's iconic 💅

🎀 DESCRIPTION 🎀

so basically: this removes all the addresses that were previously added to the device by dev_mc_sync. literally all of them. it's the uno reverse card for syncing 🔄💀

no extra lore, no hidden behaviour — that's the entire description. periodt. ✨
