💅 dev_mc_del_global(9) — like, the Kernel API Manual bestie 🌸

okay so real talk, this page is from the Kernel API Manual and it's all about dev_mc_del_global(9). yes that's a lot of underscores, no we're not scared of them 💖

✨ NAME ✨

dev_mc_del_global — Delete a global multicast address. that's it, that's the whole vibe 🎀

🦋 SYNOPSIS 🦋

int dev_mc_del_global (struct net_device *dev , const unsigned char
       *addr );

look at her go 😭 so clean. so iconic.

🌸 ARGUMENTS 🌸

  • dev — device. the device. the one and only 👑
  • addr — address to delete. yes bestie, this is the one getting yeeted 🗑️✨

💜 DESCRIPTION 💜

okay so here's the tea 🍓 — this function releases the reference to a multicast address, and then it removes it from the device if the reference count drops to zero. that's the whole deal, no cap. like, the address is only actually gone-gone once literally nobody is holding a reference anymore. main character reference-counting energy fr fr 🔥

not me over here being dramatic about refcounts, but this is genuinely how it works 💅

🌈 SEE ALSO 🌈

okay so this is the part where I introduce you to the whole friend group 🫶 everyone here lives in the kernel file ./net/core/dev_addr_lists.c and honestly? the roster is LONG. buckle up:

like I said. a WHOLE friend group. every single one of them makes the list, not a single soul left out 💀💖

and that's the page!! mwah 💋 this beauty lives in ./net/core, dated October 2026, and she's filed under dev_mc_del_global(9) in the Kernel API Manual — go forth and delete those global multicast addresses responsibly bestie 🧚⭐
