💖 ixgbe_write_mc_addr_list(9) — Kernel API Manual 💖

okay so bestie, we're in the kernel docs today (yes, that kernel), and this page is about ixgbe_write_mc_addr_list. It's a little function with a big job: it's the one that pushes your multicast addresses into the MTA. Real "quiet kid in the back of the class who actually runs the group project" energy. ✨

🌸 NAME 🌸

ixgbe_write_mc_addr_list — write multicast addresses to MTA. That's it, that's the whole vibe. 🎀

🦋 SYNOPSIS 🦋

int ixgbe_write_mc_addr_list (struct net_device *netdev );

One function, one argument, one int coming back at you. Lowkey elegant ngl. 💅

🍓 ARGUMENTS 🍓

  • netdev — the network interface device structure. It's the struct that holds everything about the interface you're touching. Main character struct, honestly. 👑

✨ DESCRIPTION ✨

So what does it DO? It writes the multicast address list into the MTA hash table. That's the whole description, bestie — no hidden bonus features, no secret side quests. It takes the multicast addrs and drops them into the MTA hash table, and that's the tea. 🫖🦋

💜 RETURN 💜

  • -ENOMEM — on failure. (Out of memory, it's giving "we ran out of room bestie 😭")
  • 0 — when no addresses were written.
  • X — when it writes X addresses to the MTA. So the return value is literally the count of addresses that made it in. Slay. 🎀

🌈 SEE ALSO 🌈

The source file itself lives here, no cap:

  • ./drivers/net/ethernet/intel/ixgbe/ixgbe_main.c

and then the whole extended friend group, because kernel functions travel in packs apparently 🔥:

and that's the page bestie!! 🫶 this lil beauty comes from ./drivers/net/ethernet/intel/i..., dated October 2026, and it's filed under ixgbe_write_mc_addr_list(9) in the Kernel API Manual. go forth and write those multicast addresses 💅✨🎀
