📦 version 7.3.1, in nixpkgs unstable

💅 igc_write_mc_addr_list(9) — from the Kernel API Manual, bestie 🎀

okay so real talk, this page is igc_write_mc_addr_list(9) out of the Kernel API Manual, and it's short but she's iconic. buckle up, it's like four lines of actual content and a SEE ALSO list that goes on forever (iykyk).

✨ NAME ✨

igc_write_mc_addr_list — write multicast addresses to MTA 🦋

🌸 SYNOPSIS 🌸

int igc_write_mc_addr_list (struct net_device *netdev );

literally just one function, one argument, no drama 💅

🎀 ARGUMENTS 🎀

  • netdev — the network interface device structure, aka the main character of this whole operation 👑

💖 DESCRIPTION 💖

So what she does is: she writes the multicast address list to the MTA hash table. That's it. That's the whole vibe. ✨

no cap, that's the entire description in the original and I'm not gonna invent lore for you 🫶

🔥 RETURN 🔥

Here's the vibe check on what you get back:

  • -ENOMEM — on failure 😭 (memory said no)
  • 0 — on no addresses written
  • X — on writing X addresses to MTA 👑

lowkey obsessed with how a function this short has a friend group this big 💀

and that's the whole page, bestie 🫶 source is ./drivers/net/ethernet/intel/igc, dated October 2026 — mwah, slay, go write some multicast addresses ✨🎀💖
