📦 version 7.3.1, in nixpkgs unstable

💖 e1000e_write_uc_addr_list(9) 💖

okay so bestie, this is a page straight out of the Kernel API Manual (yes, the Kernel API Manual, we're literally in the big leagues now 🫶) and it's all about one little function called e1000e_write_uc_addr_list. It's an Intel ethernet girlie thing. Sit down, hydrate, let's go ✨

🌸 NAME 🌸

e1000e_write_uc_addr_list — write unicast addresses to the RAR table

like, that's the whole vibe. unicast addresses in, RAR table out. no cap 💅

🦋 SYNOPSIS 🦋

int e1000e_write_uc_addr_list (struct net_device *netdev );

that's it. one argument. one int coming back at you. iconic behaviour honestly 🎀

🍓 ARGUMENTS 🍓

  • netdev — the network interface device structure, aka the network device struct. yes queen, that's the one 👑

✨ DESCRIPTION ✨

So what does she do? She writes the unicast address list to the RAR table. That's the entire job description, bestie — she takes the unicast addresses and she puts them in the RAR table. Obsessed with a function that knows exactly what it is 🔥

💜 RETURN 💜

Here's the vibe check on what comes back at you:

  • -ENOMEM — on failure, or when there's insufficient address space 😭
  • 0 — when no addresses were written 🙈
  • X — when X addresses get written to the RAR table 💀 (yes, literally the number of addresses — she returns the count, main character energy)

🌈 SEE ALSO 🌈

the way that this list is long — but every single one of these is invited to the party, no gatekeeping here 💖

the kernel file herself lives at:

  • ./drivers/net/ethernet/intel/e1000e/netdev.c

and now the whole extended friend group:

iykyk 😌

ngl bestie, if -ENOMEM shows up it means failure or insufficient address space — don't come for me, that's just what the page says 🫶

okay that's the whole page, mwah 💋 this came from ./drivers/net/ethernet/intel/e... and it's dated October 2026 — so she's from the future, lowkey iconic, periodt ⭐🧚💜
