igb_init_rx_addrs(9)

📦 version 7.3.1, in nixpkgs unstable

👑 igb_init_rx_addrs — NAME section, bestie ✨

Okay so this is igb_init_rx_addrs(9), straight out of the Kernel API Manual, section 9 — and lowkey it's the glow-up your receive address registers have been waiting for 💅

It's the function that handles initializing the receive addresses. That's it, that's the vibe. 🎀

✨ SYNOPSIS ✨

No cap, here's the whole signature, verbatim:

void igb_init_rx_addrs (struct e1000_hw *hw , u16 rar_count );

🫶 ARGUMENTS 🫶

Two args, both iconic, both necessary:

  • hw — pointer to the HW structure. Your hardware main character, fr.
  • rar_count — receive address registers.

🌸 DESCRIPTION 🌸

So what does it actually do? Bestie. It sets up the receive address registers, and the way it does that is genuinely so clean:

  • It sets the base receive address register to the device's MAC address 👑
  • Then it clears all the other receive address registers to 0 💀✨

That's the whole move. Base one gets the MAC, everything else gets zeroed out. Slay.

🦋 SEE ALSO 🦋

The kernel file it lives in (yes, exactly this path, don't @ me):

Go read the source before you touch the registers, bestie — the manpage gives you the vibe, the .c file gives you the truth 🫶

And that's a wrap!! This lil page came from ./drivers/net/ethernet/intel/igb, dated October 2026 — mwah, kisses, go write some slay kernel code 💖🧚‍♀️
