e1000_hash_mc_addr(9)

📦 version 7.3.1, in nixpkgs unstable

💖 e1000_hash_mc_addr — okay bestie, let's talk multicast hashing 💖

So this is a page from the Kernel API Manual (section 9, the kernel-API girlies ✨) and it's all about one little function called e1000_hash_mc_addr. Buckle up, it's short but it eats. 🍓

✨ NAME ✨

e1000_hash_mc_addr — generate a multicast hash value 🎀

Like, that's literally the whole job. One function. One vibe. 👑

🌸 SYNOPSIS 🌸

u32 e1000_hash_mc_addr (struct e1000_hw *hw , u8 *mc_addr );

Notice the return type is u32 — she gives you back a 32-bit hash value, no cap. 💅

🦋 ARGUMENTS 🦋

  • hw — pointer to the HW structure. That's the hardware info she's working with, bestie. 🫶
  • mc_addr — pointer to a multicast address. The address getting hashed, periodt. 💜

🔥 DESCRIPTION 🔥

Okay so what does she actually do? She generates a multicast address hash value 💫 — and that hash value is the thing that gets used to determine the multicast filter table array address and the new table value. The way that one hash does double duty is genuinely iconic, ngl. 🌈

No extra options, no hidden caveats, no drama — just a hash value being born and immediately going to work. Main character energy fr fr. 👑

🎀 SEE ALSO 🎀

First up, the source file herself, iykyk:

  • Kernel file ./drivers/net/ethernet/intel/e1000e/mac.c 📁

And now the entire friend group 😭 — every single one of these, exactly as listed:

That's the whole squad, nobody left behind. 🫶💖

Ngl there's nothing dangerous on this page — it's just a hash value generator. But like, respect her, she's doing her part in the multicast filter table situation. 💅

And that's the page, bestie! 🧚 This one came from the source path that starts ./drivers/net/ethernet/intel/e... and it's dated October 2026 — and the manual name is e1000_hash_mc_addr(9), obviously, she's the moment. ⭐💜 Slay, go hash some multicast addresses. 🎀
