💅 i40e_addr_to_hkey(9)

okay so bestie, welcome to the Kernel API Manual, section 9 — this is the little page for i40e_addr_to_hkey, and honestly? it's a short one. we love a concise icon. 🎀

u64 i40e_addr_to_hkey (const u8 *macaddr );

that's the whole vibe up there ^ get comfy, it's literally a one-job function.

✨ NAME ✨

i40e_addr_to_hkey — converts a 6-byte MAC Address to a u64 hash key. that's it. that's the function. no cap. 🦋

🌸 SYNOPSIS 🌸

u64 i40e_addr_to_hkey (const u8 *macaddr );

returns a u64, takes a const u8 * called macaddr. clean. minimal. main character energy. 👑

🎀 ARGUMENTS 🎀

  • macaddr — the MAC Address, used as the base key. like, it's the raw material, the ~source material~ of the whole operation. six bytes of pure potential. 💖

⭐ DESCRIPTION ⭐

ok so what does it do? bestie it simply copies the address and returns it as a u64 for hashing. that's the entire plot. no twists, no side quests, no sneaky allocation — just copy and return. it's giving "small function, big confidence". 🧚

ngl it's kind of iconic how little it does. a humble little hash-key factory. 🔥
