ixgbe_set_mac(9)

📦 version 7.3.1, in nixpkgs unstable

💅 NAME 💅

ixgbe_set_mac — change the Ethernet Address of the NIC

okay so real talk, this is a page out of the Kernel API Manual (section 9, kernel-dev territory, very main-character of it) and it's about exactly one little function. let's go 🦋

✨ SYNOPSIS ✨

int ixgbe_set_mac (struct net_device *netdev , void *p );

that's the whole vibe. two args, one int coming back at you. no cap.

🎀 ARGUMENTS 🎀

  • netdev — the network interface device structure 💖 this is the NIC's whole little identity card, the thing you're swapping the address on
  • p — a pointer to an address structure 🌸 like, it points at the address, it doesn't contain it, it points at it, iykyk

🔥 DESCRIPTION 🔥

here's the tea, and it's short and sweet:

  • Returns 0 on success 🫶
  • negative on failure 😭

and that's literally it. that's the whole description. not me expecting a whole saga and getting two clauses. iconic honestly, she said "read the source bestie" 😌

👑 SEE ALSO 👑

first up, the kernel file where this lives, fr fr:

  • Kernel file ./drivers/net/ethernet/intel/ixgbe/ixgbe_main.c

and then the friend group. this is a long list. i'm not skipping a single one of them because they're all part of the family 💜

like i said. the whole friend group. say hi to all 118 of them or whatever 😭💀

okay that's the page!! source/version vibe is ./drivers/net/ethernet/intel/i... and it's dated October 2026 🌸 so jot that down, and remember: 0 means slay, negative means not slay. bye bestie 💖✨🎀🦋
