dpni_set_primary_mac_addr(9)

📦 version 7.3.1, in nixpkgs unstable

💅 dpni_set_primary_mac_addr — from the Kernel API Manual, bestie

Okay so real talk, this is dpni_set_primary_mac_addr(9) and yeah, the name is a whole mouthful but it's lowkey doing exactly what it says on the tin. We're setting a network interface's main-character MAC address. That's it. That's the whole vibe. ✨

🌸 NAME

dpni_set_primary_mac_addr — sets the primary MAC address. Iconic, straightforward, no notes.

🎀 SYNOPSIS

int dpni_set_primary_mac_addr (struct fsl_mc_io *mc_io , u32 cmd_flags ,
u16 token , const u8 mac_addr[6] );

Like, look at her. Four args, returns an int, does the thing. Obsessed. 💖

🦋 ARGUMENTS

  • mc_io — Pointer to MC portal's I/O object. This is your little handle into the management complex, don't lose it, she's important 🫶
  • cmd_flags — Command flags; one or more of 'MC_CMD_FLAG_'. Yes, it's one of those bitmask situations, iykyk.
  • token — Token of DPNI object. Your lil' ticket that says "yeah that DPNI, the one right there" 🎟️
  • mac_addr — MAC address to set as primary address. It's a const u8 mac_addr[6] — six bytes, exactly six, no more no less, periodt 💀

⭐ RETURN

The page literally doesn't spell it out, bestie — the int return is just sitting there in the synopsis being mysterious. That's the whole story, no cap. 🙈

🔥 SEE ALSO

Alright, buckle up, because this list is LONG and honestly kind of iconic. Every single one of these, exactly as written:

💜 Little sign-off moment: this page comes from that very kernel source path (./drivers/net/ethernet/freesca... in the footer, bestie, they truncated it, not me), dated October 2026. Slay, documented, periodt. 🌈👑
