idpf_set_mac(9)

💅 idpf_set_mac — a Kernel API Manual moment (section 9, bestie)

okay so welcome to idpf_set_mac, straight out of the kernel API manual (that's the 9 in the corner, iykyk — kernel devs get their own section, main character energy fr). This is the NDO callback that sets the port MAC address. Yes, that kind of callback. Networking girlies know. 🦋

---

✨ SYNOPSIS ✨

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

that's it. that's the whole vibe. two args and a return value. slay. 💅

---

🎀 ARGUMENTS 🎀

• netdev — the network interface device structure. this is the netdev bestie in question, the whole reason we're here 💖
• p — a pointer to an address structure. that's literally what the manpage says and honestly? respect the mystery 🫶

---

🌸 DESCRIPTION 🌸

returns 0 on success, and a negative value on failure. periodt. that's the description. no cap, no extra lore, that's genuinely the whole thing 💀 — success = 0, failure = negative. memorise it, it comes up.

lowkey iconic how a whole NDO callback has a shorter description than my last text message, but we move 😭

mwah 💜 that's the page! it lives over in ./drivers/net/ethernet/intel/idpf, and this particular slice of kernel lore is dated October 2026. go set some MAC addresses (the port ones, via the NDO callback, obviously). bye bestie 🎀✨🌸
