iavf_set_mac(9)

🎀 iavf_set_mac(9) 🎀

okay so bestie, welcome to the kernel API manual for iavf_set_mac — yes that's the iavf_set_mac(9) page, the one and only. it's a NDO callback to set port MAC address and honestly? it's giving main character energy in the iavf driver. sit down, grab a strawberry drink, we're doing this 💖

---

✨ NAME ✨

iavf_set_mac — the NDO callback that sets the port MAC address. that's it, that's the whole job, and she does it 💅

---

🌸 SYNOPSIS 🌸

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

like literally just that. two arguments, one int out the other side. no cap 🫶

---

🦋 ARGUMENTS 🦋

• netdev — the network interface device structure. the whole net device, the icon, the moment. she's the one getting a new MAC address ✨
• p — a pointer to an address structure. that's where the new address is chillin' before it gets applied 🙈

---

🔥 DESCRIPTION 🔥

Returns 0 on success, negative on failure. that's the entire description bestie, i'm not gonna pad it out and lie to you. 0 = slay, negative = 😭.

fr fr, that's all the manpage says. no extra lore, no behind-the-scenes, so i'm not gonna invent any. iykyk.
