i40e_ndo_set_vf_mac(9)

💅 i40e_ndo_set_vf_mac 💅

okay so this little cutie lives in the Kernel API Manual (section 9, iykyk) and bestie, it is short. Like, suspiciously short. We're talking a NAME line with literally nothing after the dash. No tagline. No elevator pitch. She's mysterious. She's giving minimal effort main character energy and honestly? Respect. 🎀

✨ NAME ✨

i40e_ndo_set_vf_mac — and that's it. That's the whole name section. The description after the dash is empty, no cap. Not me refreshing the page waiting for more 😭. She said "my name is enough."

---

🌸 SYNOPSIS 🌸

int i40e_ndo_set_vf_mac (struct net_device *netdev , int vf_id , u8 *mac
);

yes the ); is on its own line, that's just how the manpage generator woke up that day, don't come for her 💀. Keep it exactly like this if you're quoting it, bestie — character for character, fr fr.

---

🦋 ARGUMENTS 🦋

Three of them. Three little besties walk into a function:

• netdev — the network interface device structure 🫶 this is the NIC-shaped homegirl the whole thing is about.
• vf_id — the VF identifier ✨ which Virtual Function we're talking to, by number.
• mac — the mac address 👑 (a u8 *, so it's a pointer, don't @ me).

---

💖 DESCRIPTION 💖

program VF mac address

that's the whole description. one line. lowercase. no period. she ate and left zero crumbs 🍓. Technically what's happening: this is the business end that programs a Virtual Function's MAC address. That's the vibe, that's the assignment, periodt. 💅

ngl if you came here looking for a novel, this manpage is a haiku. The details are all up in the SEE ALSO though — she may be quiet but her friend group is enormous. 🔥
