i40e_ndo_set_vf_spoofchk(9)

💅 i40e_ndo_set_vf_spoofchk(9) — from the Kernel API Manual, bestie

okay so this one is from the Kernel API Manual, and it's giving "tiny function, big friend group" energy. it's a netdev callback for the i40e driver — the Intel ethernet thing — and it's literally the thing that toggles VF spoof checking on or off. that's it. that's the whole vibe. ✨

🌸 NAME 🌸

i40e_ndo_set_vf_spoofchk — and honestly? the NAME section in the original is just the function name and then nothing. no blurb. no little summary. the man page said "she's mysterious" and moved on 💀 so like, respect, but also rude. the actual description lives down in DESCRIPTION, keep reading bestie.

---

🎀 SYNOPSIS 🎀

int i40e_ndo_set_vf_spoofchk (struct net_device *netdev , int vf_id ,
bool enable );

that's the whole signature. three args in, an int out. she's concise, she's iconic, she ate 🫶

---

🦋 ARGUMENTS 🦋

here's the cast of characters, no cap:

• netdev — the network interface device structure. like, the actual net device we're talking about. main character energy right here 👑
• vf_id — the VF identifier. which virtual function are we messing with? that's this number, bestie 🔢
• enable — a flag to enable or disable the feature. true-ish means on, false-ish means off. it's a bool, so it's literally just "yes bestie" or "no bestie" 🙈

---

✨ DESCRIPTION ✨

Enable or disable VF spoof checking. that is, word for word, the entire description in the original. she's short. she's to the point. she doesn't over-explain. genuinely obsessed with the minimalism ngl 💅

so yeah — the function's whole job: take the netdev, take a VF id, take an enable flag, and flip VF spoof checking on or off accordingly. periodt. 🎯
