idpf_sriov_ena(9)

✨ idpf_sriov_ena(9) ✨

okay so bestie, we're deep in the kernel API manual today — this one's idpf_sriov_ena(9), and honestly? it's giving "small function, big responsibilities" energy. it lives down in ./drivers/net/ethernet/intel/idpf/ and it's here to get your virtual functions (VFs) turned on or resized. let's get into it 🫶

---

💖 NAME 💖

idpf_sriov_ena — enable or change the number of VFs. that's it, that's the whole vibe. one job, done iconically 💅

---

🌸 SYNOPSIS 🌸

int idpf_sriov_ena (struct idpf_adapter *adapter , int num_vfs );

not me just casually dropping the exact signature up there — copy it character for character, no freestyling 😌

---

🦋 ARGUMENTS 🦋

• adapter — the private data struct. she's the one carrying all the state, the main character of the adapter world 👑
• num_vfs — how many VFs you wanna allocate. yes, this is a number, please pass a sane one 💀

🎀 SEE ALSO 🎀

first up, the actual source, if you wanna read the lore yourself:

like… the way that's an entire friend group 😭 every single one gets a lil shoutout, iykyk.

ngl the only thing this page asks of you is the adapter and the num_vfs — no extra options, no flags, no environment variables, no exit statuses hiding in the fine print. what you see is what you get, periodt 💜

and that's the page, bestie!! 🌈 this lil legend comes from ./drivers/net/ethernet/intel/idpf, October 2026 edition — go forth and enable those VFs responsibly ✨🎀🦋
