📦 version 7.3.1, in nixpkgs unstable

💖 i40e_validate_vf(9) 💖

Kernel API Manual, bestie — yes, we're doing kernel lore today. ✨

🌸 NAME 🌸

i40e_validate_vf -

That's the name and the dash, periodt. The original blurb after the dash is literally empty, so we're not inventing a summary. 💅

✨ SYNOPSIS ✨

Here's the signature, exactly as it appears — don't let the spacing jump you:

int i40e_validate_vf (struct i40e_pf *pf , int vf_id );

🎀 ARGUMENTS 🎀

  • pf — the physical function. That's the PF, the main-character struct here.
  • vf_id — VF identifier. Basically which VF we're pointing at, bestie.

🦋 DESCRIPTION 🦋

Okay so what does it actually do? It checks that the VF is enabled and that the VSI exists. That's the whole vibe check. 💖

It returns 0 on success, and negative on failure. No cap: zero is the good ending, negative means nope.
