✨ i40e_reset_all_vfs — Kernel API Manual energy 💅

Okay bestie, buckle up, because this one is a little kernel-side baddie from the Kernel API Manual, and you're gonna get it on the first read, iykyk 🎀

💖 NAME

So the original page is literally just:

i40e_reset_all_vfs -

and then nothing. A whole dash. Iconic of it, honestly 🫶 — no one-line summary was given, so I'm not gonna invent one for you. What I can tell you is the function's name is i40e_reset_all_vfs, and the actual what-it-does lives down in DESCRIPTION. Keep scrolling 🌸

✨ SYNOPSIS

Here's the whole signature, copy-pasted exactly so you know it's fr fr:

bool i40e_reset_all_vfs (struct i40e_pf *pf , bool flr );

Two args, one bool coming back at you. That's the whole vibe 🌈

🦋 ARGUMENTS

  • pf — a pointer to the PF structure. Yes, PF, as in the physical function, the main-character of this whole file 👑
  • flr — tells you whether a VFLR was issued or not. That's it, that's the flag 🎀

🔥 DESCRIPTION

Okay so the assignment here is: reset all allocated VFs in one go. No serialized drip-feed, no one-at-a-time nonsense 💀

The way it goes down, in order:

  1. First, tell the hardware to reset each VF.
  2. Then do all the waiting in one single chunk — one big wait, not a million tiny ones ⭐
  3. Finally, finish restoring each VF after the wait.

Why is this a slay? Because during PF routines that need to reset all VFs, this is the move — otherwise you'd have to perform these resets in a serialized fashion, one after another, which is lowkey giving "waiting in line at the DMV" 🙈 This function ate and left no crumbs.

Returns true if any VFs were reset, and false otherwise. That's the return contract, no cap 💜

🌸 SEE ALSO

The source file it lives in, bestie:

  • ./drivers/net/ethernet/intel/i40e/i40e_virtchnl_pf.c

And here's the entire crew of related kernel API pages, in the exact order the original lists them — all 95 of them, because I would never do you dirty like that 💅

And that's the whole page, bestie 🧚 Go forth and reset those VFs, and remember: hardware first, wait once, restore after. Periodt. 💜

Mwah 💋 — this cutie came from the ./drivers/net/ethernet/intel/i40e source, dated October 2026, and yes the page is literally named i40e_reset_all_vfs(9) in case you forgot already 😭
