i40e_vc_process_vf_msg(9)

📦 version 7.3.1, in nixpkgs unstable

✨ i40e_vc_process_vf_msg ✨

okay so bestie, welcome to i40e_vc_process_vf_msg(9) — yes, that's the whole name, it's from the Kernel API Manual, and no I will not be shortening it 💅

💖 NAME 💖

i40e_vc_process_vf_msg —

and that's it. that's the whole NAME section. the description part is literally empty. not me getting ghosted by the manpage 😭 it's giving "left on read" energy fr fr. anyway, keep scrolling, the rest is juicy.

🌸 SYNOPSIS 🌸

int i40e_vc_process_vf_msg (struct i40e_pf *pf , s16 vf_id , u32
v_opcode , u32 v_retval , u8 *msg , u16 msglen );

copy that exactly, spacing and all — she has a specific look and we respect it 🎀

🦋 ARGUMENTS 🦋

six whole arguments, bestie, and every single one matters:

  • pf — pointer to the PF structure 👑 that's the main character right there, the physical function itself
  • vf_id — the source VF id 🔍 like, who is this message even from
  • v_opcode — the operation code ⚙️ the "what are we doing" of it all
  • v_retval — an unused return value code 🙈 literally does nothing, it's just vibing in the parameter list, no cap
  • msg — pointer to the msg buffer 💌 where the actual message lives
  • msglen — the msg length 📏 so we know how much of that buffer is real

🧚 DESCRIPTION 🧚

so what does she do? she's called from the common aeq/arq handler to process request from VF ✨

that's the whole description, and honestly? iconic. she takes requests from the VF, that's her job, that's her purpose, that's her main character energy 💅 the aeq/arq handler calls her, she handles the VF's request, done. periodt.

🔥 SEE ALSO 🔥

first up, the source file she lives in — Kernel file ./drivers/net/ethernet/intel/i40e/i40e_virtchnl_pf.c 📁 home sweet home.

and now... the friend group. bestie this is the longest SEE ALSO I've ever seen, she knows everybody in the i40e universe. here's the full squad, in order, no one left out 🫶

like, ninety-five whole entries. she's not just networked, she's the network 🌈 iykyk.

ngl bestie, this page is short but she's got range — a whole VF request pipeline in like one sentence of description. lowkey obsessed 🍓

and that's the whole thing!! 🎀 written in the ./drivers/net/ethernet/intel/i40e directory, dated October 2026, and forever known as i40e_vc_process_vf_msg(9) 💜 go forth and process those VF messages, bestie — slay ✨💅🦋
