i40e_config_vsi_rx_queue(9)

📦 version 7.3.1, in nixpkgs unstable

💅 i40e_config_vsi_rx_queue — Kernel API Manual 💅

okay bestie, welcome to the Kernel API Manual, the (9) section, where we hang out with the i40e driver 🦋 this one's a lil function from the Intel NIC corner of the kernel and honestly she's a whole vibe. lowkey short page, highkey useful. let's get into it ✨

✨ NAME ✨

i40e_config_vsi_rx_queue

that's it. that's the name 🎀 the original page throws a dash after it and then... nothing. no one-liner, no description, the man page author simply left it blank. not me noticing the empty description 💀 so we're just going with the function name itself, periodt.

🌸 SYNOPSIS 🌸

int i40e_config_vsi_rx_queue (struct i40e_vf *vf , u16 vsi_id , u16 vsi_queue_id , struct virtchnl_rxq_info *info );

she returns an int, she takes four things, and yes the spacing is giving "authored by C programmers at 3am" 😭 we keep it exactly as it is, no cap 🫶

🧚 ARGUMENTS 🧚

  • vf — pointer to the VF info 💖 like, the virtual function we're talking about? this is her.
  • vsi_id — id of VSI as provided by the FW ⭐ fair warning: as provided by the FW, so whatever the firmware handed you, that's what you pass. don't be out here inventing your own.
  • vsi_queue_id — the vsi relative queue index 🎀 relative to the VSI, bestie. not global. not absolute. relative.
  • info — config. info 🔥 that's genuinely the whole description. config. info. iconic brevity.

👑 DESCRIPTION 👑

configure rx queue 💅

that's it. that's the whole description. four words. the man page said what it said and left. ngl there's something so main-character about a description that refuses to elaborate 🙈

so: this function configures the receive queue. that's the fact. everything else? (gestures vaguely at the driver source) iykyk ✨

🌈 SEE ALSO 🌈

kay this section is long and she ate, so buckle up bestie, every single reference is coming with us 🦋

the kernel file where all this lives:

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

and the entire friend group 💖:

like i said: the whole friend group 🌸 go read them, they're all in the same file and they're all doing the most 💜

real talk though — the arguments have to be the ones the firmware gave you (vsi_id is as provided by the FW, remember 🎀) and vsi_queue_id is VSI-relative. don't mix those up or it's giving "why is my rx broken" 😭

okay that's the page!! mwah 💖 this little beauty lives in ./drivers/net/ethernet/intel/i40e, and the page is dated October 2026 — so like, future girl summer 🌈✨ go configure that rx queue bestie, you've got this 👑🫶
