ice_flow_assoc_fdir_prof(9)

📦 version 7.3.1, in nixpkgs unstable

💅 ice_flow_assoc_fdir_prof(9) — like, the kernel API manual page, bestie ✨

okay so you found your way into the ice driver docs, iconic of you honestly 🫶 this one's from the Kernel API Manual, section 9 — buckle up, it's a short one but it matters.

🌸 NAME 🌸

ice_flow_assoc_fdir_prof — adds an FDIR profile for the main/ctrl VSI. that's the whole vibe. no cap 💖

⭐ SYNOPSIS ⭐

int ice_flow_assoc_fdir_prof (struct ice_hw *hw , enum ice_block blk ,
       u16 dest_vsi , u16 fdir_vsi , u64 hdl );

literally just copy that exactly, don't @ me 🙈

🎀 ARGUMENTS 🎀

  • hw — pointer to the HW struct. yes the big one. the hardware-y one 💅
  • blk — HW block. which block? the block. (enum ice_block, bestie, it's typed)
  • dest_vsi — dest VSI. the destination virtual station interface, the one getting the glow-up ✨
  • fdir_vsi — fdir programming VSI. this is the VSI doing the FDIR programming, lowkey the main character here 👑
  • hdl — profile handle. it's a u64, it's a handle, it points at a profile. iykyk

🦋 DESCRIPTION 🦋

so what does it actually do? it updates the hardware tables to enable the FDIR profile indicated by hdl for the VSI specified by dest_vsi. and on success, the flow will be enabled. that's it. that's the tea 🍓

like — profile goes in, tables get updated, flow comes out enabled. slay 🔥

💀 RETURN 💀

0 on success or negative errno on failure. so if you get a negative number back, that's your sign, it's giving error, check your errno bestie 😭

🌈 SEE ALSO 🌈

first up, the source file lives right here:

Kernel file ./drivers/net/ethernet/intel/ice/ice_flex_pipe.c

and now the entire friend group — every single one of these, no skipping, we don't do that here 💜:

like, that's a lot of friends. they all ate. periodt 🧚

ngl, this is a kernel internal, so don't go calling it from userspace and acting surprised when it doesn't work 🙈

okay that's the page!! and since we're being thorough, the cute little sign-off at the bottom of the original says this all comes from ./drivers/net/ethernet/intel/ice and it's dated October 2026 — so yeah, mark your calendar, bestie, that's the version era 💖✨🎀 see u in section 9 🦋
