i40e_program_fdir_filter(9)

📦 version 7.3.1, in nixpkgs unstable

💖 i40e_program_fdir_filter — from the Kernel API Manual (kernel land's own little bible) 💖

okay so bestie, gather round, because this one is a whole function and she does exactly one (1) job: programming a Flow Director filter. that's it, that's the vibe. no cap. 🎀

✨ NAME ✨

i40e_program_fdir_filter — literally programs a Flow Director filter. that's the whole personality. 💅

🌸 SYNOPSIS 🌸

int i40e_program_fdir_filter (struct i40e_fdir_filter *fdir_data , u8 *raw_packet , struct i40e_pf *pf , bool add );

like, she returns an int, she takes four things, and she is serving. 🔥

🦋 ARGUMENTS 🦋

  • fdir_data — the packet data that's gonna become your filter parameters. this is the main character of the operation, honestly. 👑
  • raw_packet — the pre-allocated packet buffer for FDir. it's already sitting there waiting for you, no allocations needed, we love a prepared queen. ✨
  • pf — The PF pointer. yes, capital T capital P capital F, respect her. 🫶
  • add — True for add/update, False for remove. binary queen, two moods only: put it in or take it out. 💀
