💅 iavf_validate_fdir_fltr_masks(9) — the Kernel API Manual cut

okay so bestie, welcome to the Kernel API Manual, section 9, and today's main character is iavf_validate_fdir_fltr_masks 🎀 (the header truncates it to iavf_valida...r_fltr_masks(9) which is lowkey tragic but we move).

✨ NAME ✨

iavf_validate_fdir_fltr_masks — she validates Flow Director filter fields masks. that's it, that's the job 🫶

🌸 SYNOPSIS 🌸

int iavf_validate_fdir_fltr_masks (struct iavf_adapter *adapter , struct iavf_fdir_fltr *fltr );

🦋 ARGUMENTS 🦋

  • adapter — pointer to the VF adapter structure. literally just a pointer to your VF adapter struct, nothing spicy 💜
  • fltr — the Flow Director filter data structure. this is the filter bestie we're checking 🌈

💖 DESCRIPTION 💖

okay so here's the vibe check 👑: she returns 0 if all masks of packet fields are either full or empty. that's a pass, we love that for her ✨

but if there's at least one partial mask?? returns error. not full, not empty, just... partial 😭 partial masks are not the moment, and she will absolutely call it out 💀

fr fr no partial masks allowed — it's full or empty or nothing, periodt 💅
