💅 iavf_fill_fdir_ip4_hdr(9) 💅

okay so bestie, this one's from the Kernel API Manual and it's honestly such a little icon — a whole function whose entire personality is "fill the IPv4 protocol header" and then dip. we love a focused queen 🎀

✨ NAME ✨

iavf_fill_fdir_ip4_hdr — fill the IPv4 protocol header. that's it, that's the job, and she does it 🫶

🌸 SYNOPSIS 🌸

int iavf_fill_fdir_ip4_hdr (struct iavf_fltr *fltr , struct
       virtchnl_proto_hdrs *proto_hdrs );

like, she takes two structs and hands you back an int. simple. elegant. no cap ✨

🦋 ARGUMENTS 🦋

  • fltr — the Flow Director filter data structure 💖 this is the main character, the filter data itself
  • proto_hdrs — the Flow Director protocol headers data structure 🌈 this is where the protocol headers live

👑 DESCRIPTION 👑

Returns 0 if the IPv4 protocol header is set successfully 🎉 that's literally the whole contract — you call her, she fills the header, she gives you a 0 back, everyone's happy, periodt 💅

ngl bestie, the manpage doesn't say what comes back when it doesn't succeed, so don't go inventing meanings for other return values — she didn't say, so we don't say 🙈

⭐ SEE ALSO ⭐

first up, the source herself — the kernel file:
