💖 ice_vc_fdir_set_flow_hdr(9) — NAME 💖

okay so bestie, welcome to the Kernel API Manual ✨ and buckle up, because this function is literally called ice_vc_fdir_set_flow_hdr and it does exactly one iconic thing: it configs the flow's packet segment header. that's it, that's the whole vibe. no cap. 🎀

🌸 SYNOPSIS 🌸

int ice_vc_fdir_set_flow_hdr (struct ice_vf *vf , struct
       virtchnl_fdir_fltr_conf *conf , struct ice_flow_seg_info *seg );

three structs walk into a function and return an int, iykyk 💅

🦋 ARGUMENTS 🦋

  • vf — a pointer to the VF structure. yes, the VF. hi bestie 👋
  • conf — the FDIR configuration for each filter. one config per filter, she's organized fr fr 💖
  • seg — an array of one or more packet segments that describe the flow. so like, a whole lineup of segments, not just one. she can bring friends 🫶

👑 RETURN 👑

0 on success, and other on error. that's it. zero = slay, anything else = not slay 😭

ngl the manpage says "and other on error" verbatim, so that's what you get. she's a little vague but she's honest 💀
