iavf_add_cls_u32(9)

📦 version 7.3.1, in nixpkgs unstable

🦋 NAME 🦋

okay bestie, welcome to the Kernel API Manual, section 9 — this is iavf_add_cls_u32, and she's here to add U32 classifier offloads 💅

Like, that's literally the whole vibe: iavf_add_cls_u32 — Add U32 classifier offloads. No cap.

✨ SYNOPSIS ✨

int iavf_add_cls_u32 (struct iavf_adapter *adapter , struct tc_cls_u32_offload *cls_u32 );

so she takes two pointers and gives you back an int. that's it, that's the girl 🎀

🌸 ARGUMENTS 🌸

  • adapter — pointer to iavf_adapter structure. yep, the whole adapter, she needs the context, main character energy only 🫶
  • cls_u32 — pointer to tc_cls_u32_offload struct with flow info. this one's carrying the actual flow details, so like… don't leave it empty, i'm begging 😭

⭐ RETURN ⭐

0 on success, or a negative errno on failure. so if you get 0, slay — you ate. if it's negative, that's your villain origin story, go read the errno 💀
