💅 nfp_fl_ct_handle_post_ct — Kernel API Manual, bestie edition

okay so this is a page straight out of the Kernel API Manual (yes, that's the manual name, it's giving very official energy ✨) and we're talking about nfp_fl_ct_handle_post_ct — say that five times fast, I dare you 🫶

---

🌸 NAME 🌸

nfp_fl_ct_handle_post_ct — handles those +trk+est conntrack rules, and yes the plus signs are part of the vibe, do not touch them 💅

---

✨ SYNOPSIS ✨

int nfp_fl_ct_handle_post_ct (struct nfp_flower_priv *priv , struct
       net_device *netdev , struct flow_cls_offload *flow , struct
       netlink_ext_ack *extack );

lowkey a whole signature, and we're keeping it exactly like that, character for character, no cap 🔥

---

🎀 ARGUMENTS 🎀

these are the four besties that show up to the function:

• priv — a pointer to app priv. that's it, that's the whole description, she's mysterious and we respect it 🙈
• netdev — the netdev structure. the moment the network device walks in 💫
• flow — the TC flower classifier offload structure. iconic, main character energy 👑
• extack — the extack pointer for errors. she's the one holding the receipts when something goes wrong 😭

---

🦋 DESCRIPTION 🦋

so what does she actually do? simple, bestie:

she adds a new entry to the relevant zone table, then tries to merge it with the other -trk entries, and offloads if possible. ✨

that's the whole arc. entry → merge attempt → maybe offload. periodt 🌈

---

⭐ RETURN ⭐

• a negative value on error 💀
• 0 if it configured successfully 🎉

iykyk — check your return value, always 🫶
