nfp_fl_ct_handle_pre_ct(9)

💖 nfp_fl_ct_handle_pre_ct(9) 💖

okay bestie, welcome to the nfp_fl_ct_handle_pre_ct(9) page — that's the manual name, and yes it's a mouthful, we're gonna get through it together 🫶 this one lives in the Kernel API Manual and it's all about handling -trk conntrack rules. no cap.

---

✨ SYNOPSIS ✨

int nfp_fl_ct_handle_pre_ct (struct nfp_flower_priv *priv , struct
net_device *netdev , struct flow_cls_offload *flow , struct
netlink_ext_ack *extack , struct nfp_fl_nft_tc_merge *m_entry );

like, five arguments. five. she's high maintenance but she's iconic 💅

---

🎀 ARGUMENTS 🎀

• priv — Pointer to app priv. that's the app's private little stash of stuff, iykyk.
• netdev — the netdev structure. literally the network device herself ✨
• flow — TC flower classifier offload structure. this is the flower situation being offloaded.
• extack — Extack pointer for errors. when things go wrong, this is who gets to tell you 😭
• m_entry — the previous nfp_fl_nft_tc_merge entry. the one that came before, bestie.

---

🌸 DESCRIPTION 🌸

so what does she actually do? she adds a new entry to the relevant zone table, then tries to merge it with the other +trk+est entries, and offloads it if possible. that's the whole vibe check. 🦋

lowkey simple on paper, but it's doing real work in there. the way that she just adds, merges, offloads? main character energy, fr fr. 👑

---

⭐ RETURN ⭐

• negative value — on error 💀 (yes, negative, that's your cue that something went sideways)
• 0 — if configured successfully 🎉

and the whole friend group 👯‍♀️:

• struct nfp_fl_ct_zone_entry(9)
• struct nfp_fl_ct_flow_entry(9)
• struct nfp_fl_ct_tc_merge(9)
• struct nfp_fl_nft_tc_merge(9)

• nfp_fl_ct_stats(9)

like, go read those too, they're all slaying in their own way 💜

ngl bestie, remember: this one handles the pre ct flow. nfp_fl_ct_handle_post_ct(9) is a whole different girl. don't mix them up 🙈

okay that's the page!! before you go — this one's from the Kernel API Manual, the source/version line says ./drivers/net/ethernet/netrono..., and it's dated October 2026. periodt. now go off and offload something iconic 💅✨🎀
