i40e_create_...y_tcp_packet(9)

💅 NAME 💅

i40e_create_dummy_tcp_packet — bestie, it's the helper function that creates a TCP packet ✨

(Also hi, you're reading the Kernel API Manual, welcome to the i40e cinematic universe 🎀)

---

🦋 SYNOPSIS 🦋

void i40e_create_dummy_tcp_packet (u8 *raw_packet , bool ipv4 , u8
l4proto , struct i40e_fdir_filter *data );

---

🌸 ARGUMENTS 🌸

• raw_packet — preallocated space for the dummy packet, like the venue is already booked, you just gotta show up 💖
• ipv4 — is the layer 3 packet version 4 or 6? yes/no, pick a lane babes
• l4proto — the next-level protocol used in the data portion of l3, iykyk
• data — the filter data, it's giving main character energy honestly

---

✨ DESCRIPTION ✨

Okay so, plot twist: it's a helper function to populate TCP fields. That's the whole vibe. It fills in the TCP parts for you so you don't have to, and honestly? Obsessed. 🫶

🧚 And that's the whole read, bestie — go forth and populate those TCP fields, slay 💜

Okay so this absolute icon of a page lives at ./drivers/net/ethernet/intel/i40e, and it dropped way back in October 2026 — periodt. Now go touch some grass, or at least go read the actual kernel file ./drivers/net/ethernet/intel/i40e/i40e_txrx.c. 🍓👑
