i40e_create..._sctp_packet(9)

💖 i40e_create_dummy_sctp_packet — the SCTP packet-building bestie 💖

okay so real talk, this page lives in the Kernel API Manual, section 9, and honestly? it's a tiny little helper doing tiny little helper things and I'm obsessed 🫶

✨ NAME ✨

i40e_create_dummy_sctp_packet — a helper function to create an SCTP packet, no cap 💅

---

🌸 SYNOPSIS 🌸

void i40e_create_dummy_sctp_packet (u8 *raw_packet , bool ipv4 , u8
l4proto , struct i40e_fdir_filter *data );

like… it returns void. it does the thing and dips. main character energy honestly 👑

---

🎀 ARGUMENTS 🎀

• raw_packet — preallocated space for the dummy packet. you bring the buffer, she brings the packet 🍓
• ipv4 — is the layer 3 packet version 4 or version 6? yes/no bestie, that's the whole vibe check 🌈
• l4proto — the next level protocol used in the data portion of l3 🦋
• data — filter data 💜

---

🧚 DESCRIPTION 🧚

so what does she actually do? she's a helper function to populate SCTP fields. that's it. that's the whole gig. iconic, focused, doesn't overexplain 💖
