🌸 i40e_add_del_fdir — Kernel API Manual 🌸

okay so bestie, welcome to the i40e_add_del_fdir(9) page 💖 this is a kernel API manual (yes, the kernel, we're in the big leagues now) and it's genuinely so much less scary than it looks. sit down, grab a strawberry drink 🍓, and let's get into it.

✨ NAME ✨

i40e_add_del_fdir — build raw packets to add/del fdir filter 🎀

like… that's the whole vibe. it builds raw packets so you can add or delete an fdir filter. no cap.

---

🦋 SYNOPSIS 🦋

int i40e_add_del_fdir (struct i40e_vsi *vsi , struct i40e_fdir_filter
*input , bool add );

yes the spacing is Like That, copy it exactly, don't come for me 💅

---

💜 ARGUMENTS 💜

three little besties walk into a function:

• vsi — pointer to the targeted VSI 👑 this is the VSI we're aiming at, it's the main character of this call.
• input — filter to add or delete 🎯 the actual filter object being added or removed.
• add — true adds a filter, false removes it ✨ literally that simple, it's giving on/off switch energy. true = add, false = del, periodt.

and that's the page!! you ate that 🫶 mwah 💋

sign-off time 🎀 this gorgeous little page ships from ./drivers/net/ethernet/intel/i40e, dated October 2026, and it's page i40e_add_del_fdir(9) of the Kernel API Manual — iconic, no notes, periodt ✨💖
