i40e_config_irq_link_list(9)

💅 i40e_config_irq_link_list(9) — the kernel api manual, but make it make sense

okay so bestie, welcome to the Kernel API Manual ✨ and specifically to section 9 of it, where we're gonna talk about one very specific little function called i40e_config_irq_link_list. she's a void, she's a network driver girlie, she lives in the Intel i40e world, and honestly? she ate. let's get into it 🎀

---

✨ NAME ✨

i40e_config_irq_link_list — and that's literally it, that's the whole name section 😭 the original page gives her no cute one-liner tagline, no subtitle, nothing. mysterious main character energy. we respect it. 💅

---

🌸 SYNOPSIS 🌸

the whole vibe, verbatim, no notes:

void i40e_config_irq_link_list (struct i40e_vf *vf , u16 vsi_id , struct
virtchnl_vector_map *vecmap );

so she returns void (nothing back, she gives and doesn't take 💖) and she takes three lil friends. yes the spacing with vf , is exactly like that, don't come for me, I don't make the rules 🫶

---

🦋 ARGUMENTS 🦋

every single one, bestie, we're not skipping anyone:

• vf — a pointer to the VF info 👑 like, the whole scoop on that virtual function. pointer energy.
• vsi_id — the id of the VSI, as given by the FW. that's the firmware handing you the id, so it's not you, it's her ✨
• vecmap — the irq map info 🌈 the map, the layout, the whole situation, handed to you in a struct virtchnl_vector_map *.

---

💜 DESCRIPTION 💜

okay so the actual job description is literally one line and it's this: configure irq link list from the map. that's it. that's the tea ☕ she takes the map and she configures the irq link list from it. short, sweet, does exactly one thing and does it well. lowkey iconic. periodt 💀✨

ngl bestie, this page is a short one — no options, no exit statuses, no env vars, no warnings. just a function doing her little job from the map. sometimes that's enough 🎀
