ipa_route_tuple_zero(9)

🦋 ipa_route_tuple_zero(9) 🦋

okay so bestie, welcome to the Kernel API Manual — this one's a lil function page and it's lowkey iconic in the most niche way possible. we're talking ipa_route_tuple_zero, and no I will not be pronouncing it out loud. it's a kernel function, it lives in the IPA world, and it does exactly one thing. main character energy, honestly.

✨ NAME ✨

ipa_route_tuple_zero — zero a hashed route table entry tuple 💅

like, that's it. that's the whole job. it zeroes a tuple. in the route table. hashed. periodt.

---

🌸 SYNOPSIS 🌸

void ipa_route_tuple_zero (struct ipa *ipa , u32 route_id );

not me copy-pasting this exactly because the spacing is literally part of the vibe. those spaces before the commas? iconic. leave them alone. 🫶

🎀 ARGUMENTS 🎀

• ipa — the IPA pointer. just… the IPA. she's here, she's a pointer, she's struct ipa *. that's the whole description, ngl. 💖
• route_id — the route table entry whose hash tuple should be zeroed. yes bestie, that one. the one you're zeroing. go off. 🔥

---

⭐ DESCRIPTION ⭐

so here's the tea: this function updates the route hash values without changing the filter ones. that's the whole bit. that's the assignment. route hash values get updated, filter values stay exactly where they are, untouched, unbothered, living their best life. 🧚

fr fr, this is one of those "small function, big responsibility" situations — the caveat here is just the scope: route tuple gets zeroed, filter tuple does NOT. don't go assuming otherwise. 😭

👑 SEE ALSO 👑

• Kernel file ./drivers/net/ipa/ipa_table.c — the whole IPA Filter and Route Tables(9) situation lives here, iykyk ✨
• ipa_filter_tuple_zero(9) — the sibling function. the other half of the duo. the filter to this route. 💜

🌈 and that's the page!! if you made it this far you're literally a kernel dev now, congrats. 🎀

this lil sign-off comes to you from ./drivers/net/ipa, dated October 2026 — yeah, from the future, no cap. slay. 💅🦋
