STRUCT IDPF_VECTOR_INFO(9)

💅 struct idpf_vector_info(9) 💅

okay so this is a page straight out of the Kernel API Manual (section 9, bestie, we're in the kernel docs now 🔥) and it's about struct idpf_vector_info — a literal utility structure whose whole entire job is to pass function arguments as a structure. that's it. that's the gig. she's a little carrier pigeon for your args 🕊️✨

🎀 NAME 🎀

struct idpf_vector_info — a utility structure to pass function arguments as a structure 💖

like, she doesn't do anything, she just holds things. main character energy, honestly 👑

---

✨ SYNOPSIS ✨

struct idpf_vector_info {
    u16 num_req_vecs;
    u16 num_curr_vecs;
    u16 index;
    bool default_vport;
 };

(no cap, that trailing }; with the space before it is exactly how it's written, we do not touch it 🙈)

🦋 MEMBERS 🦋

• num_req_vecs — the vectors you actually need, based on how many queues the user updated via ethtool. this is the wishlist 📝
• num_curr_vecs — the current number of vectors. and heads up bestie, this one must be >= num_req_vecs ⚠️ — that's not a suggestion, that's the rule, periodt.
• index — the relative starting index for vectors. like where you're hopping on the bus 🚌
• default_vport — yep, a bool, and if it's set, the vectors are for the default vport. simple as 🍓

fr fr though — num_curr_vecs >= num_req_vecs is the one thing to remember. don't be the person who forgets 💀

and that's the page!! credit where it's due: this one comes from ./drivers/net/ethernet/intel/idpf, dated October 2026, and it's filed under the Kernel API Manual, section struct idpf_vector_info(9). slay, documented, iconic, periodt 👑✨💅
