STRUCT FLOW_DISSECTOR_KEY_NUM_OF_VLANS(9)

💖 struct flow_dissector_key_num_of_vlans(9) 💖

okay bestie, welcome to the Kernel API Manual — yes, we're doing kernel docs today and honestly? it's giving study date energy. pull up a chair 🎀

---

✨ NAME ✨

struct flow_dissector_key_num_of_vlans — that's the whole name, no tagline, the manpage literally just drops it and walks away 💅

---

🌸 SYNOPSIS 🌸

ok so here's the whole struct, look at her, she's tiny and iconic:

struct flow_dissector_key_num_of_vlans {
    u8 num_of_vlans;
 };

that's it. one field. one u8. no cap, she's lowkey minimal — main character energy in the smallest possible package 🦋

• num_of_vlans — the num_of_vlans value. yes bestie, that's what the manpage says, it's a self-titled queen 👑. it's the field, it holds the value, that's the vibe.

first up, the source of truth — the kernel file ./include/net/flow_dissector.h (go read it, iykyk 📖✨) — and then the whole entire friend group of sibling structs, and yes we're listing every single one because nobody gets left out:

• struct flow_dissector_key_basic(9)
• struct flow_dissector_key_enc_opts(9)

twenty-one structs and not a single one skipped, we ate that 💀🔥

real talk bestie: this page is short because the struct is short. don't go looking for extra flags or return values, there aren't any — every single detail the manpage had is right here 🫶

and that's a wrap! 💜 this little gem lives in ./include/net, dated October 2026, and it's filed under struct flow_...num_of_vlans(9) — slay, go forth and dissect those flows ✨🌈🎀
