STRUCT FLOW_DISSECTOR_KEY_IP(9)

💅 struct flow_...ector_key_ip(9) — the Kernel API Manual, bestie edition 🎀

okay so real talk, this is a page out of the Kernel API Manual, and the struct in question lives at struct flow_...ector_key_ip(9). The title's got that truncated <italic>flow_...ector_key_ip</italic> energy because the header line ran out of room, and honestly? iconic. mysterious. a little cunty of it. 💀

Also iconic: the NAME section down there is literally the struct name and then nothing. No description. Not a single crumb. She said "the struct is the vibe, look it up" and left. 🙈

✨ NAME ✨

struct flow_dissector_key_ip — (and that's it, that's the whole description. the dashes are holding a space for a blurb that never texted back) 😭

---

🦋 SYNOPSIS 🦋

the whole thing. the entire struct. look at her go:

struct flow_dissector_key_ip {
    __u8 tos;
    __u8 ttl;
 };

two __u8 fields, that's the entire personality. small but mighty, lowkey. ✨

🌸 Members 🌸

• tos — the member called tos. yes, its description is also just "tos". the manpage is not giving us lore here, she's just pointing at the thing and going "that one." 💅
• ttl — the member called ttl. same deal, bestie. its description is literally ttl. no cap, that's what's written. 🫶

ngl the Members section is doing the absolute bare minimum and we have to respect it. what's written is what's written. 📝

okay that's the whole page, bestie!! 🎀 source path is ./include/net and the date on this one is October 2026, so she's stamped and dated and ready. slay. periodt. 💖🌈⭐
