STRUCT OVS_HEADER(9)

🌸 struct ovs_header(9) 🌸

okay so bestie, welcome to the Kernel API Manual entry for struct ovs_header — she's small, she's iconic, she's literally the header for OVS Generic Netlink messages 💅

---

✨ NAME ✨

struct ovs_header — the header for OVS Generic Netlink messages. that's her whole job and she ate 🎀

---

🦋 SYNOPSIS 🦋

struct ovs_header {
    int dp_ifindex;
 };

look at her. one member. main character energy fr fr 👑

---

🍓 Members 🍓

• dp_ifindex — the ifindex of the local port for the datapath 💖 and ooh, key detail: set it to 0 if you wanna make a request that's not specific to a datapath. no cap, that zero matters 🫶

---

🌈 Description 🌈

so here's the vibe check: the attributes that come after the header are specific to one particular OVS Generic Netlink family — like each family has its own little aesthetic ✨ — but all of the OVS families use this header. every single one. she's the shared glue, the group chat everyone's in 💀💖

lowkey a whole reading list but trust me, it's worth it 🧚‍♀️💜

and that's the tea, babe — this page lives in ./include/uapi/linux, dated October 2026, and she's filed under struct ovs_header(9). slay, go read some kernel headers for me 💅💖🌸
