STRUCT UDP_MEDIA_ADDR(9)

💅 struct udp_media_addr(9) 💅

okay bestie, welcome to the Kernel API Manual — this one's a lil struct page for struct udp_media_addr, and honestly? it's giving "small but knows things" energy. stick with me 🫶

---

✨ NAME ✨

struct udp_media_addr — the IP/UDP addressing info 🎀 like, literally where a message is coming from at the bearer level, no cap.

---

🌸 SYNOPSIS 🌸

struct udp_media_addr {
    __be16 proto;
    __be16 port;
    union {
      struct in_addr ipv4;
      struct in6_addr ipv6;
    };
 };

look at her. neat. tidy. two bytes here, two bytes there, and a lil anonymous union doing the most 💅

🦋 Members 🦋

• proto — the Ethernet protocol in use. which flavour of traffic we're talking about, iykyk ⭐
• port — the port being used. the door number, basically 🚪✨
• {unnamed_union} — anonymous. no name, no problem, she's just there being mysterious 🙈 (it's the union holding the address, in case you were wondering)
• ipv4 — IPv4 address of the neighbor 👀 the struct in_addr version
• ipv6 — IPv6 address of the neighbor 🌈 the struct in6_addr version

---

💜 Description 💜

so here's the tea 🍓 — this is the bearer level originating address used in neighbor discovery messages. that's the whole vibe: "hey, this is where I'm coming from" but at the bearer layer.

and this part is important, so I'm saying it loud: all fields should be in network byte order. all of them. every single one. don't be out here putting host byte order in there, I'm begging 😭 (that's what the __be16 types are screaming at you about, fr fr)

go read tipc_udp_enable(9) too, she ate 👑

that's the whole page, bestie 🧚 from ./net/tipc, dated October 2026 — and that's the struct udp_media_addr(9) manual section, wrapped up with a bow 🎀💖
