STRUCT TIPC_MEDIA(9)

💅 struct tipc_media(9) — the media specific info exposed to generic bearer layer glow-up

Okay so bestie, welcome to struct tipc_media — it's a kernel API page from the Kernel API Manual, and it's literally the vibe board for how a TIPC media type tells the generic bearer layer what it's about. The whole point? Media specific info exposed to generic bearer layer. No cap. 🎀

✨ NAME ✨

struct tipc_media — media specific info exposed to generic bearer layer. It's giving "backstage pass for your network media type." 🦋

---

🌸 SYNOPSIS 🌸

struct tipc_media {
    int (*send_msg)(struct net *net, struct sk_buff *buf, struct tipc_bearer *b, struct tipc_media_addr *dest);
    int (*enable_media)(struct net *net, struct tipc_bearer *b, struct nlattr *attr[]);
    void (*disable_media)(struct tipc_bearer *b);
    int (*addr2str)(struct tipc_media_addr *addr, char *strbuf, int bufsz);
    int (*addr2msg)(char *msg, struct tipc_media_addr *addr);
    int (*msg2addr)(struct tipc_bearer *b, struct tipc_media_addr *addr, char *msg);
    int (*raw2addr)(struct tipc_bearer *b, struct tipc_media_addr *addr, const char *raw);
    u32 priority;
    u32 tolerance;
    u32 min_win;
    u32 max_win;
    u32 mtu;
    u32 type_id;
    u32 hwaddr_len;
    char name[TIPC_MAX_MEDIA_NAME];
};

👑 Members 👑

So there's like… function pointers up top (the do stuff girlies) and then a little squad of u32s plus a name (the settings girlies). Let's meet them 💖

• send_msg — routine which handles buffer transmission. She's the one actually yeeting the buf out the door, fr fr. ✨
• enable_media — routine which enables a media. Wake her up, she's needed. 🔥
• disable_media — routine which disables a media. Nap time bestie, we're done here. 💀
• addr2str — convert media address format to string. Address in, cute little string out. 🎀
• addr2msg — convert from media addr format to discovery msg addr format. Discovery msg needs its own little addr fit, so we translate. 🦋
• msg2addr — convert from discovery msg addr format to media addr format. The reverse trip, iykyk ✨
• raw2addr — convert from raw addr format to media addr format. Raw and unfiltered → actually usable. 💅
• priority — default link (and bearer) priority. Who gets picked first? Her. Obviously. 👑
• tolerance — default time (in ms) before declaring link failure. So like, your grace period in milliseconds before the link is officially over. 😭
• min_win — minimum window (in packets) before declaring link congestion. Lowkey the floor of the window, measured in packets. 🍓
• max_win — maximum window (in packets) before declaring link congestion. The ceiling, also in packets. Cap it. 🧚
• mtu — max packet size bearer can support for media type not dependent on underlying device MTU. Big energy, very specific use case — don't come for her. 💜
• type_id — TIPC media identifier. Her little ID card. 🌈
• hwaddr_len — TIPC media address len. How long the address is, that's it, that's the tweet. 💖
• name — media name. It's literally her name, in TIPC_MAX_MEDIA_NAME-sized letters. ⭐

And that's the whole page, periodt. 💅 This cutie lives under ./net/tipc, dated October 2026, in the Kernel API Manual — mwah, sending you off with a kiss and a <rainbow>struct tipc_media(9)</rainbow> 🎀✨🦋
