STRUCT DPSW_FDB_MULTICAST_CFG(9)

💖 struct dpsw_fdb_multicast_cfg(9) 💖

okay so this is a page from the Kernel API Manual, and it's all about one lil struct, no cap. bestie, meet struct dpsw_fdb_multicast_cfg — it's literally the glow-up blueprint for a multicast entry in the FDB. she's small, she's iconic, she holds everything the kernel needs to know about one multicast record 🎀

✨ NAME ✨

struct dpsw_fdb_multicast_cfg — "Multi-cast entry configuration", and yes that hyphen is canon, we don't touch it 💅

---

🦋 SYNOPSIS 🦋

struct dpsw_fdb_multicast_cfg {
    enum dpsw_fdb_entry_type type;
    u8 mac_addr[6];
    u16 num_ifs;
    u16 if_id[DPSW_MAX_IF];
};

look at her. four fields. zero notes. main character energy fr fr 🌸

💜 Members 💜

okay let's go through the squad one by one, iykyk:

• type — the vibe check for the entry: you're picking whether it's a static entry or a dynamic one. choose wisely bestie 👑
• mac_addr — the MAC address, plain and simple. six bytes of pure identity. it's giving "who even am I" but in hex 🙈
• num_ifs — how many interfaces are in on this, both the external ones and the internal ones. count 'em, don't skip 'em 🔥
• if_id — the egress interface IDs, stored in a DPSW_MAX_IF-sized array. this is the "where do we actually send this" list, and she's got room for the whole crew 💅

ngl there is genuinely nothing else on this page — that's the whole struct. short page, huge slay ⭐
