STRUCT MUX_ADTH(9)

🎀 struct mux_adth(9) 🎀

okay so bestie, welcome to the kernel API manual for struct mux_adth, and yes it's literally the Structure of the Aggregated Datagram Table Header 💅 like that's the whole name, no notes.

✨ SYNOPSIS ✨

struct mux_adth {
    __le32 signature;
    __le16 table_length;
    u8 if_id;
    u8 opt_ipv4v6;
    __le32 next_table_index;
    __le32 reserved2;
    struct mux_adth_dg dg[];
 };

look at that little layout bestie, it's giving "packed and ready to party" 🫶 and no, you cannot just reorder it, the fields are in that order, periodt.

🌸 Members 🌸

• signature — the signature of the Aggregated Datagram Table Header. it's the vibe check of the whole struct, ngl ✨
• table_length — length, in bytes, of the datagram table. bytes, not vibes. bytes 💀
• if_id — the ID of the interface that the datagrams in the table belong to, so you know whose table this is 🎀
• opt_ipv4v6 — the IPv4 (=0) / IPv6 (=1) hint. lowkey just a tiny flag doing big main character work 🌈
• next_table_index — index (in bytes) to the next Datagram Table in the buffer. yes, in bytes, keep up 💅
• reserved2 — reserved bytes. set to zero, always, no cap, do not put anything cute in there 🙈
• dg — the datagramm table with variable length 🦋 (spelled datagramm in the original, and honestly? iconic. we keep it.)
