oic, it's embedded inside another structure:

struct tcpdiagmsg
{
        __u8    tcpdiag_family;
        __u8    tcpdiag_state;
        __u8    tcpdiag_timer;
        __u8    tcpdiag_retrans;

        struct tcpdiag_sockid id;

        __u32   tcpdiag_expires;
        __u32   tcpdiag_rqueue;
        __u32   tcpdiag_wqueue;
        __u32   tcpdiag_uid;
        __u32   tcpdiag_inode;
};

that's why it's 44...
