nicira拡張では、nicira_headerという構造体にメッセージを格納してやる必要があります。

/* Header for Nicira vendor requests and replies. */
struct nicira_header {
    struct ofp_header header;   /* type == OFPT_VENDOR */
    ovs_be32 vendor;            /* NX_VENDOR_ID. */
    ovs_be32 subtype;           /* See the NXT numbers in ofp-msgs.h. */
};
