 * Structure of management datagram sent by the SRP target implementation.
 * Contains a management datagram header, reliable multi-packet transaction
 * protocol (RMPP) header and ib_dm_hdr. Notes:
 * - The SRP target implementation does not use RMPP or ib_dm_hdr when sending
 *   management datagrams.
 * - The header size must be exactly 64 bytes (IB_MGMT_DEVICE_HDR), since this
 *   is the header size that is passed to ib_create_send_mad() in ib_srpt.c.
 * - The maximum supported size for a management datagram when not using RMPP
 *   is 256 bytes -- 64 bytes header and 192 (IB_MGMT_DEVICE_DATA) bytes data.
