 * For SMI, ClassId can be MCLASS_SM_LID_ROUTED or MCLASS_SM_DIRECTED_ROUTE

 * either can receive SMI packets regardless of actual ClassId of packet

 * This helps to reduce complexity in SM's using this interface

 * Any other ClassId will register for the GSI interface

 *

 * The ClassId only affects inbound packets.  The registration can be used

 * to send any request packet in any class and corresponding responses

 * (with same transaction id) will be returned to the sender.

 * If registered for an SMI ClassId, all sends will be via QP0, if

 * registered for a GSI ClassId all sends will be via the GSI QP.

 *

 * Unsolicited packets will be delivered based on their Method and R bit fields

 * and the "is" flags below will select which packets a given consumer desires.

 * A given unsolicited packet can be delivered to more than 1 consumer.

 *

 * A given registration is for a single local port, all sends and receives
