717 * The registration login mailbox command is used to register an N_Port or
718 * F_Port login. This registration allows the HBA to cache the remote N_Port
719 * service parameters internally and thereby make the appropriate FC-2
720 * decisions. The remote port service parameters are handed off by the driver
721 * to the HBA using a descriptor entry that directly identifies a buffer in
722 * host memory. In exchange, the HBA returns an RPI identifier.
723 *
724 * This routine prepares the mailbox command for registering remote port login.
725 * The function allocates DMA buffer for passing the service parameters to the
726 * HBA with the mailbox command.
727 *
728 * Return codes
729 * 0 - Success
730 * 1 - DMA memory allocation failed
