bi-directional commands, OutTransferLength bytes were transferred by OutDataBuffer.

is returned in InTransferLength. For write and bi-directional commands,
OutTransferLength bytes were transferred by OutDataBuffer.
@retval EFI_NOT_READY The ATA command could not be sent because there are too many ATA commands
already queued. The caller may retry again later.
@retval EFI_DEVICE_ERROR A device error occurred while attempting to send the ATA command.
@retval EFI_INVALID_PARAMETER Port, PortMultiplierPort, or the contents of Acb are invalid. The ATA
