John Garry 74a2921948 scsi: hisi_sas: Expose HW queues for v2 hw ... As a performance enhancement, make the completion queue interrupts managed. In addition, in commit bf0beec060 ("blk-mq: drain I/O when all CPUs in a hctx are offline"), CPU hotplug for MQ devices using managed interrupts is made safe. So expose HW queues to blk-mq to take advantage of this. Flag Scsi_host.host_tagset is also set to ensure that the HBA is not sent more commands than it can handle. However the driver still does not use request tag for IPTT as there are many HW bugs means that special rules apply for IPTT allocation.
