As an enhancement to distribute requests to multiple hardware queues, add the infrastructure to hash a SCSI command into a particular hardware queue. Support the following scenarios when deriving which queue to use: single queue, tagging when SCSI-MQ enabled, and simple hash via CPU ID when SCSI-MQ is disabled. Rather than altering the existing send API, the derived hardware queue is stored in the AFU command where it can be used for sending a command to the chosen hardware queue. Signed-off-by: Matthew R.
