Subject: scsi: qla2xxx: Increase ql2xmaxqdepth to 64
Patch-mainline: v4.14-rc1
Git-commit: d213a4b7a57175b5025392b2c2e29a2f14f06bc5
References: FATE#322910
ql2xmaxqdepth is the module parameter that seeds the per target
queue depth in the Scsi midlayer (sdev->queue_depth). Performance
testing revealed that increasing this value would improve IOPS
numbers under certain workloads.
