## When VirtioScsiDxe is instantiated for a HBA, the numbers of targets and
# LUNs are retrieved from the host during virtio-scsi setup.
# MdeModulePkg/Bus/Scsi/ScsiBusDxe then scans all MaxTarget * MaxLun
# possible devices. This can take extremely long, for example with
# MaxTarget=255 and MaxLun=16383. The *inclusive* constants below limit
# MaxTarget and MaxLun, independently, should the host report higher values,
# so that scanning the number of devices given by their product is still
# acceptably fast.
