[PATCH 1/2] fusion : shost max_id not set in VMWare guest os
In vmware guest os with emulated LSI 53c1030, the port facts config page is
not having MaxDevices initialized to 16 devices. Instead its set to zero.
Thereforewhen driver loads, no devices are scanned for from scsi_scan_host.
Prior to the3.04.04 driver, shost max_id was set to hard coded value
MPT_MAX_SCSI_DEVICES. After that release, support for greater than 255 targets
was added, and the driver was taking the target count from the port facts
instead. With this patch we will restore the hard coded values for SPI, but at
the same time use the settingsneeded for SAS and Fibre Channel.
