>[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.
