  config SCSI_MPT3SAS
  	tristate "LSI MPT Fusion SAS 3.0 Device Driver"
  	depends on PCI && SCSI
  	select SCSI_SAS_ATTRS
  	select RAID_ATTRS
  	---help---
  	This driver supports PCI-Express SAS 12Gb/s Host Adapters.
  
  config SCSI_MPT3SAS_MAX_SGE
  	int "LSI MPT Fusion Max number of SG Entries (16 - 256)"
  	depends on PCI && SCSI && SCSI_MPT3SAS
  	default "128"
  	range 16 256
  	---help---
  	This option allows you to specify the maximum number of scatter-
  	gather entries per I/O. The driver default is 128, which matches
  	MAX_PHYS_SEGMENTS in most kernels.  However in SuSE kernels this
  	can be 256. However, it may decreased down to 16.  Decreasing this
  	parameter will reduce memory requirements on a per controller instance.
  
  config SCSI_MPT3SAS_LOGGING
  	bool "LSI MPT Fusion logging facility"
  	depends on PCI && SCSI && SCSI_MPT3SAS
  	---help---
  	This turns on a logging facility.
