config SCSI_MPT3SAS
tristate "LSI MPT Fusion SAS 3.0 & SAS 2.0 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_MPT2SAS_MAX_SGE
int "LSI MPT Fusion SAS 2.0 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.

Dummy config option for backwards compatibility: configure the MPT3SAS
driver instead.
