-config SCSI_MPT2SAS

- depends on PCI && SCSI
- select SCSI_SAS_ATTRS
- select RAID_ATTRS
- ---help---
- This driver supports PCI-Express SAS 6Gb/s Host Adapters.

-config SCSI_MPT2SAS_MAX_SGE
- int "LSI MPT Fusion Max number of SG Entries (16 - 128)"
- depends on PCI && SCSI && SCSI_MPT2SAS
- default "128"
- range 16 128
- ---help---
- This option allows you to specify the maximum number of scatter-
- gather entries per I/O. The driver default is 128, which matches
- SAFE_PHYS_SEGMENTS. However, it may decreased down to 16.
- Decreasing this parameter will reduce memory requirements
- on a per controller instance.
