Sreekanth Reddy f92363d123 [SCSI] mpt3sas: add new driver supporting 12GB SAS
These driver files are initially, substantially similar to mpt2sas but,
because mpt2sas is going into maintenance mode and mp3sas will become heavily
developed, we elected to keep the code bases separate.

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.
