+ 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.

Modified the mpt3sas driver to have a single driver module which support both SAS 2.0 & SAS 3.0 HBA devices, Change List: * Added SAS 2.0 HBA device IDs to the mpt3sas_pci_table pci table. * Created two separate SCSI host templates for SAS2 and SAS3 HBAs. so that, during the driver load time driver can use corresponding host template(based the pci device ID) while registering a scsi host adapter instance for that pci device. * Registered two IOCTL devices, mpt2ctl is for SAS2 HBAs & mpt3ctl for SAS3 HBAs. Also updated the code to make sure that mpt2ctl device to process only those ioctl cmds issued for the SAS2 HBAs and mpt3ctl device to process only those ioctl cmds issued for the SAS3 HBAs. * Added two separate indexing for SAS2 and SAS3 HBAs. * Replaced compile time check 'MPT2SAS_SCSI' to run time check 'hba_mpi_version_belonged' whereever needed. * Aliased this merged driver to mpt2sas using MODULE_ALIAS. * Moved global varaible 'driver_name' to per adapter instance variable. * Created two raid function template and used corresponding raid function templates based on the run time check 'hba_mpi_version_belonged'.
