- Enhanced the driver to support SAS transport layer and
 expose SAS controller PHYs, ports, attached expander, expander PHYs,
 expander ports and SAS/SATA end devices to the kernel through
 SAS transport class.
- The driver also provides call back handlers for get_linkerrors,
 get_enclosure_identifier, get_bay_identifier, phy_reset, phy_enable,
 set_phy_speed and smp_handler to the kernel as defined by the
 SAS transport layer.
- The SAS transport layer support is enabled only when the
 controller multipath capability is not enabled.
- The NVMe devices, VDs, vSES and PCIe Managed SES devices
 are not exposed through SAS transport.

V2:
 - Accommodated the changes suggested by Himanshu Madhani

Sreekanth Reddy (15):
  mpi3mr: Add config and transport related debug flags
  mpi3mr: Add framework to issue cnfg requests
  mpi3mr: Added helper functions to retrieve cnfg pages
  mpi3mr: Enable Enclosure device add event
  mpi3mr: Add framework to add phys to STL
  mpi3mr: Add helper functions to retrieve device objects
  mpi3mr: Add helper functions to manage device's port
  mpi3mr: Enable STL on HBAs where multipath is disabled
  mpi3mr: Add expander devices to STL
  mpi3mr: Get target object based on rphy
  mpi3mr: Add SAS SATA end devices to STL
  mpi3mr: Add framework to issue MPT transport cmds
  mpi3mr: Support sas transport class callbacks
  mpi3mr: Refresh sas ports during soft reset
  mpi3mr: Block IOs while refreshing target dev objects

Out of curiosity, are there any plans to add SCSI transport SAS support 
for megaraid sas?

Thanks,

No plan to add SAS transport support for megaraid_sas.
