[00/15] mpi3mr: Added Support for SAS Transport

Message

Sreekanth Reddy July 29, 2022, 1:16 p.m. UTC

- 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.
