1. Add the Tape drive fix to the driver: If the command is for
the tape device, set the pthru timeout to the os layer timeout value.
2. Add Poll_wait mechanism to Gen-2 Linux driv.
In the aen handler, driver needs to wakeup poll handler similar to
the way it raises SIGIO.
3. Add new controller new SAS2 support to the driver.
4. Report the unconfigured PD (system PD) to OS.
5. Add the IEEE SGL support to the driver
6. Reasign the Application cmds to SAS2 controller
