Constants

       NVME_CTRL_DSTO_SDSO_SHIFT
                   Shift amount to get the value of Single Device  Self-test  Operation  from  Device  Self-test
                   Options field.

       NVME_CTRL_DSTO_HIRS_SHIFT
                   Shift  amount  to  get  the  value  of   Host-Initiated Refresh Support from Device Self-test
                   Options field.

       NVME_CTRL_DSTO_SDSO_MASK
                   Mask to get the value of Single Device Self-test Operation

       NVME_CTRL_DSTO_HIRS_MASK
                   Mask to get the value of Host-Initiated Refresh Support

       NVME_CTRL_DSTO_ONE_DST
                   If set, then the NVM subsystem supports only one device self-test operation in progress at  a
                   time.  If  cleared,  then  the  NVM  subsystem  supports  one  device self-test operation per
                   controller at a time.

       NVME_CTRL_DSTO_HIRS
                   If set, then the controller supports the Host-Initiated Refresh capability.
