ARGUMENTS
       cmd         Passthru command to use

       nsid        Namespace ID

       slba        Starting logical block

       nlb         Number of logical blocks (0-based)

       control     Upper 16 bits of cdw12

       dsm         Data set management attributes (CETYPE is zero), see enum
                   nvme_io_dsm_flags

       cev         Command Extension Value (CETYPE is non-zero)

       data        Pointer to user address of the data buffer

       data_len    Length of user buffer, data, in bytes

       metadata    Pointer to user address of the metadata buffer

       metadata_len
                   Length of user buffer, metadata, in bytes

DESCRIPTION
       Initializes the passthru command buffer for the Read command.

NOTE
       Assumes a macro or separate function exists to translate the combined
       NLB/control/prinfo fields into cdw12/cdw13. This transformation assumes
       the parameters are used for a generic nvme_init_io wrapper.
