NAME
       libnvme_mi_mi_pda_read - Read the NVMe-MI Persistent Data Area (PDA)

SYNOPSIS
       int libnvme_mi_mi_pda_read (struct libnvme_mi_ep *ep , enum
       nvme_mi_pda_dformat dformat , __u32 dofst , __u32 dlen , void *data ,
       size_t *data_len );

ARGUMENTS
       ep          endpoint for MI communication

       dformat     data format to use for dofst and dlen, see enum
                   nvme_mi_pda_dformat

       dofst       starting offset, in units of dformat, into the PDA to read

       dlen        length, in units of dformat, to read from the PDA starting
                   at dofst

       data        buffer to receive the PDA contents

       data_len    in: size of data; out: length of data actually returned

DESCRIPTION
       Performs an NVMe-MI PDA Read command. See the PDA Size (PDAS) and
       Supported Data Format (SDFORMAT) fields of struct nvme_mi_port_smb for
       the size and supported dformat values of the PDA on a given port.

RETURN
       The nvme command status if a response was received (see enum
       nvme_status_field) or negative error code otherwise.
