NAME

       nvme_mi_mi_xfer - Raw mi transfer interface.

SYNOPSIS

       int  nvme_mi_mi_xfer (nvme_mi_ep_t ep , struct nvme_mi_mi_req_hdr *mi_req , size_t req_data_size , struct
       nvme_mi_mi_resp_hdr *mi_resp , size_t *resp_data_size );

ARGUMENTS

       ep          endpoint to send the MI command to

       mi_req      request data

       req_data_size
                   size of request data payload

       mi_resp     buffer for response data

       resp_data_size
                   size of response data buffer, updated to received size

DESCRIPTION

       Performs an arbitrary NVMe MI command, using the provided request  data,  in  mi_req.  The  size  of  the
       request  data  *payload* is specified in req_data_size - this does not include the standard header length
       (so a header-only request would have a size of 0). Note  that  the  Management  Request  Doublewords  are
       considered part of the header data.

       On  success,  response  data  is  stored  in  mi_resp,  which  has an optional appended payload buffer of
       resp_data_size bytes. The actual payload size transferred will be stored  in  resp_data_size.  This  size
       does not include the MI response header, so 0 represents no payload.

       See: struct nvme_mi_mi_req_hdr and struct nvme_mi_mi_resp_hdr.

RETURN

       The  nvme  command  status  if  a response was received (see enum nvme_status_field) or -1 with errno set
       otherwise..
