.SH NAME
nvme_mi_mi_xfer \- Raw mi transfer interface.
.SH SYNOPSIS
.B "int" nvme_mi_mi_xfer
.BI "(nvme_mi_ep_t ep " ","
.BI "struct nvme_mi_mi_req_hdr *mi_req " ","
.BI "size_t req_data_size " ","
.BI "struct nvme_mi_mi_resp_hdr *mi_resp " ","
.BI "size_t *resp_data_size " ");"
.SH ARGUMENTS
.IP "ep" 12
endpoint to send the MI command to
.IP "mi_req" 12
request data
.IP "req_data_size" 12
size of request data payload
.IP "mi_resp" 12
buffer for response data
.IP "resp_data_size" 12
size of response data buffer, updated to received size
.SH "DESCRIPTION"
Performs an arbitrary NVMe MI command, using the provided request data,
in \fImi_req\fP. The size of the request data *payload* is specified in
\fIreq_data_size\fP - 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 \fImi_resp\fP, which has an optional
appended payload buffer of \fIresp_data_size\fP bytes. The actual payload
size transferred will be stored in \fIresp_data_size\fP. This size does not
include the MI response header, so 0 represents no payload.
See: \fIstruct nvme_mi_mi_req_hdr\fP and \fIstruct nvme_mi_mi_resp_hdr\fP.
.SH "RETURN"
The nvme command status if a response was received (see
\fIenum nvme_status_field\fP) or -1 with errno set otherwise..
