.SH "DESCRIPTION"
.sp
For the NVMe device given, issues the I/O Management Send command with the requested management operation (mo) and management operation specific parameter (mos)\&. This is the generic interface provided for forward compatibility as new operations are added that this program isn\(cqt aware of at the time of its development\&. As such, this is a generic command that does not provide any convenience parameters to produce the binary payload\&.
