Send a NVMe−MI Send command to the specified device, return results.
The <device> parameter is mandatory and may be either the NVMe character device (ex: /dev/nvme0) or block device (ex: /dev/nvme0n1).
On success it returns 0, error code otherwise.
−o <opcode>, −−opcode=<opcode>
The NVMe−MI opcode to send to the device in the command
−n <nsid>, −−namespace−id=<nsid>
The value for the ns−id in the command.
−l <data−len>, −−data−len=<data−len>
The data length for the buffer used for this command.
−m <nmimt>, −−nmimt=<nmimt>
The value for the NVMe−MI message type in the command.
−0 <nmd0>, −−nmd0=<nmd0>
The value for the NVMe management request dword 0 in the command.
−1 <nmd1>, −−nmd1=<nmd1>
The value for the NVMe management request dword 1 in the command.
−i <file>, −−input−file=<file>
If the command is a data−out (write) command, use this file to fill the buffer sent to the device. If no file is given, assumed to use STDIN.
• Has the program issue a nvme−mi−send to execute the VPD write.
