For the NVMe device given, sends an identify command for namespace list and provides the result and returned structure.
The <device> parameter is mandatory and may be either the NVMe character device (ex: /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1). If the starting namespace in the list always begins with 0 unless the '--namespace-id' option is given to override.
On success, the namespace array is printed for each index and nsid for a valid nsid.

-n <nsid>, --namespace-id=<nsid>
Retrieve the identify list structure starting with the
given nsid.
-y <command_set_identifier>, --csi=<command_set_identifier>
If this value is given, retrieve the identify list
structure associated with the speicified I/O command set.
-a, --all
Retrieve the identify list structure for all namespaces
