+DESCRIPTION
+-----------
+For the NVMe device given, sends a capacity management command to
+configure/create/delete the Endurance Groups or NVM Sets with the requested
+operation and element_id. On success, if the Operation is Create Endurance
+group or NVM Set, CQE CDW0 contains Created element identifier else CQE CDW0 is
+reserved.
+
+The <device> parameter is mandatory and may be either the NVMe character
+device (ex: /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1).
