For NVMe over PCIe, the program uses knowledge of the +sysfs layout to map the device to the pci resource stored there and mmaps the +memory to get access to the registers. For NVMe over Fabrics, the programs +sends a fabric command to get the properties of the target NVMe controller. +Only the supported properties are displayed. + +OPTIONS +------- +-H:: +--human-readable:: + Display registers or supported properties in human readable format. + +-o <format>:: +--output-format=<format>:: + Set the reporting format to 'normal', 'json', or + 'binary'.
