Submits an NVMe Directive Receive admin command and returns the applicable results. This may be the combination of directive type, and operation, as well as number of requested resource if specific operation needs it.
The <device> parameter is mandatory and may be either the NVMe character device (ex: /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1).
On success, the returned directive’s parameter structure (if applicable) is returned in one of several ways depending on the option flags; the structure may parsed by the program and printed in a readable format if it is a known structure, displayed in hex, or the raw buffer may be printed to stdout for another program to parse.

It is probably a bad idea to not redirect stdout when using this mode.
