For the NVMe device given, sends the Seagate vendor log
request and either saves the result to a file or dumps the content to stdout.
The <device> parameter is mandatory and may be either the NVMe
character device (ex: /dev/nvme0), or a namespace block device (ex:
/dev/nvme0n1).
The log contents may be associated with the controller, in which case the namespace parameter is ignored.
Two logs exist, page 0xC4 (Extended SMART log page) and page 0xCF (DRAM Supercap SMART log page)
This command will only work on Seagate devices supporting this feature. Not
all commands work across all product families.
