  * Namespace Support:

  * NVMe devices can have multiple namespaces, each being a independent data

  *
  * As of NVMe 1.1 namespaces can have an 64bit Extended Unique Identifier
  * (EUI64). This driver uses the EUI64 if present to generate the devid and
  * passes it to blkdev to use it in the device node names. As this is currently
  * untested namespaces with EUI64 are ignored by default.
