   6         The PCI-E Non-transparent bridge hardware is a point-to-point PCI-E bus
   7         connecting 2 systems.  When configured, writes to the device's PCI
   8         mapped memory will be mirrored to a buffer on the remote system.  The
   9         ntb Linux driver uses this point-to-point communication as a method to
  10         transfer data from one system to the other.
