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

  	 If unsure, say N.

  	help
  	 Support using MSI interrupt forwarding instead of (or in addition to)
  	 hardware doorbells. MSI interrupts typically offer lower latency
  	 than doorbells and more MSI interrupts can be made available to
  	 clients. However this requires an extra memory window and support
  	 in the hardware driver for creating the MSI interrupts.
