   5        help
   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.

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

  34         This is a transport driver that enables connected systems to exchange
  35         messages over the ntb hardware.  The transport exposes a queue pair api
  36         to client drivers.
