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. if NTB config NTB_MSI	bool "MSI Interrupt Support"	depends on PCI_MSI	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.
