-Building and Installation
+The VF Driver
+==================
+The VF driver is normally used in a virtualized environment where a host
+driver manages SRIOV, and provides a VF device to the guest. With this
+first release the only host environment tested was using Linux QEMU/KVM.
+Support is planned for Xen and VMWare hosts at a later time.
+
+In the FreeBSD guest the IXLV driver would be loaded and will function
+using the VF device assigned to it.
+
+The VF driver provides most of the same functionality as the CORE driver,
+but is actually a slave to the Host, access to many controls are actually
+accomplished by a request to the Host via what is called the "Admin queue".
+These are startup and initialization events however, once in operation
+the device is self-contained and should achieve near native performance.
+
+Some notable limitations of the VF environment: for security reasons 
+the driver is never permitted to be promiscuous, therefore a tcpdump
+will not behave the same with the interface. Second, media info is not
+available from the PF, so it will always appear as auto.
+
+Tarball Building and Installation
