 Provides the module `Vnetif` which can be used as a replacement for the regular `Netif` implementation in Xen and Unix. Stacks built using `Vnetif` are connected to a software switch that allows the stacks to communicate as if they were connected to the same LAN.
 
-An example of a unikernel that communicates with itself over `Vnetif` can be seen [here](https://github.com/MagnusS/mirage-vnetif/blob/master/examples/connect/unikernel.ml). An iperf-like performance test is available [here](https://github.com/MagnusS/mirage-vnetif/tree/master/examples/iperf_self). The examples can be compiled for Unix and Xen and do not need access to a real network interface.
