Program for dynamically making taps/bridge topologies.

[Alfred Perlstein]

Hello,

Here at Norse we are using bhyve to run our appliance in a test environment.

We have a need for a test network to be made on demand, so this weekend 
I took some time and wrote a tool that allows you to specify a topology 
of bridges and taps that you can then use to create your virtual network.

In our case our test servers have a bridge0 that is static and bridges 
to our private test network.  However we also need a bridge to be 
dynamically that we will generate traffic over in isolation. We then 
need taps created and "assigned" or labeled properly for our QA suite to 
attach to our VMs properly.

We then also need the ability to query the topology and emit the correct 
taps to assign to each vm.

Finally we need the ability to tear down the virtual network once it's 
no longer needed.

This tool provides all three functions.

The tool is available here:
