Provides an interface to the Virtual Network device known as a TAP device. Ethernet is an ISender, meaning to write to the device, one must call the Send method. It is also an ISource, meaning to receive packets one must subscribe via the Subscribe method to the output.
Inheritance: SimpleSource, ISender
