A communication path is established that allows for communication between a filter
graph space and a network driver space in a system. The communication path allows
bi-directional communication between a filter graph driver in the filter graph
space and a network driver in the network driver space. Addresses of data can be
passed from the network driver to the filter graph driver, which allows the filter
graph driver to communicate with a filter graph manager as necessary to configure
the filter graph space to obtain data from the requested address. The data obtained
from the address is then passed from the filter graph driver to the network driver.
