- To reflect work flow. NewDriver() => ConfigureDriver() and no NetworkDriver returned. libnetwork clients would refer to a driver/network type, then internally controller will retrieve the correspondent driver instance, but this is not a concern of the clients. - Remove NetworkDriver interface - Removed stale blank dependency on bridge in libnetwork_test.go Signed-off-by: Alessandro Boch <aboch@docker.com>
