Multiport network adapter loopback hardware

Abstract:

An instruction directed towards a network adapter is detected. Based on the detected instruction it is determined that the network adapter should operate in a loopback mode. One or more network signals are transmitted through a dedicated loopback pathway. The transmission is based on the determination. The transmission occurs on a first network interface of the network adapter. The dedicated loopback pathway connects to a second network interface of the network adapter. Listening on the dedicated loopback pathway for the one or more network signals. Performing a network loopback test of the network adapter based on the listening.
